Method for stator shorted turn fault detection using opposed pair-phase voltage/current of electric motor

摘要

The present invention facing in the structure of SPIMSM having a permanent magnet surface-mounted independent windings facing relates to an interlayer short circuit failure diagnosis method using the voltage / current on the watch, more than the three-phase even-numbered multi-phase of a polyphase synchronous motor with independent wiring structure comprising the steps of measuring the sum of the voltage / current on the viewing calculating the phase difference of the counter electromotive force waveform, and facing each other on, failure of the said measurement data two inputs (presence or absence of the steady state), the first output (voltage / current on the facing each other) back propagation neural network algorithm (back propagation neural network algorithm) by the learning of the steady state phase is facing using makin comprising the step of diagnosing failure of the SPIMSM. ;
