Abstract: An electric machine, characterized by two partial machines, each of which has a housing with a bottom-side end wall, in which in each case a stator and a rotor having a hollow rotor arm is accommodated, the two housings being arranged adjacent to one another with their bottom side end walls, with a common distribution device being provided in a cavity between the two housings for distributing a coolant that is used to cool the rotors and which is coupled with at least one housing-side inlet via which the coolant is supplied, and at least one housing-side outlet via which the coolant is discharged, and which is formed to distribute the coolant supplied into both hollow rotor arms and to guide the coolant flowing back from it to the at least one outlet.

Abstract: An electric machine comprising at least one housing in which a rotor having coolant guide vanes provided at an end face is accommodated, and an annular cooling fin structure through which coolant conveyed by the coolant guide vanes is passed and having cooling fins which are axially covered by an annular cover section in such a way that there is an inlet area for the coolant supplied by the coolant guide vanes and an outlet area, wherein the cooling fin structure is formed on a side of an axial end wall of the housing facing the interior of the housing, on which an annular disk-shaped cover forming the cover section is attached.

Abstract: A coolant distributor for a machine configuration. At least one coolant forward flow inlet opening and at least one coolant return flow outlet opening as well as multiple coolant forward flow outlet openings and multiple coolant return flow inlet openings are formed in a distributor body of the coolant distributor. The coolant forward flow inlet opening is fluidically connected by way of a forward flow chamber present in the distributor body to the coolant flow outlet openings, and the coolant return flow inlet openings are fluidically connected by way of a return flow chamber to the coolant return flow outlet opening and the coolant forward flow inlet opening is separated fluidically within the distributor body from the coolant return flow outlet opening, and wherein the distributor body is composed of two identical parts, which between them form the forward flow chamber and the return flow chamber.
