The thickness of stator laminations of a 3 phase induction motor, when compared to its rotor laminations, is: Correct Answer Less

  • The stator is stationary, so it has no need to be very strong because it can be mounted on a frame.
  • The eddy currents formed by the alternating current are controlled by using lamination. The more laminations, the better the control.
  • A rotor has to be strong to stop flexing, and very thin laminations are not suitable.
  • So, the rotor core is also built of sheet steel laminations, just like stator.
  • The frequency of the rotor flux is very low, as a result, thicker lamination can be used without excessive iron losses.
