A wound rotor induction motor is preferred, as compared to squirrel cage induction motor, when major consideration is____________________?
Correct answer: B. high starting torque
- A. slop speed operation
- B. high starting torque
- C. low windage losses
- D. all of the above
Explanation
A wound-rotor induction motor allows external resistance to be added to the rotor circuit, producing high starting torque and controlled acceleration. Low windage loss is not the main reason for choosing it over a squirrel-cage motor.
