    摘要: 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.

    摘要: An internal permanent magnet machine (“IPM machine”) of the type used, for example, with traction motors and hybrid electric vehicles, includes a rotor having a plurality of equal-sized (e.g., rectilinear) segmented ferrite magnets arranged in one or more layers. The magnets are inserted within rotor slots that are larger than the magnets themselves, such that one or more air gaps are formed adjacent to the magnets in each layer.

    摘要: An electric motor assembly includes a motor shaft rotatable about a longitudinal axis, an angular position sensor rotor, 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 sensor rotor is coupled to the motor shaft to rotate with the motor shaft. The angular position sensor rotor 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 rotor relative to the motor shaft.

    摘要: Damping mechanisms and motor assemblies are provided. In an embodiment, by way of example only, a damping mechanism includes an end cap, a bearing retainer plate, a bearing damper ring, a bearing assembly, and first and second lateral dampers. The bearing damper ring is disposed in an annular cavity inwardly from an inner diameter surface of the end cap and has a radially inwardly-extending flange. The bearing assembly is disposed in the annular cavity radially inwardly relative to the bearing damper ring. The first lateral damper is disposed between a radially inwardly-extending wall of the end cap and the bearing damper ring. The second lateral damper is disposed between the bearing damper ring and the bearing retainer plate.
