The physical internal windings between single phase and three phase motors makes this an impossibility That being said money can make anything happen. Depending on the amount of money you want to spend to make this happen there is a device on the market called a VFD ( Variable Frequency Drive). On the three phase input terminals you apply your single phase voltage. On the output terminals you connect your three phase motor. When run in this configuration there is an internal switch that has to be changed to let the VFD know that it should be looking for only two lines on the input to be hot. Otherwise the VFD thinks that there is a line loss on the three phase input terminals and the unit will not start. <<>> You can make a phase converter with a couple extra motors. Wire up a 120V single phase motor and couple it to a 3 phase motor. This turns the 3 phase motor into a generator for you to run to whatever equipment the 3 phase motor is. Although if you had a single phase motor you probable don't need a 3 phase motor. == == <<>> yes! you will have to buy a phase converter. <<>> yes, it is possible to this with a rotary phase converter . one manufacturer is "phase master" (as an example only, not wishing to promote any brand). these are not cheap units and it may be more cost effective to purchase a single phase (220V.) replacement motor . the overall efficiency (operational costs) would be better too . a rotary phase converter is usually the "last choice on the list" .

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.

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.

What household current do you need to power 460 volt motor?

There is no household current with which you can power a 460 volt motor.Normal US household power is 120/240VAC split phase. (Other countries have different configurations, but the answer remains the same.) Without a transformer, and a substantial power flow, you are not going to develop the voltage necessary to run a 460 volt motor. Even if you could generate that voltage, you still only have one phase available, and most 460 volt motors require three phase power.You could do this with an inverter, or a motor-generator set, but to be blunt, you are asking about a commercial application, not a household application.


Is 3 phase motor run on 1 phase supply?

No. That would be a single phase motor.
