Athree-phase,wye-connected, 220-V, 10-hp, 60- Hz, six-pole inductionmotor (using Figure 13.2.6 for notation) has the following parameters in ohms per phase referred to the stator: R1 = 0.294, R 2 = 0.144, Xl1 = 0.503, X 12 = 0.209, and Xm = 13.25. The total friction, windage, and core losses can be assumed to be constant at 403W, independent of load. For a slip of 2.00%, compute the speed, output torque and power, stator current, power factor, and ef?ciency when the motor is operated at rated voltage and frequency. Neglect the impedance of the source.
