3 Phase 50 Hz 25 Hp asynchronous motor 415 V triangle is working. It rotates at 1480 rpm/mın under full load. Stator phase effective resistance Rs=0.02 ohm stator phase leakage reactance Xs=0.25 ohm According to the stator terms, the effective phase resistance of the rotor is R2=0.06 ohm and the leakage phase reactance of the rotor is X2=0.2. The motor draws 750 W at idle. a- Calculate the current that the motor will draw as it will start directly in the first developmentb- Calculate the initial moment of development,c- Since the motor is running under full load, draw the equivalent circuit and draw the current drawn by the motor from the mains,
