ELECTRICAL BRAKING OF POLYPHASE INDUCTION MOTORS:- The most simple way to stop an induction motor (or any other type of motor) is to disconnect the terminals from the supply. Torque is no longer developed, and the combined effect of the rotor and external load brings the motor to rest. When rapid and more positive action is required, mechanical or electrical braking may be employed, but the latter has many advantages, particularly where precise control of the stopping moment and smoothness of operation and required. Following are the three main methods of electrical braking of induction motors :
