Three-Phase Induction Motor – Construction, Working, Types and Applications
What is a 3-Phase Induction Motor? A three phase induction motor is a type of AC induction motors which operates on three phase supply as compared to the single phase induction motor where single phase supply is needed to operate it. The three phase supply current produces an electromagnetic field in the stator winding which leads to generate the torque in the rotor winding of three phase induction motor having magnetic field. Construction of Three-Phase Induction Motor The construction of an induction motor is very simple and robust. It has mainly two parts; Stator Rotor Stator As the name suggests, the stator is a stationary part of the motor. The stator of the induction motor consists of three main parts; Stator Frame Stator Core Stator Winding Stator Frame The stator frame is the outer part of the motor. The function of the stator frame is to provide support to the stator core and stator winding. It provides mechanical strength to the inner parts of the motor. The frame has fin
