Flux switching type magnetic-concentration transverse flux permanent magnetic wind generator

Abstract

The invention relates to a flux switching type magnetic-concentration transverse flux permanent magnetic wind generator, in particular to a novel high-performance and direct-driving type transverse flux permanent magnetic wind generator. The generator comprises a stator, a rotor, permanent magnets and a winding. The stator consists of a plurality of stator cores (1) and an armature winding (5), wherein the stator cores (2) are distributed around the rotor. Two adjacent stator cores (1) in the circumferential direction are arranged in bilateral symmetry, and the stator cores are arranged on a casing (7) made from non-magnetic conductive material. Rotor cores (4) are arranged on a barrel (8) made from the non-magnetic conductive material. The barrel is connected with a motor rotary shaft (6), and is connected with a motor casing (7) through a bearing (9). Both sides of the rotor cores (4) are respectively embedded into permanent magnets (2) and (3), and the pole directions are opposite.The pole directions of the permanent magnets (2) and (3) of two adjacent rotor cores (4) in the peripheral direction are opposite. According to the motor structure, the single-phase generator can be manufactured, and the multiple-phase generator also can be manufactured.

Description

technical field [0001] The invention relates to an improved generator, in particular to a magnetic flux switching type magnetic flux gathering transverse flux permanent magnet wind power generator in the field of high performance and direct drive. Background technique [0002] The intensification of the energy crisis restricts the improvement of the global economy and threatens the sustainable development of human society. The vigorous development and utilization of new energy and renewable energy has become an important part of the energy development strategy of most countries in the world. Compared with other forms of renewable energy, wind power has the highest maturity and the best economy. By 2010, the total installed capacity of wind power in the world will reach 230GW, and about 10GW in China, with a rapid development momentum and broad prospects for development and utilization. Wind generator (Wind Generator) is the key core equipment of wind power system, and its e...

Problems solved by technology

[0004] In recent years, although many institutions at home and abroad have done a lot of research work on transverse flux generators, there are still some problems that need to be improved and solved.

In the existing transverse flux permanent magnet motor, two sets of adjacent rotor cores only correspond to one set of stator cores, the space utilization rate of the magnetic flux is low, the effective length ratio of the winding is not high, and there is still room for improvement in the torque density
