The starting torque of a 3-phase squirrel cage induction motor is____________?
Correct answer: B. 1.5 times the full load torque
- A. twice the full load torque
- B. 1.5 times the full load torque
- C. equal to full load torque
Explanation
A conventional squirrel-cage induction motor is commonly specified as having a starting torque of about 1.5 times its full-load torque in standard textbook comparisons. The exact value varies with rotor design, so this is a typical rather than universal value.
