Description
Technical field
The present invention relates to wind-driven generator.
Background technology
Wind-driven generator adopts and is independent of the outer additional cooling system of motor in the prior art; Additional cooling system structure is complicated, raw material and manufacturing cost, and motor weight is big, installs because of difficulty.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of wind-driven generator structure, and cooling system structure is simple, and is easy for installation, with low cost, and can alleviate motor weight.
For solving the problems of the technologies described above; The present invention adopts following technical scheme: wind-driven generator structure comprises stator and is located at the rotor of stator inner circumferential side that stator is installed on the stator support; Rotor comprises magnetic pole; Magnetic pole is installed on the rotor field spider, it is characterized in that: said stator support comprises the annular blast pipe that the middle part is provided with, and said annular blast pipe inner circumferential side is provided with at least one air inlet; Ring annular blast pipe outer circumferential sides is the supporting traverse in eight double as air channels of radial even distribution, and said supporting traverse rear portion is provided with air outlet.
Preferably, the ventilation duct by annular between the supporting traverse of said stator support is communicated with, and said air outlet is evenly distributed on the ventilation duct.
Preferably, the supporting traverse end of said stator support is provided with fixing lug boss and is connected with electricity generator stator stand.
Preferably, the magnetic pole of said rotor adopts the oblique electrode structure of " people " font, and magnetic pole direct screening during with the rotor yoke installation.
Preferably, the electromagnetic wire of said stator adopts enamel insulated round copper wire and adopts the embedding of loosing continuously.
The present invention is because air pipe and stator support are one, and nothing is independent of the additional cooling system outside the generator, and is simple in structure, good cooling results, and generator in light weight, cost is low.

Embodiment
Specify wind-driven generator structure of the present invention with reference to figure 1,2,3,4,5,8,9,10; Comprise stator 2 and be located at the rotor 3 of stator inner circumferential side; Stator is installed on the stator support 1, and rotor comprises magnetic pole 33, and magnetic pole is installed on the rotor field spider 31; Said stator support comprises the annular blast pipe 11 that the middle part is provided with; Said annular blast pipe inner circumferential side is provided with at least one air inlet 12, and ring annular blast pipe outer circumferential sides is the supporting traverse 13 in eight double as air channels of radial even distribution, and said supporting traverse rear portion is provided with air outlet 16.Ventilation duct 14 by annular between the supporting traverse of said stator support is communicated with to get up, and said air outlet 16 is evenly distributed on the ventilation duct.The supporting traverse end of said stator support is provided with fixing lug boss 15 and is connected with electricity generator stator stand.
As shown in Figure 7, prior art rotor magnetic pole adopts directly and extremely tiltedly hangs; The straight extremely tiltedly hanger of rotor magnetic pole has certain limitation, if electric machine stator iron is long, makes that then the heat radiation two ends of motor are inhomogeneous, influences the operational reliability of motor; Simultaneously, because magnetic pole receives one-sided wind resistance in running, the discontinuity of bearing can cause bearing temperature rise too high, thereby influences the useful life of bearing.As shown in Figure 6, the magnetic pole that the present invention can rotor adopts the oblique electrode structure of " people " font, and magnetic pole direct screening during with the rotor yoke installation.Because rotor magnetic pole adopts the oblique electrode structure of pole shoe " people " font, when rotor rotates, makes the air-flow in the motor gas-gap be uniformly distributed in the magnetic pole two ends, make Temperature Field for Electric more become balanced, be beneficial to the stable operation of motor.Simultaneously, because magnetic pole suffered axial wind resistance in running is uniformly distributed with towards both sides, the suffered load of bearing will alleviate like this, thus the useful life of director's bearing.
In the prior art, stator winding adopts the flat electromagnetic wire.Because the production technology of present domestic flat variable-frequency electromagnetic line is immature; For reaching the necessary anti-corona effect of wind-driven generator; Can only do stator coil does only single; To wind the line then, system's operation such as pull-up, integer, bag insulation, hot pressing, the production cycle is long, cost is high, technical difficulty is big; Simultaneously, can not realize not having the node wiring, thereby influence the insulation property of motor.The electromagnetic wire of said stator adopts enamel insulated round copper wire.The present invention adopts the frequency conversion enamel-cover circle electromagnetic wire that fine anti-corona effect is arranged, and need not carry out once more anti-corona insulation processing to electromagnetic wire; Because be the embedding of loosing continuously, all windings do not have intermediate node, the winding insulation structural integrity has been guaranteed the electromagnetic wire original fatigue strength, has avoided because of the issuable contact resistance of welding intercoil connection; Direct coiling in stator core, the coil manufacturing process is simple, less equipment investment, saves raw material; Winding be the minor diameter multiply and around, avoid the excessive and kelvin effect of the electromagnetic wire that produces of lenticular wire area itself, thus the raising efficiency of motor.
