8. Determine the parameters of the equivalent circuit of a 3-phase induction motor from the following test results: No-load test: 400V, 9.5A, 1400 W Block-rotor test: 200V, 50A, 7000W. Neglect core-loss resistance. Assume per phase stator resistance is equal to per phase rotor resistance.
- 13. The shaft output power of a 3-phase, 50 Hz induction motor is 20 kW at 1440 rpm. Total stator copper losses are 650 W and stator core losses are 720 W. Friction and windage losses amount to 12% of shaft output power. Determine the rotor and stator input.
