Current Measurement

It is possible in some cases to measure currents from 1 mA and the design is to condition the signal present at the output of the current transformer and apply it to a microcontroller whenever we need a large measuring range where the voltage must reach low values in low current, and we must convert the signal AC to DC.

The rectifier circuit and voltage conditioner have been extended with the intention of making the current transformers more flexible. It is very interesting to use current transformers, in the measurement of electric current, because of the insulation ensuring between the measurement circuits and the network to be measured.

In addition, when well dimensioned, the transformer presents optimum linearity and precision, with a low cost and the market standard for current transformers, it contemplates secondary with current of 5 A, which is advantageous in the measurement of high currents, above 100 THE.

Thus, in order to measure smaller currents, the use of transformers with secondary currents of lesser currents is more advised, ie secondary ones of 1A, 0.1 A or less. In most cases – including current transformers with 5 A secondary, there is the precision of amplifying the signal provided in the secondary, which requires the application of an operational amplifier.

The Three Phase Transformer

The three-phase transformer has a three-phase core, the windings can be associated in connections called a star or delta. This choice depends on factors such as access to neutral, conductor gauge by phase, insulation level, grounding system, angular lag required, etc.

The values ​​assigned for the maximum equipment voltage in kV, nominal voltage and primary and secondary connection of the transformer can be observed.

The electrical parameters of a transformer are determined according to maximum acceptable losses, according to ABNT NBR 5440 (1999):

– Nominal power – The nominal power of a transformer means the conventional apparent power value, which serves as the basis for the design, testing and manufacturer’s guarantees, and which determines the value of the rated current under the specific conditions in the respective rules adopted in the electricity sector.

– Relation of voltages and derivations – Among the types of connection the most used, in the secondary distribution of electric energy. The primary of the transformer has its delta or triangle connected windings each having a voltage of 13.8 kV. The secondary has the windings connected in star and the central node is called neutral, which adds a fourth conductor to the circuit; this can be observed through the four wires that appear in the intermediate part of the poles in an electrical distribution network.

The Rotors in Short Circuit

In induction electric motors in operation, the magnetic field produced in the rotor circuit will run through the entire rotating stator field. Consequently, at the exact moment when the motor is energized, it will operate as a transformer with the short-circuit secondary, requiring a higher current than the rated current from the mains, reaching an average of up to eight times the value of the same .

Thus, there are some basic concepts that should be properly understood and adopted. The induction electric motor with squirrel cage type rotor is made by the stator, which impinges on a magnetic circuit of the electric motor of the grooved type, in which are installed coils that, with correct connection, give the magnetic field rotating.

In this way, three-phase induction motors with squirrel cage rotor are the most commercially available to be applied in the industry. It receives this qualification because of the type of rotor used, which is shorted. Another element is called rotor, which consists of a winding composed of copper or aluminum bars, short-circuited at their ends. The current in the rotor circuit is induced by the actuation of the rotating field of the stator.

The Synchronous Generators

A single-phase synchronous AC generator is a type of machine that, although it can be built, does not exist in practice, it is only for didactic purposes and is called the elementary generator.

The winding of the armature is made up of a single coil of turns which are assembled into two single diametrically opposite grooves in the inner periphery of the stator. When the rotor rotates, driven by a primary organ, the magnetic flux through the coil will change and voltages will be induced in the armature winding.

The conductors composing these two sides of the coil are parallel to the machine axis and are connected in series by end connections. The winding producing the magnetic field in the rotor is fed by direct current, which is led to it by means of carbon brushes that slide on collector rings.

The rotor rotates at a steady speed, driven by a primary member mechanically coupled to the rotor shaft. The spatial distribution of the magnetic induction in the air gap is as a function of the angle θ along the inner periphery of the stator. The magnetic induction waveform of the actual machines can approach a sine wave by the correct shape conformation of the pole shoes and as the rotor rotates the magnetic flux associated with the magnetic induction wave.

Mechanical Energy in CC

Taking into account that the stator body is made of various ferromagnetic elements, when the voltage is applied to the terminals of the field winding of the machine, an energization of the magnetic fields is automatically arranged therein. In this way, because it is a generator, the mechanical energy is removed by the application of a torque and the rotation of the machine axis.

Thus, a mechanical energy source may refer to a hydraulic or wind turbine, for example, and the mechanical energy source generates relative motion between the electric conductors of the armature windings and the magnetic field caused by the field winding.

Consequently, it is concluded that the mechanical energy which is presented to the axis of the DC machine is properly stored in the magnetic field thereof to be transmitted so as to feed the load connected to the machine. In this type of motor, the operation is contrary, since the electric power is offered to the conductors of the armature winding by the use of an electric voltage at its terminals by the switch ring, causing an electric current to circulate in this winding that generates a field the winding of the armature.

Lifetime of the Solid Insulation Material

The insulation system of a transformer is somewhat doubtful, since the geometry of the conductor varies, the operating temperature of the insulation material is indeterminate and the stresses generated by the voltage transients are also indeterminate. Thus, to the design of the transformer insulation system must be added some factors so that the insulation of the equipment can be efficiently evaluated.

Using Eq. (4.2), if U1 is known for temperature T1, we can calculate the new life time U2 of the insulation for a given temperature T2. The final life time of the insulation material is estimated when it consumes half of its initial value. The life of a transformer is related to its insulation system, its insulation material and the production process of the material.

The solid insulation system has certain properties necessary for the proper operation of the transformer. At first, the material can withstand stresses well, but over time the insulation deteriorates, until a failure of the insulation occurs. These stresses are usually caused by temperature and voltage gradients.

Thermal Properties

In the course of all the projecting action of an electric motor, whatever its category, the wires are exposed to mechanical forces of bending, traction and abrasion. In the process of operation, the thermal and electrical effects must also manifest on the insulation element of the wire, and must have a satisfactory mechanical, electrical and thermal insulation.

In order to meet the requirements determined by the market, as well as specific applications with effective technical performance, there are some systems suitable for different types of electric motors.

We have verified that laminates with insulating properties and films must make the electrical and thermal insulation of the parts of the motor coil and it is a common practice that the enamel used in the wires guarantees these properties, since the mechanical property endorsed by the external layer of the enamel forces during the insertion period thereof into the stator grooves.      HF-12CG

The enamel layer located inside the wires affirms a high dielectric strength to the assembly, assigning a two hundred degree grade to the wire. The enamelled circular wire is one of the elements of great importance of the motor, since the electric current that circulates in its interior is capable of producing a magnetic field essential for the efficient operation of the motor.

The connection of Single Phase Motors

Like three-phase motors, single-phase electric motors are designed to operate at two different voltages, such as 110-220 V or 220-440 V. Some flexibility is allowed in this voltage, for example, windings can operate in the range of 110 to 127 V without causing problems. The connections must be made in such a way that the tension in the windings is always smaller, between those specified in the motor plate.

The voltage-to-current mismatch is achieved through the capacitor, helping the motor to achieve a high starting torque. The most commonly used single-phase motor is the one that applies an auxiliary starting coil in series with a capacitor suitable for that use, in series with a centrifugal switch, called auxiliary phase or starting auxiliary coil. The motor is made by two more coils, called main coils or working coils.

The auxiliary coil is only carried by the electric current at the motor starting, because when the motor reaches close to 85% of the value of its nominal speed, through the centrifugal force generated by the rotation of the rotor, it causes the contact of the switch to open thus the current flowing over the auxiliary coil.

The Three Phase Rider

The three-phase brake motor is based on an induction electric motor that is inserted into a single-disc brake, thus forming a compact integral unit. The drive coil of the electromagnet, which receives an epoxy resin protection, operates at higher or lower than nominal voltages.

The energizing coil of the electromagnet is controlled by means of a direct current, given by a rectifier bridge that offers silicon diodes and varistors, suppressing inappropriate peaks of tension, thus causing a rapid disconnection of the current. The DC power supply ensures more agility and uniformity of brake performance.

The induction motor is fully enclosed and features external ventilation with similar specifications of engine line performance and strength. The brake is made of some moving parts, which guarantee a long life with practically no maintenance. The double face of pellets can form a wide friction surface, which generates a reduced pressure on them, reduced heating and little wear. Generally, the brake cools through proper engine ventilation.

The Harmonics

The effects of the harmonics caused by their activation can affect the operation, service life and engine performance. Current harmonics can emit and develop greater audible noise. The motors shall demonstrate that the noise level limit is received when these are connected by static frequency inverters. In addition, the harmonics also contribute to the pulsating torque and these effects can be subdivided into three categories:

– heating;

– dielectric;

– mechanical.

The current harmonics are integral with the fundamental current, so they generate extra heat in the motor windings and even a 30% (thirty percent) value of current interference in an engine causes no more than 8% (eight percent) of additional heat, especially to the motor windings that react as a filter.

It is necessary for the drive manufacturer to inform the engine operator, with data on the harmonics built to make the engine properly made with the optimum heat dissipation and absorption capacity, to overcome any additional losses or overheats. An engine operating at an uncertain speed, using a frequency inverter, must meet the same temperature rise limits as a pure sine wave motor.

Food Systems

It is important to know that power systems may belong to single-phase or three-phase categories. If several single-phase motors are connected to the three-phase system, which consists of three single-phase systems, it is imperative that care be taken in the distribution process to be made invariably, avoiding load unbalance between the phases.

The single-phase system is generally applied in domestic, commercial and rural uses, while the three-phase system is used in industrial services, with systems with a frequency of 60 Hz. The three-phase voltages most used in industrial networks are low voltage, which can vary with 220V, 380V and 440V; high voltage, with 2.300V, 4.160V and 6.600V.

The three-phase low voltage star system is based on three phase conductors and the neutral conductor connected to the star point of the generator or to the secondary winding of the transformers. The standard single-phase voltages are 127V and 220V.

Single-phase motors can be activated in two phases, which is the UL line voltage, or a phase and neutral, which is the phase voltage Uf. Therefore, the nominal voltage of the single-phase motor must be similar to the UL or Uf voltage of the system.

Engine Specifications

It is possible to affirm that many of the existing motors can offer the actual values ​​typical of the conjugates that surpass the values ​​required in norm. In most cases engines may even exceed the minimum required for a category such as H, for example.

By means of the high value of the maximum torque, they can face without extreme loss of rotation, the momentary peaks of load and the falls, thus making the tension evaluated fleeting. This factor becomes essential for the activation of machines subject to high load peaks, such as crushers and calenders, for example.

The Electrical System

The electric motor is a fundamental machine in industries, since it represents on average 60% of the energy consumption and in this way, it is necessary to use motors with power and specifications correct to their function, once the power factor will change with the engine load.

Power factor elevation is promoted by the bonding of a capacitive load, usually a capacitor or synchronous motor in action in parallel with the load, as in the case of a four-pole, 100-volt three-phase electric motor operating at 100% rated power, with original power factor and high efficiency. With the sum of all these factors, it will be possible to calculate the reactive power required to increase the power factor.   Boston Gear 31974 M1621-16

In order to improve the good use of the electric system, by reducing the transit of reactive energy in transmission, subtransmission and distribution lines, it is advisable that the reference power factor of the loads go from 0.85 to 0.92. Changing the power factor will provide a higher availability of active power in the system, since reactive power may restrict the carrying capacity of useful energy.

The electric motor will be monitored by means of one of the NO contacts of the relay, while the three phases are present, the relay remains on and when there is a phase missing, the switch opens, turning off the motor. In this way, with just a very simple circuit, we can control powerful machines, such as those found in industrial plants. The phase-loss relay consists of an electronic-electronic component that monitors the presence or absence of the three phases. If a phase is missing, the relay prevents the circuit from working. https://www.mrosupply.com/hydraulics-and-pneumatics/hose-reels/773736_5600omp_reelcraft/

Asynchronous motor starters

When an electric motor is put into operation, the required mains current is increased and can, especially if the section of the power conductor is insufficient, cause a voltage drop that may affect the operation of the loads. Sometimes this voltage drop is such high way that it is noticeable in lighting appliances. To avoid these drawbacks, some dealers’ facility regulations prohibit the use of engines with direct starting above a given power. Others simply impose, as a function of engine power, the relationship between the starting current and the rated current.

The short-circuit rotor motor is the only one that can be directly connected to the network, through simple devices, since the characteristics of the rotor are determined. Since the rotor characteristics are determined by the manufacturer, the various starting processes generally consist of varying the voltage at the stator terminals. In this type of motor, with constant frequency, the reduction of the peak of current is automatically accompanied by a strong reduction of the conjugate. Only the ends of the stator windings will be available on the terminal board.

Three-phase induction motors

Three-phase induction motors (MIT) are suitable for connection to three-phase electrical systems and are the most widely used electric motors in the industry. They guarantee better operating conditions than single-phase motors because they do not need startup aid. And they have a higher yield and are found at higher potencies. The designs of three-phase AC motors are less complicated than DC motors. In addition, the absence of mobile contacts in its structure ensures its operation for a long period, without the need for maintenance. Its speed will be determined by the frequency of the power supply, which guarantees excellent conditions for its operation at constant speeds.

The operating principle of this engine is basically the same as all electric motors hose reel parts. It is based on the iteration of the magnetic flux with a current in a conductor, resulting in a force on the conductor. Its power is supplied by a three-phase balanced voltage source. The cost of MIT is much less than the DC motor of the same power and its maintenance is simpler and cheaper, having its lower power consumption.

Principles of Balancing

It is recommended that the electric motors be dynamically balanced with the so-called half-no-load key, which are properly decoupled. The specific balancing required must be requested from the manufacturer at the time of purchase of the engine. Transmission components, as well as pulleys and couplings, among many other existing types need to be fully balanced before starting the installation process on the axes of the respective motors. Engines driven without the coupled transmission components must contain their specific key, firmly, securely or removed, so that it is possible to prevent any kind of accidents that may occur regardless of the reason.

Therefore, equipment that is unbalanced can cause vibrations that can cause serious damage to the motor cygnus tension control. For applications with direct coupling, it is advisable to use ball bearings. A tension, if present in excess in the belts, is capable of damaging the bearings completely and may cause the motor shaft to rupture. In this way, the degree of balance quality of the engine must comply with the standards in force for each product line.

Elements of Impregnation

The varnishes are considered as great allies when it comes to impregnation, being applied by immersion and finished in an oven. The resins, which are extremely relevant for this purpose, do not present solvents in their formulas, being applied by a process called continuous flow. The filling of the voids helps in the thermal dissipation of the heat produced by the driver and in applications of motors fed by frequency inverters reduces and even prevents the formation of partial discharges inside the motor 8CG83. Currently, two different types of impregnating resins and varnishes are used.

It can be stated that the impregnation resins and varnishes are capable of keeping all the enameled coil wires properly bonded together with all stator components, eliminating all voids existing within the groove. The joining of the wires does not allow them to get in friction and vibrate with each other. This friction would result in wire enamel faults, which could lead to a short circuit. Impregnation elements such as resins and varnishes improve the thermal and electrical properties of impregnated components, making it possible to assign them a higher thermal class to the impregnated materials, should they be compared to those same materials without impregnation.

Electromagnetic Concepts

It can be said that electric fields are located around a properly charged body and are represented by invisible lines of force representing an invisible electric field capable of causing phenomena related to attraction and repulsion. In the case of two bodies charged with equal charges being placed together, their electric fields must act accordingly in order to repel them, and if these two bodies are charged with opposing charges and placed together, their electric fields must work to attract them. In this way, the electrons found in the outer band of the atom are displaced by the application of any external force.

single phase baldor motors

Electrons that are charged to the outer side of their orbits may result in the absence of electrons in the atom from which they emerge, and an overload in the atom to which they migrate. However, the absence of the electrons can generate a positive charge, considering that a greater number of protons exist than electrons, and the excess of electrons, resulting in the creation of a negative charge. When it comes to electricity there is a popular saying that says opposites attract, it’s the same is proven true. Once electrically charged, all bodies come to possess a kind of invisible field around them.

Main Fundamentals and Definition of Electric Motors

Most components and electric motors perform their functions through the interaction between electromagnetic fields, even if machines based on different electromechanical phenomena can be found. Its fundamental principle of operation in which the electromagnetic motors refer is that there is a mechanical force along the entire wire at the moment it is conducting the electric current immersed in a magnetic field. The electric motor consists of a component capable of transforming electrical energy into mechanical energy.

Of all the types of machines found, it is seen as the most used for having the advantages of electric energy, such as hygiene, transport and simplicity of control, considering its simplified projection, great economy and high versatility of adaptation to different loads with optimized yields. In the case of the reverse task, capable of converting the mechanical movement into electric energy, it is generated by a generator or a dynamo. In the vast majority, the two components can differ only in their application and projection details. Traction motors found in locomotives perform both functions if the locomotive is equipped with dynamic brakes. https://www.mrosupply.com/motors/motor-accessories-parts/28025_bc143_baldor/

Starting Methods

It should be noted that all the starters found in the electric motors have a main circuit and a control circuit. The main or power circuit, as it may also be called, operates directly in the process of powering the motor, and in this way, it ends up having the main function of connecting the terminals and wires of the motor to the mains. In turn, the control circuit, as its name says, is to control the power circuit, thus determining when the motor can be turned on or off. Starters include protection devices such as fuse, thermal relay, circuit breaker and electric motor; control devices such as buttons, contactors and timers.

It is also important to emphasize the existence of signaling components, such as signal, voltmeter and ammeter. The motors are controlled by means of starters syncronous belts. The most used are direct, reversing starter, which works in the drive of small motors; star triangle starter, which acts in the drive of large motors that have no load; compensating match; which drives the big engines with load; and starting with frequency inverter, which operates on the drive of small and large motors.

Categories of Industrial Electric Motors

AC electric motors are industrial, and can be synchronous, asynchronous, three-phase and single-phase. The asynchronous type motor deals with a slip, according to the load intensity, however, most of the industries work with this type of component. Synchronous motors are generally more used in thermoelectric and hydroelectric plants. The synchronous name was given because the machine operates with rotational speed in constant synchrony with the frequency of the electric voltage oscillating.

AC motors also receive other types of classification, such as double-pole motors, because they can rotate at two different speeds in relation to their power, and double-spindle motor, which has only one output for each side. DC motors, also called DC motors, perform their functions with the aid of direct current. The components in it consist of a commutator ring, stator, brushes and rotor. The rotor has one or more bearings, which when energized produce a magnetic field. The magnetic poles inserted into the rotor field are attracted to the opposing poles generated by the stator.

Nominal Power Increase

The common transformers of two isolated windings could be connected as autotransformers and if we compare this procedure, we noticed that there was a considerable gain in the nominal power of the transformer when it was connected as an autotransformer.

This is a great advantage of this type of connection, because when connected as an autotransformer only part of the power going from the primary to the secondary goes through the windings. The other part will be transmitted directly through the electrical connection, which greatly increases the power transmission capacity from one circuit to another.

skf bearing spherical

When the SI power injected into the autotransformer primary is equal to the SO power dispatched by the secondary, we can verify that the autotransformer has high efficiency and low internal impedance, which reduces occasional power losses.

We will identify the internal apparent power transported from one transformer from the autotransformer to the other and that power will only identify the portion of the total power that was transmitted from the primary to the secondary through electromagnetic conversion. In this way, we obtain the same power transmitted by the conventional transformer before the connection as autotransformer.

The IEC 60034-2 standard

The IEC 60034-2 standard provides recommendations on measuring instruments and their accessories, which are the measurement transformers, shunts and bridges used during the tests. They must have a accuracy class of not more than 1.0% and instruments for determination of DC resistance of 0.5%.

The electric motor running with free rotor will produce the sum of the constant losses and the machine is fed at its rated voltage and frequency. The constant losses will be provided by the absorbed power, deduced from the Joule losses in the stator, since the Joule losses in the rotor will be ignored.

In the free-rotor test with rated voltage, the free rotor losses comprise losses in the iron and losses by dispersion, as well as losses due to the friction of the bearings, and also total loss by ventilation in the machine, including the power absorbed in the fan.

The motor rotation shall be evaluated by means of a digital tachometer and during the measurement of slip the synchronous speed shall be marked from the power frequency during the test.

The efficiency of the electric motor is obtained by the ratio of output power to total input power. The output power will be equal to the input power taking the losses. https://www.mrosupply.com/ac-motors/severe-duty-motors/701974_cecp84115t-5_baldor/

Protection Element

Fuses are considered as the most common elements used for protection against short circuits in electrical systems of electric motors. Its operation is based on the fusion of the fuse element, found inside it.

 

This element is nothing more than a simple conductor of a small cross section, which, in turn, passes, due to its high resistance, by a higher heating than the other conductors in the passage of the current.

The element consists of a wire or a blade, usually projected on materials such as tin, silver, lead or alloy, inserted into a closed porcelain body. It has an indicator, which has the function of verifying whether it has operated or not. It is a wire connected in parallel with the fuse element, which can release a kind of spring that acts on a plate or screw, usually attached to the body cap.

The fuses, in general, have a completely granular material in the interior of the fuse, with granulated extinguisher material. For this purpose, quartz sand of suitable granulometry is used.

The fuse element can be found in different forms. Depending on the nominal current of the fuse, it consists of one or more wires or blades in parallel, with some sections of reduced section. In it, there may still be a soldering point, in which the melting temperature will be much smaller, if compared to that of the element that acts for long duration overloads. https://www.mrosupply.com/motors/ac-motors/metric-frame-motors/26813_mvm5450c_baldor/

Gear Coupling

Gear coupling is necessary at times when it is necessary to reduce the speed. It is extremely important to observe if the axes are correctly aligned and parallel, in the case of straight gears, and in the engagement angle, in the case of helical or helical gears. Pulley and belt couplings are a specific type of transmission used when there is a need for a gear ratio between the motor and the driven load.

Tension that is excessive in the belts can damage the bearings and can cause the motor shaft to rupture. Motors equipped with sliding bearings must be coupled to the driven machine or by means of a gear unit. Sliding bearings do not allow coupling by pulleys and belts.

Motors that have sliding bearings can count with up to three marks on the end of the shaft, bearing in mind that the center mark is the indication of the magnetic center and the other two marks on the outside, The rotor.

Induction Motors – Three Phase and Single Phase

Three-phase and single-phase induction electric motors are the most commonly used by consumers in general, industrial, commercial and residential sectors. In the industrial and commercial field three-phase and single-phase motors are used, while in the residential sectors the most active has been the single-phase motor, due to the application and cost characteristics.

Single-phase induction motors have a higher cost than the three-phase induction motor osnw 32×5.7/16 skf, however, the cost of the three-phase installation is higher than the two-phase or single-phase installation. Today, there are several models of single-phase motors, for example: single-phase induction motors with capacitor start, starting at resistance, two-value capacitor and single-value permanent capacitor among others.

In the market there are only three-phase and single-phase induction motors, however there is a line of motors that is in the research phase, are the asymmetric induction motors asymmetrical fed by symmetrical biphasic voltage with return. These operate without the capacitors and centrifugal wrenches. Thus, the biphasic asymmetric return motor would have an advantage over single-phase motors, the lower cost. At first this motor would be used in the urban zone since it would need a biphasic voltage source with return.

What are Couplings for?

In electric motors the couplings are used for the transmission of torque for the coupled machine. When we use this coupling, we must check the items:

– Use correct tools to assemble and disassemble the couplings, avoiding damage;

– Maximum loads should not be exceeded as well as speed limits;

– Carrying out the leveling and alignment of the engine.

The direct couplings are the most varied, such as gear, pulleys and belts and sliding bearings. They are characterized when the motor shaft is coupled directly to the axis of the driven load, resulting in lower cost, greater safety against accidents and less physical space. Gear coupling is used whenever a speed reduction is required, where the shafts will be aligned, closely parallel and at the angle of engagement.

In turn the coupling by pulleys and belts is used when we need a ratio of speeds between the motor and the driven load. The coupling with sliding bearings must be coupled directly to the driven machine or coupled through reducer, not being possible the coupling by pulleys and belts. https://www.mrosupply.com/bearings/rod-end-bearings/male-rod-end-bearings/2261322_ctmdl-4y_sealmaster/

Alternating Current is used in many applications, especially in high power systems, industries and electrical machines, usually in electric induction motors that equip appliances such as electric kettles, refrigerators and washing machines.

The speed of AC electric motors is determined by the frequency of the power supply, which results in excellent conditions for its operation at constant speeds.

THREE-PHASE ELECTRIC MOTOR CONNECTION

Three-phase electric motor connection with cage rotor should be done in a direct way

Where possible, the starting of three phase electrical motor with squirrel-cage rotor must be carried out directly, i.e., at full voltage by means of a contactor. This is the simplest method and also more feasible, however, only when the starting current does not interfere directly in the electric motor power supply.

It is important to remember that the electric motor starting current induction reaches values of order of 6 to 7 times the rated current and, as the rated current is always a function of power, a situation it must be configured in the current is starting a relationship with the rated current of the network so that during the starting time and this current will not change the supply conditions of all consumers for higher voltage drop which is caused on the network.

This occurs when the electric motor px70 dodge power supply is strong enough and the current of the electric motor is negligible when considering the capacity of the network; can still occur when the electric motor starting is always made without load and with the starter reduction that will be tolerable to both other consumers falling momentary tension and when altered by the electric power utility in the region.
