Question:  A 230V, 60Hz, 6-pole, Y-connected three-phase induction motor has the following parameters in ohms/phase as referred to the stator:

R1 = 12.5Ω, R2=28.6Ω, X1=21.3Ω, X2=13.6Ω, Rc = 4200Ω, and Xm = 1800Ω.

The friction and windage loss is 3% of the power developed. If the motor speed is 1120 rpm, determine (a) power input, (b) the stator Cu-loss, (c) the rotor Cu-loss, (d) the air-gap power, (e) the power developed. (f) the shaft torque and (g) efficiency.
