Advantages of three phase over single phase motors more energy efficient and have no capacitors or centrifugal switches to drive or maintain this guide will focus on three phase ac motors as they represent the majority of motors in use today.

Single phase electric motors have a capacitor connected in series with the run winding therefore the motor is always drawing a constant current irrespective of mechanical load. When the motor is not loaded driving this residual current is dissipated in the form of heat. The diagram shows a typical construction of a three phase motor with an open configuration ie. From the top left to the posts are labeled. I asked a spark yesterday about the terminals but he couldnt help as he only wires domestic and has never touched motors.

It is 110 volt with a start and run capacitor already wired from motor. It is a two capacitor startrun motor but the terminals are marked u1u2v1v2w1w2 etc. The motor is not configured for star or delta configuration and all three phases are isolated.
