摘要： This application relates to manufacturing techniques for producing thin magnetic elements. In particular, the manufacturing processes are designed to accommodate the mechanical properties of sintered magnetic substrates. One of the manufacturing processes involves cutting a magnetizable substrate into a number of slices and adhesively coupling the slices to a sheet that can take the form of a layer of grinding tape. After concurrently grinding a first surface of each of the slices, the slices are flipped over so that the first surface of each slice is attached to another layer of grinding tape. A second surface of each of the slices is then ground until a desired thickness is achieved. Subsequent to the grinding, dicing operations can be applied to the slices to produce magnets having a desired length and width.

摘要： 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.

摘要： An improved magnetic generator has been developed that is particularly suitable for creating modular micro wind turbines, although other power generation applications are contemplated. The generator utilizes a series of rotors with axially aligned magnets on each side of the rotor face. As a drive shaft rotates the rotors in proximity to stators, a magnetic flux and electricity is generated. In certain embodiments, the rotors utilize magnet pockets to stabilize the magnets. In the preferred embodiments, layers of magnets are placed in each magnet pocket to achieve magnetic amplification by having multiple magnets, and their respective fluxes, influence the stators.
