A 0.5-HP 220-volt 60-Hz 6-pole split-phase induction motor has the following impedances referred to the stator: R1 = 3 ohm X1 = 6 ohms R2 = 8 ohms X2 = 4 ohms The mechanical and core losses of this motor are 25 watts. The machine is operated at rated voltage and frequency with its starting winding already open. For this problem, use 1-HP = 746 watts. Xm= 100 ohms Determine the rotor speed (equivalent to determining the slip) at which the output of the motor will be equal to its rated value of 0.5 HP = 373 watts. Give your answer in RPM with 0 decimal places. Answer:
