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 with low coercivity fields. 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. Typical applications of the axially-magnetized curvilinear permanent magnets, rotors, and electric machines of the invention are in motors for electrically-powered ground vehicles, rotorcraft, airplanes and other aircraft.

Abstract: A slotless rotating electric machine includes a rotor having multiple alternating polarity permanent magnets that drive magnetic flux back and forth across a magnetic airgap formed with a radial airgap surface of a slotless ferromagnetic stator. The stator includes a helical backiron formed from a ferromagnetic strip wound edgewise and extending axially, and an adhesive film on the radial airgap surface of the backiron. Armature windings of wire having individually insulated twisted strands diametrically enveloped by an outer serve are adhered to the adhesive film. The adhesive film holds the said serve to the backiron and the serve holds the strands to the adhesive film. The armature windings are in an air core winding pattern formed directly onto the adhesive film in a one wire radial layer that is only one wire deep where inside the magnetic airgap, and having end turns of multiple phases overlapping. The armature windings pressed into said adhesive film as a group after they are formed and adhered while the adhesive cures, such that the wire is both bonded to said radial airgap surface of said helical stator backiron and is additionally partially embedded in the adhesive film.

Abstract: An electrical system including a linear motor in which energized forcer and thruster coils are used for the field and armature elements. In accordance with exemplary embodiments, one or more thruster coils may be provided on a shaft with opposing single or multiple fixed forcer coils. Using coils as the electromagnets for forcer and thruster coils advantageously provides necessary power while also minimizing system weight and decreases in magnetism typically encountered with permanent magnets with rising temperature, resulting in higher and more controllable magnetic forces over varying temperatures. Ferrous elements, such as a ferrous system housing and/or open ferrous containers for the thruster coils may be further included to advantageously focus the magnetic forces. Additionally, multiple forcer and thruster coils may be disposed in various arrangements along the shaft. Exemplary applications include use of such a system for controlling oscillations of a poppet valve in an internal combustion engine.
