摘要： 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.

摘要： An axial air-gap motor stator and a fan thereof includes a motor stator. The motor stator includes multiple metal substrates stacked together. Each metal substrate has a port and multiple pole teeth disposed around the port. The two adjacent pole teeth on each metal substrate are disposed with a magnetic pole and the number of the pole teeth of each metal substrate is a natural number twice the number of the magnetic poles of each metal substrate. The magnetic poles of the metal substrates are arranged in a staggered manner. This avoids the problems of interference of magnetic poles and prevents the magnetic field from being affected.

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.
