Abstract
An electric machine with fluid cooling. The electric machine includes a stator, the stator having a stator winding and a stator core having a plurality of stacked magnetic laminations, each of the laminations of the stator core having a plurality of apertures overlapping to form a plurality of stator fluid channels, a stator fluid channel of the plurality of stator fluid channels being not entirely axial. The electric machine further includes a rotor, the rotor having a shaft and a rotor core having a plurality of stacked magnetic laminations, each of the laminations of the rotor core having a plurality of apertures overlapping to form a plurality of rotor fluid channels, and a rotary fluid coupling in fluid communication with the rotor fluid channels. The rotor and the stator are configured to form a magnetic circuit comprising an air gap between the rotor and the stator.
