No, a three phase motor cannot generally be wired to a single phase supply so, to run it on single phase you would need an electronic inverter unit or a rotary phase converter to generate the three phase supply. Such invertors or convertors are generally expensive to buy and the price will depend on the power of the motor.

As long as the power requirements of the equipment that you want to use the motor on are not too high for the biggest single phase motor available, it is usually best to see if you can part-exchange the three phase motor for a suitable single phase motor.

Another answer

Some three phase motors have all their windings brought out to terminals, usually two terminals per winding. So, if the motor has at least six terminals inside its wiring connections box and you can find out for sure that it was designed to be rewirable to run on single phase as well as on three phase - from the manufacturer or a qualified electrical engineer - then you should be able to connect them to run the motor on a suitably sized single phase circuit.

("Suitably sized" means that the circuit breaker and wiring is of the correct size to handle the current needed by the motor.)

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

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.


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 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 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.


Can a single phase supply be used in a three phase supply?

A three phase supply can provide three single-phase outputs.


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.


How can you run a 200 volt 3 phase motor on 230 volts single phase?

You can not run a three phase motor on single phase Source. You can use a VFD (variable frequency drive) or a rotary phase converter to supply your three phase motor from a single phase source. For large motors it can be expensive.


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


Can you run a three phase motor with single phase generator with help of phase converter?

Terminology gets misapplied but a 3-phase converter produces a 3 phase supply from a single phase supply. The only proviso is that generator, converter and motor are all suitably rated and compatible.


Is house current fit for single or three phase motor?

House current is single phase.AnswerIt depends on the system supplying your residence. Most are single phase, but some, such as here in Cyprus, have a three-phase supply as standard.


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.


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 are the disadvantages of a two phase AC motor over a three phase and single phase AC motor?

The main drawback is that two-phase systems are archaic, and you are unlikely to find one with which to supply a two-phase motor.


Can you connect a 3 phase motor to a 1 phase supply?

No. You need a three phase supply to run a three phase motor. If you only have a one phase supply, you could use an inverter or a motor-generator set, but by the time you did that, it would have been more cost effective to simply get a one phase motor, or (in the bigger case) upgrade to a three phase supply.


What circuit you can use to run three phase motor?

It must be a three phase supply service to run a three phase motor.


How does a three phase motor work on a two phase power supply and how do you wire it up?

A three phase motor will not work on a 2-phase power supply, it needs a 3-phase power supply. Two phase electrical services are no longer the standard for electrical distribution. You would need to get an expensive phase-changer to convert your normal single phase power supply to three phase. Depending on the power output you require from the motor, it can often be much cheaper to buy a suitable single phase motor, new or secondhand, instead of buying a phase-changer as the power supply for a three phase motor. If you really do want use that three phase motor you may find it worthwhile to contact your electricity supplier first, to ask if they can install a three phase service for you to use and what the cost would be. Otherwise, after you have bought the expensive phase-changer unit, you may find out later that your electricity supplier could have upgraded your service to three phase for a lower cost!


How do you reverse a 3 phase motor to single phase?

If you are asking whether you can connect a three-phase motor to a single-phase system, then the answer is no.


Can two phase legs on a three phase system be used for single phase load?

The wire can be used for dc or any number of phases provided it's thick enough to take the current you need. &lt;&lt;&gt;&gt; Any two legs of a three phase system can be classed a single phase. As long as the voltage required by the load is supplied by the supply it can be connected. A perfect example of this is on a 120/208 volt supply. This is a three phase supply allowing three phase 208 volt motor to be connected to it and also by using any two legs of the supply, a single phase 208 volt motor can also be connected.


Can you change 3 phase compressor to single phase compressor?

If you are referring to an air compressor motor then yes. A single phase and three phase motor can be interchanged. They have to have the same horsepower though because the compressor manufacturer has calculated the needed HP to turn the compressor over. You may need to rewire for the single phase motor unless the single phase voltage is the same as what the three phase voltage was. If this is the case just use two legs of the three phase voltage supply. The overload protection will have to be changed to reflect the higher current used by the single phase motor.


How do you convert a three phase power supply into single phase power supply?

Any two legs of a three phase supply are classed as single phase. L1 - L2, L2 - L3 and L3 - L1.


Does a transformer play a vital role in connecting a three phase motor to a single phase power supply?

To do this, you will need to phase shift the single phase power supply into three distinct phases that are 120 degrees out of sync with each other. Phase shifting transformers can be used for this, but there might be other ways as well.


How is it possible that a Chicken Rotisserie that uses 208v 3 phase can have a motor that uses 208v 1 phase?

Two scenarios are that the motor could be a three phase motor. These three phase motors are manufactured in smaller sizes. The other scenario is that the motor is a 208/220 volt single phase motor. It will operate on 208 volts by taking two legs of the three phase supply for its operation.

No.


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.
