| Abstract: | Stator insulation of inverter-fed motors is experiencing continuous impulses with significant harmonics and transients. There are many differences in insulation aging mechanism between under continuous impulses and under sine waves. However, there are few papers which discuss the life curve under continuous impulses. In order to test insulation properties under continuous impulses, a new insulation aging test system is developed. The influences of impulse amplitude, frequency, temperature on insulation life are investigated by using polyimide film. Finally, a novel insulation life model is developed based on the above test results. It is helpful for the insulation design of inverter-fed motor. |
