Answer:
Usually we operate motor at slip in the range 0.04 ~ 0.06, thus for a stator frequency of 50 Hz , rotor frequncy is around 2~3 Hz. As core losses are proportional to square of frequency(Eddy current losses) or proportional to frequency( Hysteresis losses) , therefore the value of the Core loss is negligible for roto
