_______________has the least value of starting torque to full load torque ratio?
Correct answer: C. Squirrel cage induction motor
- A. D.C. shunt motor
- B. D.C. series motor
- C. Squirrel cage induction motor
- D. Slip ring induction motor
Explanation
A squirrel-cage induction motor has relatively low starting torque because its rotor resistance is fixed and usually small, giving a low starting torque-to-full-load torque ratio. A DC series motor and slip-ring motor can produce much higher starting torque.
