A 3 phase, 6 pole induction motor is rated at 400hz, 150v, 10h.p., 3% slip at rated power output. The windage and friction loss is 200w at rated speed. With the motor operating at rated voltage, frequency, slip, and power output, determine
(a) Rotor speed,
(b) Frequency of rotor current,
(c) Rotor copper losses,
(d) Power crossing the air gap,
(e) Output torque.
Consider the circuit of Figure (a) and obtain the complete solution for the voltage v C (t) across the 5-F capacitor and the voltage v x (t) across the 5- resistor.
