Embodiment Construction

[0011] Such as figure 1 As shown, the linear permanent magnet generator for wind power generation according to the present invention includes a rotor 1 and a stator. The rotor 1 is fixedly installed on the chain 3, and the chain 3 is installed on the sprockets 4, 5. The rotor 1 is a plurality of permanent magnets fixedly installed on the chain 3. In order to facilitate a clear display, only the Three rotors are provided, and the actual situation is that the chain 3 is equidistantly covered with rotors. The stator consists of an iron core 21 and a coil. The iron core 21 has a wire groove 22, and the coil is installed in the wire groove 22. The shape of the iron core 21 is a strip parallel to the chain 3. Of course, the iron core 21 can also be designed into other shapes, such as the same ring shape as the chain 3 , or a ring shape slightly smaller than the chain 3 . What is necessary is just to be able to make the main part of the iron core 21 to which a coil is attached, and...

Abstract

The invention is to provide a linear permanent magnet dynamo with simple structure for wind power generation. The invention comprises a stator and a rotor, and is characterized in that the rotor is fixedly arranged on a chain which is arranged on a chain wheel, and the stator is fixedly arranged on one side of the chain. The rotor is a plurality of the permanent magnets which are fixedly arrangedon the chain. The stator is composed of a coil which is wound on an iron core. The invention solves the disadvantages of common dynamo, such as huge volume, high rotating speed and too few poles, andis characterized in low speed, high power and multi-pole particularly suitable for the high power wind power generators. The invention can be arranged in the wind turbine tower with no speed increasedevice equipped between the wind wheel and the generator with convenient production, arrangement and transportation.

Description

technical field [0001] The invention relates to a non-generator, in particular to a linear permanent magnet generator for wind power generation used in a wind power generation device. Background technique [0002] Wind generators use wind energy to drive the wind wheel to rotate, thereby driving the generator to run. In order to facilitate the overall installation, the generator is usually installed in the cabin at the top of the wind turbine tower. The advantage of this structure is that the wind wheel can directly drive the generator rotor to rotate, or drive the generator to rotate through the speed increaser, avoiding the mechanical loss caused by the intermediate transmission link. However, traditional generators are all cylindrical structures that rotate in a circle. This kind of generator is bulky and installed on the top of the wind turbine tower, causing the center of gravity to be unstable. In addition, for wind turbines, especially high-power wind turbines, the ...
