Problems solved by technology

However, after adding the usual full magnetic levitation device, the cost of the entire wind turbine will increase and the cost performance will decrease, which will increase the cost of power generation and is not conducive to the popularization and application of wind power generators. Therefore, it is necessary to develop a new structure with high cost performance and low cost. dynamo

Embodiment Construction

[0010] figure 1 It is a schematic cross-sectional structure diagram of the disk-type magnetic levitation inner rotor type vertical axis wind power generating set of the present invention. The structure of the generator in the present invention can be seen clearly from the figure. The wind turbine (7) is installed on the rotating shaft (3), and is an important part for converting wind kinetic energy into mechanical rotational energy of the rotating shaft (3). figure 1 The wind turbine shown in the figure is only one type of wind turbine, that is, the H-type wind turbine, and the wind turbine can have many other forms, such as S-type, wind-cup type, Darrieux type, etc. type, Fleiner type, etc., and may also be a composite type of these models. The proper location for installing the wind turbine depends on the specific form and structure of the wind turbine.

Abstract

The invention relates to a disc magnetic levitation inner rotor type vertical axis wind generating set which is an integrated innovation formed by combining the characteristics of a Japan generator without a core disc, varieties of vertical axis type inner rotor generators and varieties of repulsive magnetic levitation vertical axis disc type generators in China. The disc magnetic levitation inner rotor type vertical axis wind generating set is characterized by being a suction type magnetic levitation vertical axis wind generating set; compared with a repulsive generator, the suction type magnetic levitation vertical axis wind generating set can save material and is low in cost; furthermore, an extra power supply and a controller are unnecessary; that is to say, self-adaptive balance can be realized; therefore, the wind generating set has higher cost performance and a wider market prospect.

Description

technical field [0001] The invention belongs to the technical field of synchronous generators, and specifically proposes a permanent disk generator structure with a magnetic levitation function. Background technique [0002] In the field of wind power generator technology, the generator is an indispensable electromechanical energy conversion device that converts mechanical energy into electrical energy. In order to get more energy from the wind, under the premise of determining the wind turbine, it is hoped that the generator has lower mechanical noise, higher electromechanical efficiency, smaller mechanical resistance, and longer operating life. [0003] A wind turbine with a magnetic levitation function can obtain many of the above-mentioned advantages at the same time. However, after adding the usual full magnetic levitation device, the cost of the entire wind turbine will increase and the cost performance will decrease, which will increase the cost of power generation a...
