4-22-A three-phase, 12-pole, 60-Hz-, 2200-V induction motor runs at no-load with rated voltage and frequeney impressed and draws a line current of 20 A and an input power of 14 kW , the stator is Y- connected, and its resistance per phase is 0.4 2. The rotor resistance ŕ2 is 0.2 2 per phase. Also, Xi+X'z= 2 Q the motor rune at a slip of 2% when it is delivering power to a load. For this condition compute: (a) The developed torque. (b) The input line current and power factor.
