Abstract: One variation of a system for an electric motor includes a set of coil assemblies defining: an inner radial facet, an outer radial facet, a first axial facet, and a second axial facet opposite the first axial facet. Additionally, each coil assembly in the set of coil assemblies includes a receiving member arranged at the outer radial facet of the coil assembly. Furthermore, the system includes a rotor comprising a set of magnetic elements: encompassing the inner radial facet, the outer radial facet, the first axial facet, and the second axial facet of the set of coil assemblies; and defining a radial magnetic tunnel. The system also includes a housing: engaging the receiving member of each coil assembly, in the set of coil assemblies to couple the housing to the set of coil assemblies; and includes a shaft coupled to the set of magnetic elements.

Abstract: 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.
