  • Publication number: 20190245421
    Abstract: In one embodiment, an apparatus includes a first member that supports a magnetic flux carrying member and a second member that supports a magnetic flux generating member disposed for movement relative to the first member. An air gap control system is coupled to at least one of the first member or the second member and includes an air gap control device that is separate from a primary magnetic flux circuit formed between the first member and the second member. The air gap control device is configured to exert a force on one of the first and second members in response to movement of the other of the first and second members in a direction that reduces a distance between the first and second members to maintain a minimum distance between the first and second members and/or substantially center the one of the first and second members within the other.

  • Patent number: 10256687
    Abstract: A rotor element configured for movement relative to a stator includes a backing member formed, at least in part, from a ferromagnetic material; a first magnetic pole having a first polarity; and a second magnetic pole having a second polarity, opposite the first polarity. The first magnetic pole and the second magnetic pole are coupled to a first surface of the backing member such that the second magnetic pole is disposed, relative to the first magnetic pole, at a distance defined in a direction of a width of the backing member. A thickness of the backing member is varied along the width of the backing member to form a plurality of alternating first portions and second portions. The first portions include protrusions extending from a second surface of the backing member, opposite the first surface, such that the first portions are thicker than the second portions.

  • Patent number: 10242783
    Abstract: Numerous arrangements for permanent magnets are disclosed that can focus the flux produced by the magnets. Depending on the particular application in which the disclosed designs and techniques are used, efficiency and reliability may be increased by minimizing flux leakage, increasing peak flux density, and shaping the flux fields to improve the effective coercivity of the flux focusing permanent magnet arrangement when loaded, and to achieve customized voltage and current waveforms. The disclosed magnet assemblies may be incorporated into a machine, such as a motor/generator, having windings and may be disposed for movement relative to the windings. The magnet assembly may be mounted on a support formed of one or more ferromagnetic materials, such as a back iron. The disclosed flux focusing magnet assemblies may be formed using a variety of manufacturing methods.
