Title:
VALVE ELECTRIC DRIVE
Document Type and Number:
WIPO Patent Application WO/2005/107048
Kind Code:
A1
Abstract:
The invention relates to electrical engineering, in particular to valve electric drives fed by a DC-voltage source. The inventive valve electric drive comprises an electric motor whose stator is provided with a closed-coil distribution winding disposed in the grooves thereof, a rotor and a switch based on controllable key elements which are connected according to a multiphase bridge net and are provided with the key element inputs for connecting to the DC-voltage source and with the key element outputs connected to the winding sections in such a way that a rotating magnetic field is formed. The novelty of the invention lies in that the switch is embodied in such a way that the outputs of the key elements thereof are connected to the connection points of the adjacent winding sections in such a way that the certain switch key elements sequentially connect the certain connection points of the adjacent winding sections to one of the DC-voltage source pole and the other key elements of the switch connect the other connection points of the adjacent winding sections, shifted at 180 electric degrees with respect to the first sections, to the other DC-voltage source pole.
