A 209-V, three-phase, six-pole, Y-connected induction motor has the following parameters: R1 = 0.128 12, R'2 = 0.0935 12, Xeg =0.49 12. The motor slip at full load is 2% and the load is of a fan-type. Assuming that the supply frequency is reduced by 20% and the v/f ratio is kept constant, calculate the following: 1) Motor speed 2) Starting torque 3) Starting current 4) Motor efficiency (ignore rotational and core losses)
