Slip ring motor is preferred over squirrel cage induction motor where___________?
Correct answer: A. high starting torque is required
- A. high starting torque is required
- B. load torque is heavy
- C. heavy pull out torque is required
- D. all of the above
Explanation
A slip-ring motor permits external rotor resistance to be added during starting, allowing high starting torque with controlled current. This is why it is selected for loads requiring high starting torque rather than a standard squirrel-cage motor.
