System for an electric motor with coil assemblies and internal radial magnetic elements

A system for an electric motor comprising:

• a rotor comprising a set of magnetic elements arranged radially about a motor axis within a 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 stator comprising a set of coil assemblies arranged in a radial pattern about the rotor, each coil assembly in the set of coil assemblies comprising:
• an outer hook element extending across the first axial face and the outer radial surface of the rotor, and comprising a first set of leads;
• and
• an inner hook element:
• extending across the second axial face of the rotor;
• extending partially across the inner radial surface of the rotor;
• arranged normal to the outer hook element to define a throat configured to locate the rotor within the coil assembly;
• and
• comprising a second set of leads;
• a shaft coupled to the inner radial surface of the rotor and aligned to the motor axis;
• and
• a controller configured to drive current through the set of coil assemblies to generate a toroidal magnetic field configured to envelop the rotor and couple the set of magnetic elements of the rotor thereby rotating the rotor while embedded within the set of coil assemblies.
