Abstract
The utility model discloses a vertical shaft iron-core-free disc type wind driven generator which comprises a spindle and two motor discs connected with the spindle through bearings. A stator wound with coils is arranged between the two motor discs and is fixedly connected with the spindle, permanent magnets are arranged on inner lateral disc bodies of the two motor discs, and the stator is formed by precisely die-casting multiple layers of coils through polymer composite materials. The vertical shaft iron-core-free disc type wind driven generator adopts the stator formed by precisely die-casting the multiple layers of coils through the polymer composite materials, thereby greatly narrowing gaps between the stator and the permanent magnets, improving generating efficiency and enabling the overall structure of the generator to be compact.
Description
Technical field
The utility model relates to a kind of wind-driven generator, relates in particular to the vertical axis coreless disc type wind-driven generator.
Background technology
The vertical axis coreless disc type wind-driven generator is a kind of new special motor of representing the electromechanics trade future thrust, is the rare earth permanent magnet generation technology that adopts no iron core, brushless, no magnetic damping.Generally through directly casting stator profile, winding around constitutes existing its stator of vertical axis coreless disc type wind-driven generator then.The stator relative shape of this kind structure is complicated, and stator dimensions precision is relatively poor.
China's utility model patent patent No. 201020516615.7 discloses a kind of vertical axis coreless disc type wind-driven generator; Comprise the shell formed by upper casing and lower casing, be loaded on the dead axle on the shell and be installed in the winding on the dead axle; Wherein between dead axle and the shell bearing is housed, said upper and lower shell inwall is fixed with upper and lower yoke respectively, is fixed with upper and lower magnet steel on the upper and lower yoke respectively; Between winding and the upper and lower magnet steel bearing holder (housing, cover) is arranged, said winding is distributed winding.This kind wind-driven generator is not mentioned the technical clarification that how to improve the stator dimensions precision.
Summary of the invention
The utility model provide a kind of simple in structure, dimensional accuracy is high, start the low vertical axis coreless disc type wind-driven generator of wind speed requirement.
A kind of vertical axis coreless disc type wind-driven generator; Comprise that main shaft and bearing connect two electric discs of main shaft; Be provided with the stator of multilayer power coil between two electric discs; Stator is fixedly connected main shaft, is equipped with permanent magnet on two inboard disk bodies of electric disc, and described stator passes through polymer composite microdiecast moulding by lattice coil.A kind of no iron core stator of function admirable is not only by the stator that this kind adopts polymer composite microdiecast lattice coil to form and the overall dimension of its stator obtains accuracy to greatest extent, has dwindled gap between stator and the permanent magnet greatly and has improved generating efficiency and make the whole generator structure compact more.
The inboard disk body of described two electric discs is through mounting blocks adhesive permanent magnetism body, and mounting blocks is connected through bolt with electric disc.A plurality of permanent magnets in described two electric discs in each electric disc, the mutual polarity opposed alignment of two adjacent permanent magnets, two mutual polarity of permanent magnet that are oppositely arranged in two electric discs are provided with on the contrary, to improve the generating efficiency of wind-driven generator.
For the installation rate that improves the utility model generator is provided with the blade of integrally casting in the described electric disc outside, exempt traditional bolted split type blade.The blade of integrally casting has also improved the whole fastness of electric disc simultaneously, and reduces the weight raising generating efficiency of whole generating machine.
Described blade one end is positioned on the electric disc disk body, and the other end stretches out electric disc disk body external diameter to obtain best wind energy.
The stator that the utility model adopts polymer composite microdiecast lattice coil to form has dwindled gap between stator and the permanent magnet greatly and has improved generating efficiency and make the whole generator structure compact more.
