Abstract
The invention relates to an aerogenerator, in particular to an aerogenerator with a double-layer rotor structure. By improving the rotor structure of a dynamo so as to further optimize the field distribution on a coil movement locus, the aerogenerator greatly improves the magnetic flux passing through a coil so as to improve the efficiency of the dynamo. The aerogenerator comprises a rotor, a stator and a crankshaft. The rotor comprises an annular two-layer structure keeping certain interval, i.e. the two layers are a rotor outer layer and a rotor inner layer which together form a recessed U-shaped annular groove. The surfaces of the rotor outer layer and the rotor inner layer, which are opposite to each other, are respectively provided with outer magnetic sheets and inner magnetic sheets.The coil fixed on the stator is clamped in the recessed annular groove.
Description
Technical field
The present invention relates to a kind of wind-driven generator, particularly have the wind-driven generator of two-level rotor structure.
Background technology
Traditional wind-driven generator is made up of a group rotor and one group of stator usually, and rotor rotates under the drive of wind-force, and coil cutting magnetic line produces electric current.The magnetic field that this individual layer rotor magnetic sheet structure produces is made up of many similar annular distribution magnetic lines of force.When coil moved in such magnetic field, its efficient was lower.
Summary of the invention
The present invention is through the structure of the rotor of improvement generator, and then the Distribution of Magnetic Field on the optimization coil movement track, increases substantially the magnetic flux through coil, thereby improves the efficient of generator.Characteristic of the present invention is: the rotor of wind-driven generator comprises an annular double-layer structure at a distance of a determining deviation, rotor outer layer and rotor inner layer, and they constitute the annular groove of the U font of a depression; Be separately installed with outer magnetic sheet and internal layer magnetic sheet in rotor outer layer and rotor inner layer surface in opposite directions; Be fixed on coil clamp on the stator in the annular groove of this depression.The epitrochanterian magnetic sheet of ectonexine matees in pairs, and the polarity of two faces that magnetic sheet is relative is opposite.
Through comparison diagram 1 and Fig. 2, can be clear that the difference in these two kinds of magnetic fields that rotor structure produced.Among Fig. 2, though the magnetic field of the magnetic field in the outside of ectonexine magnetic sheet and individual layer rotor is similarly, the magnetic field between the ectonexine, just coil in fact the part magnetic field of process, its magnetic line of force is perpendicular with the movement locus of coil basically.Because adopted the ectonexine magnetic sheet structure of pairing, when coil moved in such magnetic field, magnetic flux was obviously than many greatly in the magnetic field of Fig. 1.The optimization in the magnetic field that beneficial effect of the present invention is to be brought through the two-level rotor structure just can effectively improve the generating efficiency of wind-driven generator.
Optimize structure as a kind of, the width along circumference of the ectonexine magnetic sheet of described two-level rotor is directly proportional with the distance of magnetic sheet to the generator arbor, or approaches direct ratio.The ectonexine magnetic sheet is approaching identical with respect to the subtended angle size in arbor axle center in other words.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present invention is described.
Among Fig. 3; Rotor 1 is connected on the arbor of generator; Rotor 1 comprises an annular double-layer structure at a distance of a determining deviation: rotor outer layer 12 and rotor inner layer 14, they constitute the annular groove of the U font of a depression, are separately installed with outer magnetic sheet 20 and internal layer magnetic sheet 40 on their surfaces in opposite directions.The coil 30 that is fixed on the stator 3 just is clipped in the annular groove of this depression; Leave certain clearance between coil 30 and the epitrochanterian ectonexine magnetic sheet, to guarantee rotating freely of rotor.Stator 3 is fixedly connected with casing, and casing has omitted in Fig. 3.
When rotor rotates under the drive of the fan blade that links to each other with arbor 6, coil 30 just and the magnetic field between the ectonexine magnetic sheet produced relative motion.Coil cutting magnetic line, thus electric current produced.
Fig. 4 be the edge A-A vertical with arbor to generator internal structure cutaway view.Rotor outer layer 12 has constituted outer field big ring with outer magnetic sheet 20; Constituted the little ring of internal layer when rotor inner layer 14 and internal layer magnetic sheet 40; And coil 30 is clipped between the inner and outer ring.
Magnetic sheet is evenly distributed on the rotor for ease, on rotor outer layer 12, is distributed with projection 11 equably.Likewise also similar structure can be arranged on the rotor inner layer.
What Fig. 5 showed is the ectonexine magnetic sheet dimension scale of optimizing.With respect to the axle center of arbor 5, outer magnetic sheet 20 has identical subtended angle ω with internal layer magnetic sheet 40, that is to say that they are directly proportional with their distances to the axle center along the arc length of circumference separately.
