Vol. II - Alternating Current (AC) - Electronics Textbook

With direct current covered and understood it is now time to delve into the world of alternating current. Alternating current is when current flows in one direction for a set time, then changes direction, then changes back, and so on in a repeating cycle. The alternating motion is most commonly in ...

AC induction motors | How AC motors work - Explain that Stuff

Induction motors in practice What controls the speed of an AC motor? In synchronous AC motors, the rotor turns at exactly the same speed as the rotating magnetic field; in an induction motor, the rotor always turns at a lower speed than the field, making it an example of what's called an asynchronous AC motor.
