A three-phase, two-pole, 400-V (per phase), 60-Hz induction motor develops 37 kW (total) of mechanical power Pm at a certain speed. The rotational loss at this speed is 800 W (total). (Stray-load loss is negligible.)
a. If the total power transferred to the rotor is 40 kW, determine the slip and the output torque.
b. If the total power into the motor Pin is 45 kW and RS is 0.5 ? , find IS and the power factor.
