ABSTRACT:
A synchronous linear motor having an exciter disposed as a co-moving translator on a track bound vehicle, and having a traveling field winding comprising switching sections which are supplied from a stationary, controlled static frequency changer, wherein the traveling field winding is subdivided into a plurality of individual conductors disposed and connected electrically in parallel so as to reduce the operating reactance. The harmonic content is reduced by an asymmetrical spacing of the individual conductors.
