Thus we see that InductionMotoris self-starting. It does not require nay external mean to rotate. Now we consider a 3-phase synchronous motor.Why 3-Phase Induction Motors are Self-Starting but 3-PhaseSee all results for this questionWhat are the braking methods of an induction motor?What are the braking methods of an induction motor?Plugging induction motor brakingis done by reversing the phase sequence of the motor. Plugging braking of induction motor is done by interchanging connections of any two phases of stator with respect of supply terminals. And with that the operation of motoring shifts to plugging braking.Induction Motor Braking Regenerative Plugging DynamicSee all results for this question Speed control methods of induction motor | electricaleasy As induction motors are widely being used, their speed control may be required in many applications. Different speed control methods of induction motor are explained below. Induction motor speed control from stator side 1. By changing the applied voltage: From the torque equation of induction motor, Various Induction Motor Speed Control Methods| Advantages Jan 09, 2017The speed of induction motor can be varied by changing supply voltage. The torque developed in this method is proportional to the square of the supply voltage. T ∝ V2. This is the cheapest and easiest method, but it is rarely used because of the below reasons. A small change in speed requires a large change in voltage.
