A 50 hp, 440 V, 60 Hz, three-phase, Y-connected induction motor has the following equivalent circuit parameters: R, = 0.1 Q R 0.12 Q = 2150 W X, = 0.35 Q X, 0.42 %3! With no load, the line current is 18 A at 0.089 p.f. lagging. If the motor speed is 1755 rpm, determine a. the line current; b. the developed torque; the output power (may be different than rated output); and, d. the efficiency.
