In 3 -phase induction motors, the relative speed of stator flux with respect to____is zero.

In 3 -phase induction motors, the relative speed of stator flux with respect to____is zero.

Right Answer is:

Rotor flux

SOLUTION

In a three-phase induction motor,

  • The stator is stationary, and the rotor is a rotating part
  • Both the stator field and rotor field rotate with synchronous speed
  • The rotor rotates with a speed less than synchronous speed
  • The relative speed between the rotor field and a stator is synchronous speed.
  • The relative speed between the rotor field and stator field is zero.
  • The relative speed between stator filed and stator is synchronous speed
