A 500-V. 50-hp. 60 Hz. four-pole. Y-connected induction motor has the following impedances in ohms per phase referred to the stator circuit: Rt = 0.9 ohm XI = 1.1 ohm RI = 0.4 ohm XI = 0.5 ohm XM = 25 ohm The total rotational losses are 1100 W and are assumed to be constant. The core loss is lumped in with the rotational losses. For a rotor slip of 2 percent at the rated voltage and rated frequency. find the motor's (a) Speed (b) Stator current (c) Power factor (d) Pcony and Pout (e) Tind and Tload (f) Efficiency
