Q1) A 460-V, 25-hp, 60-Hz, four-pole, Y-connected induction motor has the following impdances in
ohms per phase referred to the stator circuit:
R1 = 0.641 Q, X1 = 1.106 2, R2' = 0.332 2, X2' = 0.464 2, Xo = 26..3 Q
The total rotational losses are 1100 Wand are assumed to be constant. The core loss is Jumped in with the
rotational losses. For a rotor slip of 2.2 percent at the rated voltage and rated frequency, find the motor's
1) Input current & Efficiency
2) Sketch the complete torque-speed characteristic of an induction machine and indicate the three
modes of operation.
