1. An electric motor comprising:
a housing including an inner surface and an outer surface positioned radially outward from the inner surface;
a stator coupled to the inner surface;
and
a cooling channel positioned within the housing between the inner surface and the outer surface; wherein the cooling channel includes:
a radially inward cooling surface,
a radially outward cooling surface parallel to the radially inward cooling surface,
a first side surface extending from the radially inward cooling surface, and
a second side surface extending from the radially outward cooling surface;
wherein the first side surface is non-orthogonal to the radially inward cooling surface, wherein the second side surface is non-orthogonal to the radially outward cooling surface, and wherein the first side surface and the second side surface intersect at a point;
wherein the housing is additively manufactured with the cooling channel formed therein.
