Abstract: Disclosed are various embodiments for a linear machine having a magnetic torque tunnel stator comprising an outer core assembly formed of a plurality of exterior permanent magnets couple to the inside retaining wall of a tube, where adjacent exterior permanent magnets are separated by an exterior ring spacer of ferromagnetic material, and an interior core assembly having a plurality of interior permanent magnets coupled to the outside wall of a central core, where adjacent interior permanent magnets are separated by an interior ring spacer of ferromagnetic material, the magnetic poles of the exterior and interior permanent magnets configured to face each other, and a coil winding assembly armature configured to be slidably positioned within the magnetic torque tunnel of the stator.

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.
