Abstract:

An electrical machine includes a stator and a rotor disposed in a housing of the electrical machine. The stator includes windings having a first set of end turns at a first end of the stator and having a second set of end turns at a second, opposing end of the stator. The stator has a substantially tubular shape and an interior lateral surface. The rotor extends through the interior of the stator. A flow inlet into a volume in the housing about the first end turns is located radially outside of the interior lateral surface of the stator. A flow outlet from the volume in the housing about the first end turns is located radially outside of the interior lateral surface. The inlet and the outlet are cooperatively arranged to communicate a flow of fluid substantially transverse across the first end of the stator.
