Abstract :
In this paper, several inverter-fed induction machines with rated powers between 1.5 and 240 kW are modeled for calculating the common mode (CM) stator ground current and the capacitive bearing voltage. Simple methods to extract the parameters of the high-frequency machine model from the measured CM and differential mode impedances are presented. Furthermore, the most significant parameters are given for five different machine sizes between 1.5 and 240 kW rated power. Calculation examples are provided in comparison to the experimental results.
