A 400-V, 18-hp. 50-Hz, four-pole, A-connected induction motor has the following impedances in ohms per phase referred to the stator circuit: RI= 0.5 ohm XI=1 ohm R2-0.4 ohm X2= 1.2 ohm Xm = 80 ohm The total rotational losses are 1.5 kW. The core loss is lumped in with the rotational losses. For a rotor slip of 5 percent at the rated voltage and rated frequency: 1- Draw the motor three phase equivalent circuit. 2- Find the motor speed 3- Find the stator current 4- Find the line current 5- Find the stator power factor
