Insertion of resistance in the stator of an induction motor___________?
Correct answer: B. decreases the starting torque
- A. increases the load torque
- B. decreases the starting torque
- C. increases the starting torque
- D. none of the above
Explanation
Adding resistance in the stator causes a voltage drop, so the motor receives a lower voltage and its starting torque decreases approximately with the square of voltage. It does not increase the load torque demanded by the motor.
