GENERATOR FOR USE IN WIND TURBINES OR WATER-POWERED WHEELS

摘要

The invention relates to a generator (1), in particular for use in wind turbines or water-powered wheels with low speeds. To improve the efficiency and increase output, a disc rotor generator is disclosed, in which the corresponding magnets (7) and wound toroidal cores (4) are arranged in an axial direction, lying on a respective annulus, the central radius of said magnets and cores being approximately identical. This permits the surface that is effectively used for a magnetic flux in a generator (1) to be significantly enlarged, thus increasing the output at low speeds. The generator (1) is also constructed with a modular design, which is easy to assemble and facilitates the replacement of defective individual annulus segments (23) comprising windings (13, 14, 15) at any time. In addition, the output can be further increased by adapting the size of the toroidal core and that of the permanent magnets used, as preferably the radial surfaces of the magnets (7) and toroidal core windings are set up with a magnetic flux in the axial direction.
