Patent ID: 7770280

Claim:
A method for manufacturing multiphase windings of an electric machine with the following process steps: a) deforming a cross section of elongated wire elements by stamping a cross-sectional profile of said wire elements to increase a slot space factor; b) loading offsetting dies with some of the stamped wire elements to constitute a winding, with other of the stamped wire elements to constitute an integrated star point, and with further of the stamped wire elements for supplying current to the winding; c) forming a winding head with an integrated star point by simultaneously moving, by means of the offsetting dies, two legs of the some of the stamped wire elements, which are U-shaped, in a circumferential direction that is transverse to a longitudinal direction of the loaded stamped wire elements, arranging the other of the stamped wire elements, which have bent ends, so that their bent ends are orientated radially inwardly toward one another in a shape of a star, and arranging the further of the stamped wire elements on an outside of the winding head opposite to the other of the stamped wire elements; d) connecting the bent and radially inwardly oriented ends of the other of the stamped wire elements with a connecting ring, whereby an electrical contacting of the integrated star point is completed, and wherein the connecting ring is disposed radially inwardly on an inside of the winding head.
