Induction Motor
Induction Motor
An induction motor is an ac motor that works on the principle of electromagnetic induction. The motor has two main components stator and rotor. The stator is a stationary part and consists of electrical windings which produce a rotating field when energized by an ac power supply. The rotor is a rotating part and consists of conducting bars or short-circuited windings that are placed in a rotating magnetic field of the stator.
As we know according to electromagnetic induction changing magnetic field induces current, so stator magnetic field induces a current in rotor conductors. Now these current-carrying conductor produces their own flux which in turn interacts with the flux of the stator thereby causing the motor to rotate. Induction motors are widely used in industrial applications such as pumps, fans, compressors, etc.
