Induction Motor: Construction, Working principle & Advantages
It is because of the low cost, simple and rugged construction of the motor. Moreover, it has good operating characteristics with an efficiency as high as 90%. An induction motor does not have any commutator, like the one we saw in a DC motor. Hence it provides a good speed regulation without any sparking.Related Post: Servo Motor Types, Construction, Working, Controlling & Applications; Working of Single-phase Induction Motor. Single-phase AC supply is given to the stator winding (main winding). The alternating current flowing through the stator winding produces magnetic flux. This flux is known as the main flux.Single-Phase Induction Motor Construction, Working and
