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.
