Presented is a winding arrangement for an electric machine that includes a laminated core that includes a yoke that includes a plurality of teeth each having flanks that form first wedge surfaces and a winding support area that has a trapezoidal cross-section. The arrangement further includes a coil winding, and a winding body configured to arrange the coil winding on one of the plurality of teeth. The coil winding has an inner area arranged opposite the first wedge surfaces and represents second wedge surfaces. The arrangement further includes a stop means disposed on the winding body and/or one of the plurality of teeth. The stop means is configured to limit movement of the winding body in a direction toward the yoke. The arrangement further includes a centering means configured to center the winding body on one of the plurality of teeth.

Winding arrangement for an electrical machine

A winding body for holding a winding of an electrical conductor to produce a coil for an electrical machine includes a winding area formed by a winding support and two sidepieces connected to the winding support. The sidepieces form the boundaries of the winding area and are connected to the winding support. Various measures are proposed for mounting a compact winding on the winding body, for arranging the winding body without play and in an operationally reliable manner on a tooth of an electrical machine, and for wiring several coils together in a space-saving manner by using the winding body.

Winding body for a coil of an electrical machine

A stator for an electrical machine includes a ring-shaped stator yoke with a number of stator coils arranged thereon. The conductor ends of the coils are designed to be connected to a wiring arrangement, where the wiring arrangement has linking conductors, which are arranged concentrically to each other, are insulated electrically against each other, and have terminal elements to form electrical contact areas by which they are connected to the ends of the stator coils. The ends of the coils be connected to the linking conductors by separate terminal elements which have a first contact area for establishing a connection with the linking conductor and a second contact area for establishing a connection with at least one coil end.
