Abstract: The invention relates to an electric motor comprising an electronics housing having motor electronics accommodated therein and a stator housing arranged axially at a distance from the electronics housing, wherein, axially between the electronics housing and the stator housing there is arranged a twin-flow cooling wheel which, during operation, generates a first cooling air stream along the electronics housing and a second cooling air stream along the stator housing and/or at least one bearing shield adjoining the stator housing axially.

Abstract: The method of making an electromagnetically excitable core of an electrical machine with a multiphase winding (13) includes preparing a core (10) having a substantially parallelepiped shape, which is provided with a plurality of parallel grooves (N1 to N36; N1 to N48) in one side in a first step. In at least one subsequent step at least three phase windings (100, 200, 300) are laid in these grooves in such a manner that only one winding overhang is outside of the core.

Abstract: A winding machine (20) has a carrier device (23) for winding a winding for an electrical machine. The carrier device (23) has at least one group (34) having a winding template (29) and an adjacent deflection element (31), and the winding template (29) and the adjacent deflection element (31) are displaceable relative to one another. In a method for producing a winding from at least one coil, at least one wire is wound around a winding template (29), producing at least one wire arrangement with at least one first coil side (68), at least one first deflection side (69), and at least one second coil (70), and a winding template (29) is displaced out of a plane for the winding process.
