Abstract
The present disclosure relates to electric motors having fluid cooling by fluid flow through a cooling jacket cavity. An electric motor may include a cylindrical housing wall, a stator mounted to an inner surface of the housing wall, a motor shaft mounted for rotation within the housing wall, and a cooling jacket wall surrounding and concentric with the housing wall. A housing wall outer surface and a jacket wall inner surface define the cooling jacket cavity, and the cooling jacket wall has a fluid inlet port and a fluid outlet port. Cooling fluid flows into the cooling jacket cavity through the fluid inlet, flows through the cooling jacket cavity over the housing wall outer surface, and flows out of the cooling jacket cavity through the fluid outlet.
