Abstract

The invention relates to an active part (18) of an electric machine (10), comprising a number of coils (20), each having a partial conductor (24). The coils (20) are formed by windings of the partial conductors (24) thereof, wherein the windings of a coil (20) each have a predetermined winding length. In addition, the active part (18) has a carrier part (22), in the grooves of which the coils (20) are arranged. The coils (20) have a winding head region that projects from an end surface of the carrier part (22). The coils (20) are also arranged in the form of a tiered winding. The object of the invention is to form an active part of an electric machine and in particular the winding head region thereof in a particularly compact manner. For this purpose, at least one of the coils (20) has a V-shaped cross-section in the winding head region, as a result of an arrangement of its partial conductor (24).

Description

Technical field [0001] The invention relates to an active part of an electrical machine. Here, the active part has a plurality of coils and a carrier part, the coils have a sub-conductor each, and the coils are arranged in slots of the carrier part. The coil is formed by windings of its sub-conductors, wherein the windings of the coil each have a predetermined winding length. In addition, the active part has at least one winding head region, which projects on the end face of the carrier part. In addition, the coils are arranged in the form of layered windings. In addition, the present invention includes an electrical machine having an active part according to the present invention and a method for manufacturing the active part. Background technique [0002] Electrical machines, such as engines, generators, and transformers each have one or more active parts that are magnetically active. The engine has a stator and a rotor as corresponding active parts, for example. [0003] Th...
