The condition for maximum running torque in induction motor is

Electrical Engineering XYZ MCQs

The condition for maximum running torque in induction motor is:

1. R = S.X/2
2. R = X/2
3. R = X
4. R = S.X

Correct answer: 4. R = S.X

Explanation: The condition for maximum running torque in induction motor is: R = S.X

This choice directly corresponds to the optimal balance where the rotor resistance equals the product of slip and reactance, maximizing the torque produced by the motor.
