Abstract: A housing for an electrical machine includes an endshield and a cover. The electrical machine has a rotation axis, a rotor assembly including a rotor, and a controller assembly. The rotor assembly includes a bearing assembly. The endshield includes an annular center section including a bore sized to couple to the bearing assembly. The cover is coupled to the endshield. The cover includes a generally axially-extending flange wall formed about a perimeter of the cover, a volute-shaped inner chamber configured to at least partially enclose the rotor coupled to the rotor assembly of the electrical machine, and a cooling channel positioned radially outward from the inner chamber. The cooling channel is configured to at least partially enclose the controller assembly of the electrical machine.
