The invention relates to a winding arrangement for an electric machine with a polyphase winding, in which a plurality of coils or coil groups connected in parallel () are connected with a conductor rail (). This makes it possible to connect the coil ends directly and without connecting pieces with the electric power supply. The conductor rails () are preferably arranged at one or both face sides of the post of the electric machine below the slot openings, i.e., in the area of the back of the post. Furthermore, the invention is aimed at an corresponding manufacturing method for a winding arrangement of a polyphase winding for an electric machine, in which the coils or coil groups connected in parallel () of the winding are connected with one of the conductor rails ().

Winding arrangement for an electric machine

The invention concerns a winding for a post or an armature of an electric machine with a post or armature () with slots () composed at least in part of L-shaped structural parts (). In doing so, one leg of an L-shaped structural part each time creates a slot bar () located in a slot, and the other leg creates a connecting line () located at a face of the post or armature. Moreover, the invention concerns a winding with several interlaced coils (&#x2033;) whereby the connecting lines () of interlaced coils (&#x2033;) are staggered and therefore arranged in layers. The invention furthermore concerns a winding with connecting lines () flatter than the slot bars (), styled as a fractional pitched polyphase winding with two slots per pole and branch. The invention also covers a winding consisting of several coils (&#x2033;), characterized by the fact that at least two coils () are connected in series, whereby the current flows through one coil () in the direction of the slot head, and in the other coil () in the direction of the slot bottom. The invention also concerns a procedure and a set of structural parts to manufacture a winding for an electric machine.
