Question: A 2 5 0 V , 5 0 Hz , 1 1 0 hp , three phase induction motor is drawing 3 0 3 .

A 250V,50Hz,110 hp, three phase induction motor is drawing 303.701A at a 0.8 pf lagging. The stator copper losses are 9258.05 W, and the rotor copper losses are 7406.44 W. The friction and windage losses are 4536.45 W, the core losses are 1944.19 W, and the stray losses are negligible. Find the following quantities: (N.B. Remember that, in electric machines, the industry convention is that one hp is exactly 746 watts.)(N.B. For this problem, consider that the core losses appear as in a transformer in an Rc in parallel with jXm).(N.B.2. Remember that in a three phase equipment, the rated voltage listed above is line-to-line 250 V.)
