Abstract

The prediction of common-mode currents in inverter-driven induction motors is necessary to propose mitigating solutions in order to prevent failures and ensure the proper operation of the entire electrical system. The motor model for these high-frequency studies is relatively simple; however, to find its parameters accurately is a very complex task. In this context, this paper presents an alternative to estimate leakage capacitances in induction motors, based on the finite element technique, through computational simulation using FEMM (Finite Element Methods Magnetics). Then, an application of the motor capacitances in an appropriate model for common-mode quantities determination is shown as an example, using the ATP (Alternative Transients Program).
