A three-phase, 60 Hz, six pole, wound rotor induction motor draws 10kw when driving its normal load. It draws 700 W when the load is diconnected. The rotor and stator copper losses under normal load are 295 W and 310 W respectively. calculate the effieciency, the speed, and the shaft torque of this motor under normal load conditions. Assume equal rotational can core losses and negligible no-load copper losses.
