Description
Technical field
The utility model relates to a kind of wind-driven generator, particularly a kind of vertical-shaft aerogenerator for wind and solar hybrid generating system.
Background technology
When existing wind-driven generator is used for wind and solar hybrid generating system, what usually adopt is the structure of magnetic direction and axes normal.The HY-400W wind-driven generator that the red hawk in Guangzhou as current Technical comparing maturation produces and the FD2-500 permanent-magnetic wind driven generator that Huaian, Jiangsu produces, be the structure of magnetic direction and axes normal.The permanent-magnetic wind driven generator unilateral magnetic force of this structure is large, and leakage field is many; Stator winding embeds according to certain rules in iron core slot simultaneously, because of slot effect during motor rotation, electromagnetic torque can produce pulse, thus the permanent-magnetic wind driven generator rated wind speed of this structure all higher (10 ~ 12m/s), fan blade diameter is bigger than normal, under general wind speed (being less than 5m/s), power output is little, and can not effectively utilize the material (copper cash, silicon steel sheet) of wind energy and unit, utilization ratio is low.
Utility model content
The utility model aims to provide that one can export larger power, is suitable for that wind speed range is wide in low wind speed, little air quantity situation, running efficiency and all high permanent-magnetic wind driven generator of stock utilization.
At low wind speeds, when generator number of poles is abundant, enough hour of the ratio of motor axial length and external diameter, the torque of motor in axial magnetic field (magnetic direction and axis being parallel) and the large of power density ratio conventional radial magnetic field electric motor.The stators and rotators of wind-driven generator is disc, and stator is in inner side, and rotor adopts two disks, and symmetrical placement outside stator, three disks are connected by main shaft.Make wind-driven generator have more symmetry with the magnetic pull between elimination dish and dish, and obtain larger air gap area to increase power output.
The utility model adopts two-spool axial magnetic field structure, comprises main shaft, stator (telophragma) and two rotors (two external dishes) rotated that are connected, is commonly referred to as internal stator structure.The feature of this structure is that stator both sides face two N magnetic poles, and thus magnetic flux along the circulation of stator yoke circumference, must be called for short NN-Torus type structure.
The stator of iron-core-free axial magnetic field is injection molded by winding.Because stator is iron-core-free structure, the magnetic pull between stator, rotor is corresponding less, is suitable for breeze start-up, low wind speed generating.Rotor is made up of neodymium iron boron (NdFeB) permanent-magnet steel and rotor core, for the purpose of firmly, is generally screwed on rotor core by permanent-magnet steel, then uses glass fiber tape colligation.For reducing rotor core loss, adopt silicon-steel sheet coiled around or laminate and make iron core.
Under normal circumstances, the overall performance of birotor axial magnetic field permanent magnet motor (AFPM) is better, what the utility model adopted is stator without iron core fluting birotor APFM structure (NN-Torus type), the stator yoke of this motor is comparatively large, and the magnetic flux produced because there being two rotor magnetic poles is by it.Stator yoke length is an important parameter, and it not only affects the weight of motor, also can have influence on iron loss, but it can use the square back-to-back winding (Circular Winding) of copper factor high (about 80%).This winding construction is simple, can be looped around on iron core uniformly, pitch can be selected flexibly to improve electromotive force and magnetomotive force waveform; Coil dimension is identical, is convenient to manufacture; More parallel branch can be formed; End shape is neat; Be conducive to heat radiation and increase mechanical strength; Another advantage of back-to-back winding is that the end of winding is very short, therefore significantly reduces the projecting height of winding overhang, improves power density and the efficiency of motor.
The utility model AFPM vertical-shaft aerogenerator in low wind speed, little air quantity situation, can export larger power, is suitable for the wide ranges of wind speed, is a kind of wind-driven generator being applicable to wind and solar hybrid generating system.
Accompanying drawing explanation
Fig. 1 is the NN-Torus type structural representation of the utility model AFPM wind-driven generator.
Fig. 2 is the NS-Torus type structural representation of the utility model AFPM wind-driven generator.
In figure: 1-rotor core (top); 2-permanent-magnet steel; 3-Stator Slots; 4-stator yoke; 5-rotor core (bottom); 6-winding conducting wire.
Embodiment
As shown in Figure 1, NN-Torus type stator is iron-core-free structure, is injection molded by winding.Stator offers groove portion 3, the embedded square lead 6 processed of groove, the magnetic line of force in magnetic field forms loop along rotor core 1 and 5, stator yoke 4, permanent-magnet steel 2 adopts rare-earth permanent magnet Nd FeB (neodymium iron boron) material, be separately fixed on rotor core 1 and 5 with screw, or adopt epoxide-resin glue to fit tightly.When wind wheel drives rotor to rotate, wire 6 cutting magnetic line of stator winding and induced potential, connections in, load just can send electric.
Corresponding with NN-Torus scheme, also can adopt the NS-Torus scheme shown in Fig. 2.The feature of this kind of structure has shorter stator yoke, thus improves power density and reduce the wastage, but in order to produce torque, can not Circular Winding be used, must with the low lap winding of copper factor, and the end of winding is longer, cause the external diameter of motor to strengthen, the utilance of effective material declines to some extent.In a word, the motor performance of these two kinds of versions is more or less the same, and can select as the case may be.
