Abstract :
A new fault detection method for induction machines (IM) is analyzed with respect to transient magnetic material behavior by means of finite element (FE) modeling. The detection method uses the machines inverter to excite the IM with transient voltage pulses and measures the corresponding phase current responses. To account for the material behavior transient BH curves are identified from measurements on a demagnetized magnetic circuit and included in the FE model to accurately simulate pulsed voltage excitations.
