Main Page | See live article | Alphabetical index Shaded-pole synchronous motors are a class of AC motor that uses single phase electric power to convert electric power to mechanical energy. They work by using a squirrel-cage rotor and a split stator that has copper shorting rings placed on it so as to shade a portion of the stator's magnetic field enough to provide starting torque.
