What happen when single phase supply of induction motor interrupted while driving the load?

That happens when the supply is turned off, and the motor runs down and stops.


What will happen if dc supply is given to shunt dc motor?

It will drawn a large amount of current which can destroy the shunt


What size inverter in watts is needed to run a 1.5 horsepower motor?

To answer this question, the voltage whether the supply is single or three phase, of the 1.5 HP motor must be given.


Which A motor is to be operated from 230 V 50 HZ single phase AC?

All types of motor can be run from a single-phase supply provided the frequency, voltage and power capacity of the supply matches that of the motor and it has been designed to run on single-phase.


When you supply mechanical energy as input to the motor what will happen?

Then the motor will act as generator by principle


Working principle of single phase induction motor?

the working principle of single phase induction motor is similar to the three phase induction motor, when we supply is given to the single phase induction motor a revolving field set up in the stator which produces a torqe air gap between north pole and south pole and rotor picks up speed


Is 3 phase motor run on 1 phase supply?

No. That would be a single phase motor.


What will happen if you interchange the supply legs of a three phase motor?

If you interchange any two of the supply legs of a three phase motor, the motor will operate in a reversed rotation than is did before the interchanging of the supply legs.


What is a static converter?

A static converter allows a single phase supply to operate a three phase motor. Basically it converts the single phase supply into enough energy to power the three phase motor.


How do you wire a three phase motor with two speed to a single phase power supply?

A three phase motor requires a three phase power supply. You can not run a three phase motor on a single phase power supply unless you provide some kind of converter, such as a motor-generator set or an inverter. You might be able to get the motor to rotate on single phase, if you provide starting torque somehow, but you will not get rated power in that configuration.


What will happen if neutral wire is not connected to a single phase motor and powered on?

The single phase motor when powered on when the neutral wire is not connected is that the motor will not start.


How do you start a three phase motor to a single phase power supply?

You don't. A three phase motor will not start unless it is connected to a three phase supply.


What happens when an ac motor is given dc supply?

it burns thats it


Why synchronous motor called double excited motor?

AC and DC supply sources we are given to motor so we are called double excited motor


What will happen if you will give ac supply to dc shunt motor?

it will not work.


What is the difference between a one phase and a three phase motor. And if a three phase motor is given a single phase supply will it run or not?

The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.


Why doesn't a shunt motor operate on a single phase AC supply?

Shunt motors do operate on single phase AC. There are millions, if not billions of them worldwide running right now.Make certain your voltage supply is correct for your motor. Also, make certain you're providing the proper amperage. Make sure it's not a three phase motor. (three phase motors won't operate on single phase power.) If your supply voltage and amp supply is correct and the motor still doesn't run, you've got a bad motor.


What happen if connect 3 phase supply to single phase motor?

I'm not sure how you would even accomplish this. On a single phase motor you will have the wire for connecting power to the motor, and a return neutral (along with several other wires for other things). If you connect two phases together you create a short and you'll blow the upstream fuse/breaker.


What happend when three pase motor will be start by a single supply?

Hmmm . . . do you smell smoke?


What must happen for an electric motor to spin?

suitable winding and correct power supply


Why you use only single phase induction motor not other?

You would use a single-phase induction motor if the available electric power supply is a single-phase one. That applies to the average house or small business.


What will happen if a 115v single phase capacitor motor connected to 230 v single phase supply?

Most likely is going to explode. Put 120 psi on a car tire rated for 35psi and you will have the same effect.AnswerThe circuit's protective device will disconnect the motor from the supply, It will not explode!


How do you use a one phase motor in place of a three phase motor?

To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.


What will happen when the shunt motor is connected across the supply line directly?

If the motor is designed for 120V or 220V whatever the case, it will function properly.If it is a 12V motor and you supply 120V it will make a mess and you will probably get hurt from flying debris!


What happens when ac supply is given to dc motor vice versa?

What is the meaning of Vice-versa?
