A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

Since AC induction motors have been established as the preferred choice for industrial motors and the need for reduced power in all aspects of design is ever present, the efficiency of these motors is ...

In this single phase induction motor, energy from the primary winding in yellow is coupled through a magnetic core to a rotary structure called a bobbin, which acts as a short circuited transformer ...
