AC motors also known as alternating current motor.  They include synchronous, servo, universal, inductionand single/multiphase types.  The advantage of using an AC motor compared to a DC motor would be minimized cost and they are particularly well suited for constant-speed applications. The most widely chosen AC motor would be either a synchronous or induction AC motor.
