This type of motor is designed to provide strong starting torque and strong running for applications such as large water pumps. There are a number of different construction methods used but the basic principle is the same. A shaded pole electric motor is a single phase induction motor provided with an auxiliary short circuited winding or windings displaced in magnetic position from the main winding. Capacitor motor single phase wiring diagrams always use wiring diagram supplied on motor nameplate. Click here to view a capacitor start motor circuit diagram for starting a single phase motor. Each component ought to be placed and linked to different parts in particular manner.
So before you start to wire your motor you need to be sure what type it is. Single phase motor wiring diagram with capacitor start.
