Q.

Crawling in an induction motor is due to

  • ATime harmonics in supply
  • BSlip ring rotor
  • CSpace harmonics produced by winding currents
  • DInsufficient starting torque
Correct Answer : (C)

Space harmonics produced by winding currents

Hints :

Crawling in an induction motor is due to Space harmonics produced by winding currents.
