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

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.


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.


Single phase motor speed is determined by the?

frequency of the power supply it is connected to. The speed of a single phase motor is directly related to the frequency of the alternating current (AC) power supply. As the frequency of the power supply changes, the speed of the motor will also change.


Will it hurt 230 volt single phase motor plugged into 277 V single phase?

Yes, plugging a 230V single phase motor into a 277V single phase power supply can potentially damage the motor due to the higher voltage. It is recommended to match the voltage ratings of the motor and power supply to prevent any issues.


You have one hp three phase motor where as available power supply is only single phase how can you run this motor?

You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com


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.


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 is static converter can a power supply of computer is static converter?

A single phase supply can operate a three phase motor with a static converter. No a power supply of computer cannot be fed through the static converter.


Can a single phase motor be wired to a three phase soft start?

No, a single phase motor cannot be directly connected to a three phase soft start. A single phase motor requires a single phase power supply, while a three phase soft start is designed for three phase motors. Using the correct soft start for the motor type is essential for proper operation and protection of the equipment.


How is a three phase agricultural motor used when there is no power supply?

With no three phase power supply you can't use a three phase motor of any kind at all!


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 is the simplest way to run a 3 phase 380 V motor of about 1 KW directly on 220 V single phase supply without resorting to rewinding or frequency converters?

You cannot run a three phase motor on single phase power. You'll burn the motor up within minutes. By the way, I've never seen or heard of a 380 volt motor. Do you mean a 480 volt motor? If so, the only way you can power it is with the correct full voltage and a 3 phase power supply.
