eng	Experimental Research of Harmonic Spectrum of Currents at Traction Drive with PMSM	The paper deals with the significant results of the experimental research of the harmonic spectrum of currents and induced voltages at traction permanent magnet synchronous motor (PMSM). The experiments were done in a special workplace with a real traction drive for wheel vehicles. The current harmonic spectrums were analyzed by a specialized device on the basis of a central measuring station. The knowledge of marked subharmonic components of stator winding currents is the most significant finding of these experiments. 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 legislative requirements to electromagnetic compatibility (EMC) of drive with railway interlocking devices.
