What is a single-phase motor? A single-phase motor is an electrically-powered rotary machine that can turn electric energy into mechanical energy. It works by using a single-stage power. They contain two types of wiring: warm and neutral. Their power can reach 3Kw and supply voltages vary in unison.
An individual phase induction motor consists of a single stage winding on the stator and 
a cage winding on the rotor. Whenever a 1 stage supply is connected to the stator winding, a pulsating magnetic field is usually created. In the pulsating field, the rotor will not rotate because of Single Phase Electric Motor china inertia.
