Abstract
A drive unit includes a stator assembly with a stator assembly core having a plurality of teeth that extend from a first end to a second end of the stator assembly core. The teeth have first, second, and third axial extents. The radially inboardmost portions of the first and second axial extents are radially inboard of the radially inboardmost portions of the third axial extent. The drive unit also includes a rotor assembly with first and second rotor bodies, a rotor mid plate, first and second rotor end plates, and a rotor shaft. The rotor assembly defines a portion of a fluid flow path of the drive unit including an interior hollow defined by the rotor shaft and a fluid passage defined by the rotor mid plate. Fluid is conveyed along the portion of the fluid flow path from the interior hollow to the fluid passage to the third axial extent.
