An 8-pole, 3-phase, 50 Hz induction motor is running at full load with a slip of 5 %. The rotor is star connected and its per phase resistance and standstill reactance are 0.35 1 and 2 1 respectively. The EMF between slip rings is 150 V. Determine the rotor current per phase and rotor power factor. Assuming the slip rings are short circuited.
