The starting torque of a squirrel-cage induction motor is___________?
Correct answer: A. low
- A. low
- B. negligible
- C. same as full-load torque
- D. slightly more than full-load torque
Explanation
A conventional squirrel-cage motor has relatively low starting torque because its rotor resistance is low. Double-cage and deep-bar designs improve starting torque by providing higher effective rotor resistance during starting.
