Q.

Cogging of induction motors occurs at

  • AHigh voltage and when the number of stator teeth and rotor teeth are equal
  • BHigh voltage and when the number of stator teeth and rotor teeth are not equal
  • CLow voltage and when the number of stator teeth and rotor teeth are equal
  • DLow voltage and when the number of stator teeth and rotor teeth are not equal
Correct Answer : (C)

Low voltage and when the number of stator teeth and rotor teeth are equal

Hints :

Cogging of induction motors occurs at Low voltage and when the number of stator teeth and rotor teeth are equal.
