Abstract:
1. An electrical machine comprising: a stator disposed in a housing of the electrical machine and comprising windings having a first plurality of end turns at a first end of the stator and a second plurality of end turns at a second, opposing end of the stator, the stator having a substantially tubular shape and an interior lateral surface; a rotor extending through an interior of the stator; a partition defining a volume in the housing about the first end turns; a flow inlet into the volume about the first end turns, the flow inlet located radially outside of the interior lateral surface; and a flow outlet from the volume about the first end turns, the flow outlet comprising a port through the partition located radially outside of the interior lateral surface, the inlet and the outlet cooperatively arranged to communicate a flow of fluid from a first point on a radial exterior of the first end turns substantially transverse across the first end of the stator to the flow outlet.
