Analysis of Bearing Current of the Inverter-fed Induction Motor Using Equivalent Circuit Parameters by FEM

摘要

This paper deals the analysis of bearing current in a 3-phase inverter-fed induction motor. We used numerical method (FEM) to derive parasitic impedances in our strategy. Then we compared the proposed method with conventional method in 60Hz no-load condition. From the comparison of simulation and experiment results, we confirmed that the proposed method is valid.
