Abstract

The invention provides a strong wind resistant small-sized wind driven generator; and the strong wind resistant small-sized wind driven generator comprises a power generator spindle, a blade, a shell, a power generator rotor and a power generator stator, wherein the blade is fixed on the power generator spindle; the shell is used for supporting the power generator spindle by a bearing; the shell comprises a stator shell as well as a front end cover and a back end cover; the front end cover is positioned at the front end of the stator shell; the back end cover is positioned at the back end of the stator shell; the power generator stator is positioned in the shell and fixed on the power generator spindle; corresponding to the power generator rotor, the power generator stator is fixed on the internal surface of the stator shell of the shell; the strong wind resistant small-sized wind driven generator is characterized by further comprising a controller and a mechanical electromagnetic brake, which are connected with each other; the mechanical electromagnetic brake is mounted on the power generator spindle; and the controller is used for controlling the mechanical electromagnetic brake to brake. The strong wind resistant small-sized wind driven generator provided by the invention cannot be forced to operate when being blown by strong wind, so that the safety of the small-sized wind driven generator is ensured.

Description

[0001] This application is an application number: 201110023582.1, application date: January 21, 2011, applicant: Zhongke Hengyuan Science and Technology Co., Ltd., name of invention: a divisional application of a small wind-driven generator with strong wind resistance. technical field [0002] The invention relates to a small wind power generator, in particular to a strong wind resistant small wind power generator. Background technique [0003] As a natural resource with abundant reserves, wind energy has been widely used and developed rapidly all over the world due to its convenient use, renewable, low cost, and non-polluting characteristics. huge. In recent years, the market of small wind turbines has also developed very rapidly, and the application areas are becoming wider and wider. However, as the global climate warms, extreme climates continue to appear. Taking China as an example, sandstorms in the north occur more frequently and more intensely every year; the probab...
