1. A six-pole, three-phase, 440-V, 60-Hz induction motor has the following model impedances:

RS = 0.8 Q XS = 0.7 Q RR = 0.3 Q XR = 0.7 Q Xm = 35 Q

Calculate the input current and power factor of the motor for a speed of 1,200 r/min.

2. An eight-pole, three-phase, 220-V, 60-Hz induction motor has the following model impedances:

RS = 0.78Q	XS = 0.56 Q	Xm = 32Q
RR = 0.28Q	XR = 0.84 Q

Find the input current and power factor of this motor for s = 0.02.
