摘要： 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.

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.

摘要： Methods and apparatus are provided for stator assembly for use with an electric motor assembly. The stator assembly includes, but is not limited to a stator core that has an inner surface and a plurality of stator slots defined in the inner surface. A fractional slot winding having a plurality of conductors is coupled to the stator core. Each stator slot contains a group of the conductors arranged in a radially adjacent configuration. The groups of conductors in each of the stator slots together form a plurality of concentric rings of conductors. The conductors in each mixed group are arranged such that conductors carrying differing phases of electric current are arranged in a radially alternating configuration.
