    Abstract: A conductor assembly and method for constructing 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 embodiment the method includes providing a first insulative layer having a curved surface along which a conductor segment may be positioned, and forming a channel in the insulative layer, which defines a first conductor path. The channel includes first and second opposing channel surfaces each extending from the surface of the insulative layer into the insulative layer and a third channel surface extending between the first and second channel surfaces. Each of the first and second channel surfaces includes a substantially flat surface portion with the surface portion of the first channel surface parallel with the surface portion of the second channel surface. A first segment of conductor is placed in the channel.

    Abstract: A conductor assembly and method for constructing 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 embodiment the method includes forming a structure comprising layers of material extending along a first aperture path. The structure includes multiple concentric layer surfaces. A channel is formed in each of the layers of the material and along each of the multiple surfaces. Conductive material is positioned in each channel to provide a spiral configuration. The surfaces of multiple ones of the layers are of tubular shape. The layers of material are sequentially positioned one over another and about an axis along which first and second opposing coil end regions are formed. The layers are formed with a region of a first thickness and a shoulder region. The shoulder region is alternately formed in the sequence at one coil end region or at the other coil end region. Each shoulder region has a greater thickness than the first thickness.

    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 continuous method of manufacturing permanent magnets and the permanent magnets created thereby. A fine powder is created from a combination of magnetic metals. The powder (a metal alloy) is placed in a non-magnetic container of any desired shape which could be, for example, a tube. The metal alloy and tube are swaged while a magnetic field is applied. Once swaging is complete, the metal alloy and tube are sintered and then cooled. Instead of sintering, a bonding agent can mixed into the powder. Following cooling, the metal alloy is magnetized by placing it between poles of powerful electromagnets with the desired field direction. The process of the invention enables mass-produced, cost-effective PM products, which are more robust, easily assembled into products, enables new “wire like” shapes with arbitrary magnetization direction. The process enables mass production of permanent magnets of any desired cross section, produces permanent magnets continuously that may be cut to any length, and may, in an embodiment, result in directional magnets.

    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: Microemitter arrays comprising a plurality of microemitters having current transfer features such as microtips or blades to form contactless current transfer structures, and homopolar machines comprising same, are described and claimed. The invention further defines homopolar motors or generators comprising electrical connections formed of electrodes that transfer current without mechanical contact. Micron-size electron field emitters offer contact-free current transfer with high longevity, high reliability and are insensitive to temperature and if needed ionizing radiation. The microemitters may comprise diamond material and may be placed in a vacuum or noble gas environment. The gap between microemitters and electrodes for efficient, reliable current transfer could be in the range of 0.5 to 2 mm. The current transfer can be accomplished without mechanical contact, enabling higher RPM motors than previously achievable with brush or liquid metal electrical connections.

    Abstract: An electrical system having a current path formed in a region between first and second electrodes. When a low pressure is sustained in the region, and a plasma is generated in a portion of a gap between the electrodes, current flows across the gap from the first electrode to the second electrode. In one embodiment the system is operable as a motor or a generator, having a first electrode and a member including a second electrode which is rotatable with respect to the first electrode. In another embodiment a first conductor is positioned to carry current toward or away from a first terminal at a high temperature, and a second conductor is spaced apart from the first terminal to carry current toward or away from a second terminal when the second conductor is at a low temperature relative to the temperature of the first region.
