An induction motor is comprised of a stator and rotor, with the stator featuring a 3-phase winding fed from a 3-phase supply. The rotor comes in two types - squirrel-cage and phase wound. The squirrel-cage rotor consists of heavy bars tightly pressed on the shaft, while the phase wound rotor has a 3

Induction motors are widely used in various applications due to their advantages like robustness, high power-to-weight ratio, and low cost. However, they have limitations such as fixed speed operation. These motors consist of a stationary stator and a rotating rotor, with different designs like squi
