Can a 3 phase motor be converted into a single phase motor?
Petermazambani
A three-phase motor will not start if one or two phases aren't connected. If while running one or two phases "drop out", it will continue to run for awhile, but will eventually burn out, unless connected to a motor saver.

∙ 13y agoSupplying power to a 3-phase motor using a single phase is termed "single phasing", which is, in general, not good for the motor. Depending on the connection, one phase or two phases will have higher than normal current draw, which could damage these legs. If lightly loaded, the motor might be fine.
You need to supply three phase power to a three phase motore for it to operate normally and be able to pull it's specified load. If all you have is a single phase, there are power devices made to give you three phase power from single phase.

What is the minimum voltage a 115vac 400hz 3 phase motor will run?
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.
What size motor do you need to run a compressor 2 stage 80 gallon tank i have a 3 phase on it and want to change motor?
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.
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.
Can you replace a three phase motor 3 Hp RPM 1420 with a single phase motor for a planer?
Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.
Can you run a 7.5 hp 3 phase motor on solar energy?
The output from solar panels is a d.c. voltage which, using an inverter, is converted into an a.c. single-phase voltage. So under normal conditions, the answer would be no.
Is 3 phase motor run on 1 phase supply?
No. That would be a single phase motor.
How do you connected 3 phase motor to single phase power?
Use VFD to make 3 phase from single phase source.
Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
What is the minimum voltage a 115vac 400hz 3 phase motor will run?
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.
How do you convert a 0.37kw 4 pole 3 phase motor to single phase?
The motor cannot be altered to work on single phase power. You will either have to put in a new single phase motor or use a phase convertor box. Do a google search for phase convertor - you will find plenty.
How do you convert or rewire a 20HP 3 phase motor to single phase motor?
The winding design of the motor will not economically allow this to work. You would have to drive a 3 phase generator to supply it.

How much more efficient is a 2 hp 240 v 3 phase motor compared to a 120 v single phase 2 hp motor?
I would guess it would use a third less than a single phase motor. The voltage differences don't save but 3 phase does. A 3 phase motor also starts easier.
Is it possible to convert a 2.4 kw single phase appliance to a 9kw 3 phase appliance?
No, it is not possible to convert a 2.4 kw single phase appliance to a 9kw 3 phase appliance. Single phase can not be converted to three phase with out considerable cost involved.
What are the advantages of three phase motor over the single phase motor?
A 3-phase motor produces a steady torque that does not pulsate. A 3-phase motor starts turning in the right direction when switched on without the need for a separate starting winding.
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.
How do you determine a 3 phase motor and each winding?
To see if the motor is three phase or single phase look at the motor's nameplate. There it will tell you what the voltage needs to be and what system phase the motor needs to be connected to operate properly.
