Electric motor and stator cooling apparatus

An electric motor comprising:

• a housing;
• a stator body disposed about an axis, the stator body defining a plurality of fluid channels that extend axially through the stator body to provide fluid communication between a first axial end of the stator body and a second axial end of the stator body;
• a rotor disposed about the axis and rotatable relative to the stator body;
• a plurality of electrically conductive windings forming a plurality of first winding loops extending axially outward from the first axial end of the stator body and a plurality of second winding loops extending axially outward from the second axial end of the stator body;
• a first end cap coupled to the first axial end of the stator body, the first end cap including a first wall and a plurality of first pins, the first end cap and the housing defining a first fluid cavity in fluid communication with the fluid channels, the first end cap defining a first winding cavity separated from the first fluid cavity by the first wall, the first winding loops being disposed within the first winding cavity, the first pins extending from the first wall into the first fluid cavity;
• and
• a second end cap coupled to the second axial end of the stator body, the second end cap including a second wall and a plurality of second pins, the second end cap and the housing defining a second fluid cavity in fluid communication with the fluid channels, the second end cap defining a second winding cavity separated from the second fluid cavity by the second wall, the second winding loops being disposed within the second winding cavity, the second pins extending from the second wall into the second fluid cavity.
