A ¼-hp, 230-V, 60-Hz, four-pole, single-phase inductionmotor has the following parameters and losses: R1 = 10 , Xl1 = Xl2 = 12.5 ,R2 = 11.5 , and Xm = 250 . The core loss at 230 V is 35 Wand the friction and windage loss is 10W. For a slip of 0.05, determine the stator current, power factor, developed power, shaft output power, speed, torque, and efficiency when the motor is running as a single-phase motor at rated voltage and frequency with its starting winding open.
Q. The machine of Problem can be used as a motor. Let the terminals of the coil be connected to a voltage source of 1 kV rms. If the motor runs at 1800 r/min and draws a current of
