Problem 2 (Induction Motor) A three phase, Y connected, 220 V, 60 Hz, 6 pole induction motor has the following constants for its equivalent circuit (use circuit in slide 22): R1 0. 29 Ω X-0. 5 Ω Xm 13. 25 Ω R2-: 0. 14 Ω (referred to stator side) X2-021 Ω (referred to stator side) Ignore Rc. When the motor is operated at rated voltage and rated frequency, the slip rate is 0. 2. The total friction and windage losses are 403 W, ignore the core loss. Calculate: a) Rotor speed (rpm) b) Stator current and power factor c) Load power and torque
