Abstract
Voltage distribution in windings is important for inverter-fed traction motors. The analysis on voltage distribution characteristics is significant to the study of insulation failure mechanisms and structure design. First, a distribution parameter model has been developed according to the winding structure of an inverter-fed traction motor. Based on the model, finite element differential method was employed to determine voltage distribution characteristics. Simulation results were compared with actual voltage distribution. Moreover, the influence of pulse rise time and cable was discussed. The results show that the shorter the pulse rise time is, the more uneven the voltage distribution is. In addition, cable length has little influence on voltage distribution characteristics. However, the amplitude of voltage would also increase by 40% in coils and turns.
