Abstract
An electric motor can include a stator body defining fluid channels extending axially for fluid communication between axial ends of the stator body. Conductive windings can form first loops extending axially outward from the first end of the stator body and second loops extending axially outward from the second end of the stator body. A first cap can be coupled to the first end of the stator body and can include a first wall. The first wall can be between the first loops and the channels. Pins can extend from a side of the first wall that is opposite the first loops. The second cap can be coupled to the second end of the stator body and include a second wall. The second wall can be between the second loops and the channels. Pins can extend from a side of the second wall that is opposite the second loops.
