A connecting system for a stator assembly () and a plug housing () can be inserted into an opening in a stator housing (). A plug housing receptacle () is provided in the stator assembly (). The plug housing () engages the housing receptacle such that it is movable relative to the stator assembly () in at least two perpendicular directions when mounted.

Connecting system for plug positioning

A diffuser () for a fan () of axial, radial or diagonal type of construction, has an inlet opening () and having an outlet opening () for a gaseous medium which flows through a diffuser interior (I), which is enclosed by an outer housing (), in an axially oriented main flow direction (S) from the inlet opening () to the outlet opening (). The cross section of the diffuser interior (I) increases from the cross section () of the inlet opening to the cross section () of the outlet opening (), wherein the outer housing () forms an outer diffuser part (AD) which delimits the diffuser interior (I) to the outside. Along the main flow direction (S), the cross section of the outer diffuser part (AD) changes from a circular cross section () at the inlet opening () to a non-circular cross section () at the outlet opening ().

Fan diffuser having a circular inlet and a rotationally asymmetrical outlet

A rotating electric machine () having a stator () in a housing () and a rotor () supported by a shaft (). The housing () circumferential wall () and first and second axially opposing end walls () support bearing flanges with bearings () for the shaft (). Two cooling fan impellers () are connected to the shaft (). An inner cooling fan impeller () positioned inside the housing () generates an inner cooling air circuit (A) inside the housing (). An outer cooling fan impeller () provided outside the housing (), generates an outer cooling air flow (B). The first end wall () is formed with a thermal conductivity of at least a specified value and has an outer cooling rib geometry () on its outer side facing the outer cooling fan impeller (), and an inner cooling rib geometry () on its opposing inner side.
