Speech Title: Advantages of permanent magnet synchronous traction motors for high-speed EMUs and challenges of intelligent operation and maintenance

Abstract: High-power permanent magnet synchronous motor (PMSM) as the next generation of green energy-saving high-speed EMU traction motor, if it is not designed or operated properly, there will be serious potential demagnetization lead to damage IGBT. To tackle the big challenges of unclear faulty mechanism, difficult acquisition of direct loss-of-excitation signals, serious attenuation of related indirect electric signals and vibration signals under high-speed and heavy-load operation conditions, low signal-to-noise ratio and easy missed diagnosis of permanent magnet synchronous traction motor of high-speed EMU, this topic includes using multi-type sensor information fusion and artificial intelligent technologies to conduct online healthy monitoring and to reveal faulty mechanism of high-speed EMU traction.
