ECE 320: Energy Conversion and Power Electronics Name: Spring 2009 Homework #5 (Due: Monday, April 6, 2009) Circle or box your answer (don’t forget units). Staple any additional paper used to arrive at your answers to this sheet. 1. A 3-phase 2-pole induction motor is rated 230 (V), 60 (Hz) with Y-connected windings. The stator and rotor resistances are 1 and 2 ( ), magnetizing reactance is 100 ( ), stator and rotor side leakage reactances are 2 and 2 ( ), respectively. a. Calculate the starting torque. b. Calculate the no-load current and power factor.
