Hi everyone, I'm facing challenge at my work.
Can someone suggest me the fastest way to calculate a coil amount for rewinding motor but the condition is there's no nameplate, so we just know the diameter and phase angle of the motor. Or can you give me a reference recomendation about this?

Thanks:)

Determining the frame size is straightforward. You can count the poles. Voltage should be known. If you can determine the power required by the process, use the formula for a motor with the next higher power output and get fits in that frame.
