    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.

    Abstract: In some embodiments, a system includes multiple coils of a multi-phase machine in which the coils are each associated with a different phase. Associated with each coil is a protective element such that each protective element is associated with a different coil. When its associated protective element is in a first configuration, a coil is part of an electrical circuit, and its associated protective element allows a first amount of current to flow through the coil. Its associated protective element allows a second amount of current to flow through the coil when its associated protective element is in a second configuration. When in the second configuration, the coil's associated protective element does not obstruct current flow through other coils that are not associated with the protective element.

    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.
