An AC motor is an electric motor which is driven by an alternating current (AC) as opposed to a direct current (DC). AC is the form in which electricity is delivered to our homes and premises, DC electric current is delivered from a battery.
The AC motor usually consists of two parts, an outside stationary housing which has coils in the form of a ring of electromagnets arranged around the outside (making up the stator), this is supplied with alternating current to produce a rotating magnetic field. The second part is an inside rotor, a solid metal axle, a loop of wire, a coil, a squirrel cage made of metal bars and interconnections, which is attached to the output shaft producing a second rotating magnetic field.
