Problems solved by technology

After research, it is found that this technical solution has the following defects: 1. According to this invention, because the coils of a single group of coils are relatively crowded inside the magnetic poles, it is troublesome when wiring, and the power cannot be too large. The diameter of the motor above 10KW will be large, and the amount of wire used 2. According to this invention, the magnetic material replaces the graphic design structure of the bearing, and its processing technology cannot be realized, because the polarity of the magnetic material is between the two sides of the magnetic object. The end, either vertical or horizontal, has a special-shaped design structure, which can only be realized by layering magnetic materials into multiple blocks, which is very complicated and therefore not advisable

Abstract

The invention provides a disk type permanent magnet wind-driven generator relating to a wind-driven generator and at least comprising a shell, a stator, rotors, a generator shaft and a bearing, wherein the generator shaft is arranged at a shaft axis position of the shell, two ends of the generator shaft are respectively spanned on the shell through a bearing frame, one end of the generator shaft extends out of the shell and the other end is arranged in the shell; the stator consists of stator coil brackets and stator coils, the stator coil brackets have distributed structures in radial uniform distribution, and the stator is fixed on the shell; the rotors are radially fixed on the generator shaft and arranged opposite to the stator, and an air gap is remained between the stator and each rotor. The disk type permanent magnet wind-driven generator is characterized in that the stator coil brackets are distributed in two layers and adopt a non-cross overlapped way; the stator coils in two groups are respectively wound on the surfaces of the two layers of the stator coil brackets; and the two rotors are respectively arranged at two sides of the stator. The invention has the advantages of no frication resistance, no noise, sufficient utilization of magnetic fields, small starting wind power, large generated energy and simple structure.

Description

technical field [0001] The invention relates to wind power generators, in particular axial field generators. Background technique [0002] Wind power generation is one of the clean energy sources that are relatively easy to obtain, and many kinds of axial magnetic field generators based on wind power energy have been disclosed in the prior art.
