    Abstract: A dual-rotor machine comprising a dual rotor support structure rotatably connected to a frame. A stationary stator is disposed between the rotors and is fixed to the frame. An inner rotor and outer rotor, each comprising a permanent magnet Halbach array, are coaxially disposed with the stator and are rotable about the stator. In this configuration, the inner rotor channels its magnetic flux to its outside, while the outer rotor channels its magnetic flux to its inside. The magnetic flux density at the stator for the dual-rotor machine can be as high as 2 Tesla or higher for high-grade neodymium-iron-boron permanent magnet material, and the stored magnetic energy for conversion to mechanical or electrical energy available to the stator may be at least 0.5 kJ/m. The rotor Halbach arrays may comprise monolithic permanent magnets with continuously variable magnetic field direction.

    Abstract: The present invention provides a method of manufacturing magnets, including magnets comprising coil windings which may be multiple meters in length. In an embodiment, the support structure comprises a cylinder in which machined grooves are formed to define the magnet conductor path. The segments may consist of a composite material or a metal in the shape of a cylinder, but which need not be manufactured from a single piece of material. Rather, the support structure may be formed in multiple connectable segments which, when connected together, form a completed wiring support structure. Each segment may be of sufficient length to support multiple individual coil turns in a helical configuration. When the segments are connected the helical configuration continues without interruption from connectable segment to connectable segment. The segmented wiring support structure of the invention may be applied to linear or curved magnet geometries.

    Abstract: A conductor assembly and method for making an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one series of embodiments the assembly comprises a spiral configuration, positioned along paths in a series of concentric cylindrical planes, with a continuous series of connected turns, each turn including a first arc, a second arc and first and second straight segments connected to one another by the first arc. Each of the first and second straight segments in a turn is spaced apart from an adjacent straight segment in an adjoining turn.

    Abstract: Systems and methods for removing plaque from blood vessels by applying constant or time varying magnetic or electrical fields. In one embodiment a system includes winding configurations positioned about a central axis along which a body region may be placed. Each winding configuration generates a magnetic field in a direction which passes through the body region. A first winding configuration generates a first magnetic field component perpendicular to a second magnetic field component generated by a second winding configuration. In a related method for removing a deposit of plaque from a position along a wall of a blood vessel a magnetic field is applied which has a net direction predominantly orthogonal to the direction of the flow of blood through the vessel.

    Abstract: A configuration of a plurality of elongate, axially-magnetized curvilinear permanent magnets having high length to cross-section ratio, produced, for example, by the PM-Wire manufacturing process, that produce an electric machine permanent magnet rotor structure with a very low intrinsic demagnetizing field, allowing for operation at high temperature, at high RPM, or enabling use of permanent magnets comprising low coercivity magnetic materials. Exemplary embodiments of two-pole, four-pole, six-pole and eight-pole rotor permanent magnet configurations for single and dual rotor applications. The novel configuration of axially-magnetized curvilinear permanent magnets reduces demagnetization at high temperature, increases electric machine power density, reduces weight by eliminating the need for back iron, increases motor reliability, reduces manufacturing costs, and enables higher electric motor torque and electric generators. Electric machines, rotors and magnets of the invention may contain no rare earth magnetic materials.
