PM-P297 THREE PHASE SLIP RING INDUCTION MOTOR (MOTOR)
The three phase induction motor is the most widely used electrical motor. Almost 80% of the mechanical power used by industries is provided by three phase induction motors because of its simple and rugged construction, low cost, good operating characteristics, the absence of commutator and good speed regulation. In three phase induction motor, the power is transferred from stator to rotor winding through induction. The induction motor is also called a synchronous motor as it runs at a speed other than the synchronous speed.
Like any other electrical motor induction motor also have two main parts namely rotor and stator.
The rotor of the three phase induction motor are further classified as
