Abstract :
The paper mainly researched how the Wye and delta connection affect the copper losses in induction motor under over-voltage condition. The multi-slice time-stepping finite element method (FEM) was utilized to calculate the copper losses of a 5.5-kW skewed motor under no-load and different load conditions respectively. It is shown that, when the motor is supplied with 10% over-voltage, the delta connection can increase the copper losses by approximately 15 percent under no-load condition. Furthermore, with the load increasing, the disparity of the total copper losses of the two different connections is becoming smaller.
