摘要

The race has a plurality of length sections and is operable to produce a travelling field adapted to move a movable body along said race so as to partly cover successive ones of said length sections in succession. The race also comprises a polyphase exciter winding having a plurality of polyphase winding sections, which are electrically disconnected from each other and arranged in respective ones of said length sections. Each of said polyphase winding sections consists of a plurality of phase windings. A plurality of capacitors are provided, each of which is connected in parallel to one of said phase windings and adapted to compensate a reactive current flowing in said phase winding. Non-contacting switching means are provided to apply an interlinked polyphase voltage to each of said polyphase winding sections when said body approaches the associated length section of said race and to remove said interlinked polyphase voltage from said winding section in response to the completion of the movement of said body along the associated length section. Said switching means comprise a plurality of thyristors which are connected to respective ones of at least all but one of said phase windings in each of said polyphase winding sections and adapted to be rendered conductive to apply said interlinked polyphase voltage to the associated polyphase winding section, and firing pulse generator means adapted to render each of said thyristors conducting only at a cross over of the interlinked polyphase voltage in the respective phase.
