20 Marks A 500 V 50 hp 80 Hz four-polo y connected induction motor has the following impedances in ohms per phase referred to the stator circuit RI=0.9 ohm XI - 11 ohm RI=04 cm XI 05 ohm XM = 25 ohm The total rotational losses aro 1100 W and are assumed to be constant. The core loss is lumped in with the rotational losses For a rotorship of 2 percent of the ruled voltage and rated frequency find the motor's (a) Speed (D) Stator current (c) Power factor (a) Poony and Pout ( ond and Toad (0) Ency BT- HT = #
