A 60-Hz, four-pole, Y-connected induction motor is connected to a 200-V (line to line), three-phase, 60-Hz line. The equivalent circuit parameters are
RS = 0.48 ? Rotational loss torque = 3.5 N-m XS = 0.8 ? RR = 0.42 ? (referred to stator) Xm = 30 ? XR = 0.8 ? (referred to stator) The motor is operating at slip s = 0.04. Determine the input current, input power, mechanical power, and shaft torque (assuming that stray-load losses are negligible).
