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.

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: A flux directed magnet and a method of manufacturing a flux-directed magnet in a reduced number of process steps is described and claimed. The present invention is, in an embodiment, a single-step manufacturing of flux directed magnet assemblies such as, but not limited to, Halbach arrays of arbitrary multipole order. Even tube-shaped flux directed magnet assemblies such as Halbach arrays with large aspect ratio, i.e. length to diameter, can be produced in single steps using the method of the invention. Alternatively, the present invention may be one step of a plurality of steps in a process for manufacturing of flux directed magnet assemblies.

Abstract: A power conversion and distribution system. In one embodiment low voltage source components convert a high voltage AC power source to a relatively low voltage supply and provide a direct current output. First superconductor wires carry current from the low voltage source components to a load, and second superconductor wires carry current from the load to the low voltage source components. Individual ones of the first wires are grouped with individual ones of the second wires so that wires connected to carry current in opposite directions are in such sufficiently close proximity that additives of self-fields generated by individual ones of the wires during power transmission result in reduction of the magnetic fringe field generated, thereby increasing the current carrying capacity of the wires.
