1. A system for an electric motor comprising:
a set of magnetic elements arranged radially about a motor axis within a body, the body defining:
an inner radial surface;
an outer radial surface;
a first axial face; and
a second axial face opposite the first axial face;
a set of coil assemblies arranged in a radial pattern about the body, a first coil assembly in the set of coil assemblies comprising:
a first coil winding extending across the first axial face and the outer radial surface of the body; and
a second coil winding:
extending across the second axial face of the body; and
arranged orthogonal to the first coil winding to define a throat configured to locate the body within the coil assembly; and
a shaft coupled to the body and coaxial with the motor axis.
