Abstract

The invention provides a coaxial birotor general wind generator which comprises a bracket which is arranged on a tower post and can freely rotate around a vertical axis in the tower post, a ram head is arranged above the bracket, and one side of a stander is provided with a wind helm. The ram head consists of a main shaft, an outer casing shaft, two wind wheels, a magnetic steel rotor and a coil rotor, wherein, the outer casing shaft is sheathed at one end of the main shaft, the main shaft and the outer casing shaft are arranged on the bracket through bearings, the wind wheel I is fixed on the main shaft, the wind wheel II is fixed on the outer casing shaft, the magnetic steel rotor is fixedly arranged on the main shaft, and the coil rotor is fixedly arranged on the outer casing shaft. The coaxial birotor general wind generator has high working efficiency, good stability and small occupied area of equipment, and can be placed in courtyards, the tops of buildings or roofs, gazebos and other places; and the generator has the advantages of simple and convenient installation, high feasibility, low cost, simple structure, convenient production and maintenance, and the like.

Description

Coaxial dual rotor general wind turbine (1) Technical field The invention relates to a generator, in particular to a wind power generator. (2) Background technology There are many public reports about wind power generators. For example, the Chinese patent application number is 200620151724.7, which is named "Serial Double Rotor Wind Power Generator and Its Variable Speed ​​and Frequency Excitation System"; the application number is 200620167795.6, which is named "Dual Rotor Generator" Technical solutions disclosed in patent documents, etc. The above-mentioned existing series-type dual-rotor wind-driven generator just changes the operation mode of the generator, and its internal structure is not much different from that of a common generator, and there is no improvement in the internal heat dissipation of the generator. Complicated in processing and manufacturing technology does not have economical and practical effect. The coaxial dual-rotor general-purpose wind turbine ...
