A 440-V 50-Hz two-pole Y-connected induction motor is rated at 75 kW. The equivalent circuit

parameters are:

R1 = 0.075Â Î© R2 = 0.065 Î© X M = 7.2 Î©

X1 = 0.17 Î© X 2 = 0.17 Î©

Pcore = 1.1 kW PF&W = 1.0 kW Pmisc = 150 W

For a slip of 0.04, find:

(a) The line current

(b) The stator power factor

(c) The rotor power factor

(d) The stator copper losses

(e) The air-gap power PAG

(f) The power converted from electrical to mechanical form

(g) The induced torque

(h) The load torque

(i) The overall machine efficiency

(j) The motor speed in revolutions per minute and radians per second
