Introduction An induction motor or asynchronous motor is a type of alternating current motor where power is supplied to the rotor by means of electromagnetic induction. An induction motor is sometimes called a rotating transformer because the stator (stationary part) is essentially the primary side of the transformer and the rotor (rotating part) is the secondary side. Unlike the normal transformer which changes the current by using time varying flux, induction motors use rotating magnetic fields to transform the voltage. The primary side's current creates an electromagnetic field which interacts with the secondary side's electromagnetic field to produce a resultant torque, thereby transforming the electrical energy into mechanical energy. The polyphase induction machine has very peculiar characteristics that do not exist in any other machine types. There exists a value for induction machines called the slip which is a value that is based on the speed of the machine relative to its synchronous speed. Depending on the value
