Q2/A// A 6-pole, 50 Hz, 3-phase induction motor has a rotor resistance of 0.24 2 per phase and runs at 950 rpm at full-load. A maximum torque of 15 Nm at 880 r.p.m and the stator impedance is assumed to be negligible. Calculate: (a) The full load torque and power factor. (b) The resistance to be added to the rotor circuit to obtain 60% of the maximum torque at starting.
