Abstract

The paper deals with the research results of the harmonic spectrum of currents and induced voltages at traction drive. A permanent magnet synchronous motor is used at this drive. The harmonic spectrums of currents were analysed by a specialized device. The knowledge of subharmonic components of stator winding currents is the most significant finding of these researches. The frequencies of these components are given by frequency multiples of mechanical speeds. The subharmonic components also pass to the DC current at an input site of the traction inverter. This fact is particularly important from the viewpoint of the legislative requirements to electromagnetic compatibility of drive with railway interlocking devices
