Abstract

An end plate for a rotor assembly of an electrical machine includes a central through-opening for a shaft, a collar formed on an end face of the end plate on the radial outside in the circumferential direction and a plurality of elevations on the end face. The elevations and collar axially delimit a cooling channel, wherein the cooling channel forms a plurality of cooling channel sections on both sides by a respective elevation. Two elevations delimiting a cooling channel section are spaced apart from one another by a first arc length at a first radial position between the through-opening and the collar and are spaced apart from one another by a second arc length greater than the first arc length at a second radial position delimited by the collar. Each cooling channel section includes at least one fluid guide element between the first radial position and the second radial position.
