    Abstract: A permanent magnetic machine includes a stator body having a first end, a second end, and a plurality of generally radial slots formed therein for accepting a set of windings having a first set of end-turns at the first end and a second set of end-turns at the second end. The stator body has a plurality of channels adjacent to the slots and extending from the first end of the stator body to the second end of the stator body, wherein the channels are configured to allow the flow of a cooling fluid therethrough. A plurality of nozzles in fluid communication with the plurality of channels are configured to spray the cooling fluid onto the first and second set of end turns.

    Abstract: An electric motor assembly includes a motor shaft rotatable about a longitudinal axis, an angular position sensor, and a deformable pin. The motor shaft has an axial keyway formed therein, and the axial keyway has a nominal keyway dimension. The angular position is coupled to the motor shaft to rotate with the motor shaft. The angular position sensor has an axial key to fit within the axial keyway of the motor shaft, and the axial key has a nominal key dimension that is less than the nominal keyway dimension. The deformable pin is located in the axial keyway under compression between the axial key and the motor shaft to inhibit rotational shifting of the angular position sensor relative to the motor shaft.
