Abstract
One variation of a system for an electric motor includes a rotor including magnetic elements within a body. The system also includes a stator including coil assemblies arranged about the rotor. Each coil assembly includes an outer hook element and an inner hook element. The outer hook element extends across a first axial face and an outer radial surface of the rotor. The inner hook element: extends across a second axial face of the rotor; extends partially across the inner radial surface of the rotor; and is coupled to the outer hook element to define a throat configured to locate the rotor within the coil assembly. The system includes a shaft coupled to the inner radial surface of the rotor. Furthermore, the system includes a controller configured to drive current through the coil assemblies to generate a toroidal magnetic field configured to couple the magnetic elements to rotate the rotor.
