Embodiment Construction

[0012] figure 1 It is the structure diagram of the vertical axis wind power generating set with disk-type magnetic levitation outer rotor 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 upper end cover, and is an important part for converting wind kinetic energy into mechanical rotational energy of the generator rotor. figure 1 The wind turbine shown in the picture is only one of the wind turbines, that is, the Darrieus type wind turbine, and the wind turbine can also have many other forms, such as H type, S type, wind turbine, etc. Cup type, Fleiner type, or their compound type. The specific location where the wind turbine is installed depends on the specific form and structure of the wind turbine. For example, it can be installed directly on the upper or lower end cover, or on the side. In the figure, it is connected to the upper end cover. The platform is indir...

Abstract

The invention discloses a disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit which combines characteristics of Japanese coreless disk-type generators, a plurality of Chinese vertical shaft disk-type inner rotor generators and repulsion-type magnetic suspension vertical shaft disk-type generators and integrated and innovated on the basis of the characteristics. The disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit is innovated in that the disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit is a suction-type magnetic suspension vertical shaft wind-driven generator unit which is material-saving and low in cost compared with the repulsion type. No extra power supplies and controllers are needed to achieve self-adaptive balance, and accordingly the disk-type magnetic suspension outer rotor type vertical shaft wind-driven generator unit is high in cost performance and promising in market prospect.

Description

technical field [0001] The invention belongs to the technical field of synchronous generators, and specifically proposes a permanent disk type (axial magnetic field) generator structure with a quasi-magnetic levitation function. Background technique [0002] In the field of wind power generator technology, the generator is an electromechanical energy conversion device that is indispensable for converting mechanical energy into electrical energy. In order to obtain more energy from the wind, how to reduce the bearing friction force becomes the key to improve the performance of the wind turbine under the premise that the wind turbine is determined. It is hoped that the generator has lower mechanical noise, higher electromechanical efficiency, smaller mechanical resistance, longer operating life, and minimum starting resistance torque, and the magnetic levitation structure becomes the preferred solution. [0003] A wind turbine with a magnetic levitation function can obtain ma...
