Abstract：High voltage square impulses from converter can make stator insulation of inverter-fed motors damaged much earlier. There are many differences in insulation aging mechanism between under continuous impulses and under sine voltages. In order to test insulation properties under continuous impulses, a new insulation aging test system is used to simulate the aging effect of converter on the winding insulation in the inverter-fed motors. The influences of impulse amplitude and frequency on insulation lifetime are investigated by using polyimide film. Finally, an insulation electrical aging lifetime model is proposed.
