Patent attributes
An electric motor includes a case, a stator that includes a stator laminaiton and end-windings, a rotor coupled to the case via at least one rotor bearing. The rotor includes a hollow cylindrical body, a first shaft portion, and a second shaft portion. The hollow cylindrical body includes an inner wall, an outer wall, a first distal end, and a second distal end. The first shaft portions couples to the first distal end and the second shaft portion couples to the second distal end. The second shaft portion includes a fluid feed tube formed therewith having a fluid receive end and a fluid feed end, the fluid feed end extending to a central inner portion of the hollow cylindrical body. A plurality of fluid exit ports adjacent the first distal end and the second distal end of the hollow cylindrical body spray fluid onto components of the stator.
