Unlike an asynchronous AC motor, a synchronous AC motor rotates at the same speed as the frequency of the AC power supply. In order to achieve this, the synchronous AC motor must be synchronized with the power supply using a feedback system. Read more..

generators transform mechanical energy into electrical energy. The mechanism involved is similar to that of an alternator.. Read more..

Alternating current (AC) is an electric current that reverses direction periodically. This means that the voltage of an AC signal also reverses direction periodically.

The frequency of an AC signal is the number of times per second that the current or voltage reverses direction. Read more..
