There actually is no such thing as 2 phase. You either have single phase (As most/all residential services), or three phase (primarily in commercial/industrial). When a normal three phase motor 'loses a phase' (blown fuses, open winding, bad contactor, etc...) if it continues to operate, it is considered 'single phasing'. While such operation is typically only briefly. (They usually don't run long) While it probably will not operate very long, the motor would over heat, and loose speed rapidly, and they will sometimes make noise. If you need to operate a three phase motor on residential service, you will need a 'three phase converter' (some people call them 'inverter's) to electronically convert single phase power into three phase, but they are usually only practical for smaller three phase motors.

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.


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.


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 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.


What will happen if you change Phase and neutral connection to single phase motor?

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!

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.


Is 3 phase motor run on 1 phase supply?

No. That would be a single phase motor.

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.
