Question

In the running condition of 3 phase slip ring Induction Motor *what will happen

Answer 1

Answer:

Some voltage shall be induced in the rotor, but rotor current will remain zero, because rotor is open circuited. As there is no rotor current, there will not be any torque developed, and hence no rotation of rotor. Stator current will be small fraction of the rated motor current, hence it will not harm the motor.
