US 6,958,560 B2 · Winding arrangement for an electric machine

Abstract

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 (50, 52, 54, 56) are connected with a conductor rail (40, 42, 44, 46). This makes it possible to connect the coil ends directly and without connecting pieces with the electric power supply. The conductor rails (40, 42, 44, 46) 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 (50, 52, 54, 56) of the winding are connected with one of the conductor rails (40, 42, 44, 46).

Dependent claims

A winding arrangement for a stator of an electric machine with a polyphase winding having a plurality of phase branches, comprising:

coils or coil groups, and
conductor rails with at least one terminal,
in which each phase branch comprises a plurality of coils or coil groups connected in parallel;
in which the conductor rails are located at least partially around the stator;
and
in which at least one end of the coils or coil groups connected in parallel is connected with one of the conductor rails in such a way that said conductor rail forms a current conductor connecting the terminal with the parallel-connected coils or coil groups of a phase branch.
