Abstract: An electric machine includes a stator and a housing. The stator includes a laminated stator core and a first stator-side coupling element located at a height of an axis of the electric machine in an area of the laminated core. The first stator-side coupling element includes a first slot. The stator includes annular stator elements accommodating the first stator-side coupling element. The housing includes a first housing-side coupling element located at the height of the axis of the electric machine in an area of the laminated core and having a second slot. Screw connections provide a connection between the first stator-side coupling element and the first housing-side coupling element, and a key forms part of the connection between the first stator-side coupling element and the first housing-side coupling element. The stator is aligned in relation to the housing by at least two keys.

Abstract: An electric machine includes a housing for holding a cooling device, wherein the housing is provided for respectively holding a cooling device of different size, where the electric machine also includes an air cooling section that includes a first air guidance element for guiding the cooling air and includes a first positioning element for positioning the first air guidance element at a multiplicity of positions, where brackets are provided for positioning elements and the brackets can be oriented in an axial direction of the electric machine such that housings of similar size can be used for electric machines.
