I suggest you consult the manufacturer or a motor specialist as mistakes must not be made. Sometimes the wiring diagram is printed on the underside of the terminal box. The wiring of multispeed motors can be complex and it is wise to take no chances.

SOURCE: wiring a 220v single phase motor and capacitor

Black and white are usually power. an ohmmeter will confirm. Brown are for capacitors. There is almost always a diagram on the motor someplace. Eric

SOURCE: I wish to rewire a single phase electric motor

The motor itself should have a sticker which describes the wiring for 115. It is a small change involving a single wire moving from one pole to another inside the motor starter cap (the bump on the motor itself).

SOURCE: hobart model 5801 meat saw conversion from 3 phase

No, you need a new motor or a converter, but in the case of one saw, it wouldn't be worth the conversion. Just find an old single phase motor that will fit height wise and you should be all set. The speed is the same, the direction can be switched and the HP should not matter much, 1/2 , 1, depends on what you find out there. They all should cut wood no problem. Hope this helps.

De 3/4 hp motor si es trifasico omonofasic0 cuantas revoluciones 1400 o2800

ENGLISH ONLY please. We are a North American Website

Translated:
3/4 HP motor if it is three-phase or single-phase how many revolutions 1400 or 2800
==========================================
Phases are irrelevant. A motor is made for a specific speed and for a single voltage. It can be made to be 1,200 RPM or 10,000 RPM depending on the windings and the magnets. The information plate on the motor will tell you the specifications, voltage, phase, amps and speed.

I purchased a 3 phase electric motor by mistake. but i needed a single phase, anyway to wire it down?

You cannot make a 3 phase motor into a single phase motor.
You could, ( as you suggested), buy a single phase to 3 phase inverter. Even a 'variable speed drive' VF (variable frequency drive) inverter for greater flexibility, but depending on the size and purpose of your motor the cost might prove to be prohibitive.

I NEED TO REWIRE A DOERR LR24684 ELECTRIC MOTOR,ITS 1/2 HP, RPM 1725 115 volts to a metal lathe AND ON SWITCH IT'S WRITE- FOR IN DOWN IN CENTER STOP AND UP REV -I SEARCH TO CONNECT THIS...

Motor terminal box sometimes has a connection diagram inside the lid.

Basically a single phase induction motor has a run winding and a start winding and to reverse the direction the connections to one winding, usually the start winding, must be reversed and that is the function of the lathe switch.

Single phase motors are easily damaged and so if any doubt exists I strongly suggest you ask a motor specialist for assisstance.

Have a 3 phase compressor model vr5-8 want to know if it can be converted to single phase 230 volt and how

A 3phase motor cannot be rewired to run on single phase power. You need a phase converter. A 3-phase motor will only run on 3-phase power, and a phase converter will convert single phase power to 3 phase. Just google phase converter. There are two basic types, electronic and rotary. The rotary type are more powerful and efficient, but lot's more expensive than the electronic ones. Your only other option is to replace the motor with a single phase motor. Good luck.
