An AC motor can be an electric engine driven by an alternating electric current (AC). The AC electric motor commonly contains two basic parts, an outside stator having coils given alternating current to make a rotating magnetic field, and an internal rotor mounted on the output shaft making a second rotating magnetic field. The rotor magnetic field could be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings.
Single-Stage AC Induction Motors & Gear Motors
AC induction motors are optimal for uni-directional and continuous procedure like a conveyor system. All you need is to connect a capacitor and plug the engine into an AC power supply and the motor could be easily operated.
