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.
