A 1/3 hp, 110-V, 60-Hz, six-pole, split-phase induction motor has the following impedances: R1 = 1.52 , R2 = 3.13 , X1 = 2.10 , X2 = 1.560, XM = 58.2 The core losses of this motor are 35 W, and the friction, windage, and stray losses are 16 W. The motor is operating at the rated voltage and frequency with its starting winding open, and the motor's slip is 5 percent. Find the following quantities in the motor at these conditions: (a) Motor speed (c) Stator power factor (e) Pag (g) Ta (i) Tload (b) Stator current and power factor (d) Pin (f) Pconv (h) Pout (j) Efficiency
