The equivalent circuit per-phase parameters for a 220 V, 50 Hz, three-phase, star-connected, 4-pole, induction motor is: R1 0.22 0, R2' = 0.15 0. The inductor motor has a slip of 4% and the full load current has a magnitude of 61 A. The mechanical losses (windage and friction) and the iron losses are 610 W are 420 W respectively. The input power is 36300 W. Determine the following when the motor operates at full load at rated speed: A. the synchronous speed RPM B. the rotor speed in RPM C. the efficiency of the motor in percentage D. the output torque in N-m for a slip of 8%.
