  • Publication number: 20140268460
    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.

A first electric insulator is disposed between the first side of the first conductor and a second conductor such that a difference between a voltage associated with the first conductor and a voltage associated with the second conductor defines a voltage stress therebetween. The first electric insulator providing a first degree of electrical isolation based on the voltage stress. A second electric insulator is disposed between the second side of the first conductor and a third conductor such that a difference between the voltage associated with the first conductor and a voltage associated with the third conductor defines a second voltage stress therebetween. The second electric insulator providing a second degree of electrical isolation based on the second voltage stress.

  • Publication number: 20140152136
    Abstract: In some embodiments, an electromagnetic machine includes a rotor element configured for movement relative to a stator. The rotor element includes a magnetic support, a magnetic pole assembly, and a retainer. The magnetic support is formed, at least in part, from a ferromagnetic material and is configured to be coupled to the magnetic support. The retainer is coupled to both the magnetic support and the magnetic pole assembly. The retainer is further configured to be in a first state during a first time period and a second state during a second time period, after the first time period, such that during the second time period, the coupling of the magnetic pole assembly to the magnetic support is maintained.

  • Patent number: 8736133
    Abstract: A first winding portion from a set of winding portions has a set of coils. Each coil of the first winding portion is associated with a different electrical phase from a set of electrical phases. Each coil of the first winding portion circumscribes a different area from a set of areas circumscribed by the set of coils of the first winding portion. A second winding portion has a set of coils associated with the set of electrical phases and a third winding portion has a set of coils associated with the set of electrical phases. The first winding portion at least partially overlaps the second winding portion and the third winding portion such that each area from the set of area is substantially circumscribed by a coil associated with each electrical phase from the set of electrical phases.

  • Patent number: 8397369
    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.

  • Patent number: 8362731
    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.
