Drive switching device for magnetic train track has drive regions divided into at least 3 supply regions, region not bounding on inverter electrically switched to one or other of pair of inverters

摘要

The magnetic train track has a synchronous stator drive, whereby a roadway (1) is divide into electrically isolated drive regions (A) via pairs of inverters (Un,Un+1,..). The drive regions are divided into at least three supply regions (S1-S3), whereby the supply region that is not bounding on an inverter can be electrically connected to one or other inverter of the pair of inverters via a switching device (6).
