Japanese Patent JP7304786

Kind Code:

B2

Abstract:

The present invention addresses the problem of providing a rotating machine drive system comprising a winding switching device, wherein the rotating machine drive system has a relatively simple configuration, allows wear of electrical contacts during switching and sliding to be minimized, and is highly reliable. The present invention is characterized in comprising a rotating machine having a plurality of windings, an inverter device for operating the rotating machine at variable speed, and a winding switching device for switching connection of the plurality of windings; the winding switching device having winding terminals, a semi-moving element having a short-circuit part that faces the winding terminals and also having a sliding part provided with first protrusions on the surface thereof opposite from the surface having the short-circuit part, and a moving element facing the sliding part of the semi-moving element and having a sliding part provided with second protrusions on the surface facing the sliding part of the semi-moving element; the moving element being made to slide relative to the semi-moving element, whereby the connection between the winding terminals and the short-circuit part is changed and the connection of the plurality of windings is switched.
