A 400-V, 15-hp, 50-Hz, six-pole, A-connected induction motor has the following impedances in ohms per phase referred to the stator circuit: R1= 0.5 ohm XI=0.8 ohm R2=0.6 ohm X2= 1.2 ohm Xm = 60 ohm The total rotational losses are 0.5 kW. The core loss is lumped in with the rotational losses. For a rotor slip of 7 percent at the rated voltage and rated frequency: 1- Draw the motor three phase equivalent circuit. 2- Find the synchronous speed. 3- Find the motor speed
