Abstract :
The prediction of transient overvoltage and 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 techniques, using FEMM (Finite Element Methods Magnetics). Then, an example of the motor capacitances in an appropriate model for common-mode quantities determination is shown, using the software ATP (Alternative Transients Program).
