Q.

The rotor slots are slightly skewed in squirrel cage induction motor to

  • AIncrease the strength of rotor bars
  • BReduce the magnetic hum and locking tendency of rotor
  • CEconomize on the copper to be used
  • DProvide case of fabrication
Correct Answer : (B)

Reduce the magnetic hum and locking tendency of rotor

Hints :

The rotor slots are slightly skewed in squirrel cage induction motor to Reduce the magnetic hum and locking tendency of rotor.
