In the electrical trade it is called control voltage. This voltage can be any voltage. In North America the common control voltage is 120 volts.

What is the reason for starter motor burning?
When A Starter Burns Up, It Is Because Of Low Voltage While Trying To Crank The Engine. When Voltage Drops...Amperage Goes Up And Usually Melts The Copper Winding In The Starter Or Armature.
How much KW range can be use star-delta starter?
The use of a star delta starter is for motor control only and not resistive heating loads. This type of starter is used to dampen the inrush current by using a lower voltage to start the motor.
What size of contactors used for 20hp star-delta starter?
The size of the contactors are dependant upon what the voltage the motor is operating on.
What is a soft starter?
A soft start is a starter that bring a motor from the starting point of a slow speed in to a multiple speed that can be programmed in the starter Imagine you have a big plant in your factory, the voltage will go down/up when the plant start/stop, cause the sharp start/stop The soft starter is controlling AC motor in soft start/stop to eliminate such problems.

What will happen if induction motor is in star-star connected?
If a motor is connected in a star configuration it will operate at a slower speed. This is the working process that a star delta starter operates on. At first through the starter the motor starts in the star connection. When the motor gets up to its highest speed in that connection it times a timer out , the star starter drops out and the delta starter pulls in and then connects the motor in the delta connection. This allows more voltage to be applied to the motor and it then speeds up to its nameplate rated RPM.
Can a voltmeter be used to measure voltage in and out of a starter motor?
Voltage flow into a starter motor, never out of it. Use the voltmeter to measure the voltage at the starter motor before starting to crank and then whilst it is cranking. (Before cranking, the voltage appears across the starter motor relay only.)
What is the purpose of dol starter in three phase motor?
Three phase motors are controlled by a device called a starter. The starter allows the motor's supply voltage to be applied to and removed from the motor. These types of starters coil's can be controlled with usually a lower voltage that can be remotely controlled.
What is direct online motor starter?
As the name recommends, Direct-On-Line beginning implies that the Motor is started byassociating it straightforwardly to the supply at appraised voltage. DOL Motor Starter is reasonable for stable supplies and mechanically firm and very much dimensionedshaft frameworks.
Which part of a car supplies energy to turn the starter motor?
The battery
What is meant when the nameplate reads DC motor?
It means that the voltage that supplies the motor has to be a direct current source.
What is the difference between a motor starter and a contactor?
Motor started will have overloads the contactor connect es line voltage.
Is it common to have to replace a starter in a 1997 Nissan Sentra immediately after replacing the alternator?
Sometimes; if you operated the vehicle for some time with low voltage it could destroy your starter. Low voltage is the worst enemy of a starter motor.

Where is the starter relay on a 97 ford escort lx?
A 97 lx doesn't have a starter relay. The relay is built into the solenoid of the starter motor itself. It uses light voltage to transfer the power from the main cable to the starter motor itself.
How much voltage does star-Delta starter give to motor at start?
A delta starter supplies what ever the supplied voltage to the line side of the contactor is. The inrush current is usually 300% of the full load amperage of the motor. Edit to above answer: Actually the question is for a Wye-Delta Starter (Wye=Star). There are two contactors, one in Wye configuration and one with Delta. The Wye is used to start and the Delta for run. This is a reduced voltage start scheme. Though the line supply voltage remains the same, for instance 480VAC, the phase voltage at the motor will be different for the Wye: V(phase) = V(line)/1.732 In a Delta V(phase) = V(line) So the Phase Voltage during the start will be 277VAC and then when the motor is spinning, usually after a set time delay, the Wye contactor drops out and the Delta contactor kicks in so that Phase Voltage is now the full 480VAC.
