1. By making use of power flow diagrams, outline the efficiency of induction motors and generators. 2. A 10Hp. 4 pole, 25 Hz, 3-phase, wound rotor induction motor is taking 9100 watts from the line. Core loss is 290-watt, stator copper loss is 568-watt, rotor copper loss in 445-watt, friction and windage losses are 100 watts. Determine; (a) power transferred across air gap; (b) mechanical power in watt developed by rotor; (c) mechanical power output in watt; (d) efficiency;
