Patent ID: 7154201

Claim:
An electrical machine, comprising: a rotor; a stator having an end winding; and at least one bearing, wherein the rotor is effectively connected with a rotor shaft rotationally mounted in a housing by means of the at least one bearing, wherein the bearing is located in a bearing end plate, wherein a seal shield or a cover shield forms an enclosed coolant space that extends from the bearing end plate at least partly into the vicinity of the stator end winding, wherein the seal shield or the cover shield is provided with a widened portion that extends to the stator end winding and forms an enclosed coolant annulus that is located in the vicinity of the stator end winding, with the stator end winding at least partly overlapping an inside periphery of the coolant annulus, wherein the bearing end plate includes at least one coolant space that transports a coolant flow, and wherein liquid coolant flows through the enclosed coolant annulus and does not directly contact the stator end winding.
