A 6 pole 50 Hz 3 phase induction motor running on full load develops a useful torque o 160 Nm when the rotor emf makes 120 complete cycles per minute Calculate the shaft power output If the mechanical torque lost in friction and that for core loss is 10 Nm Compute a the copper loss in the rotor windings b the input to the motor and c the efficiency The total stator loss is given to be 800 W
