Existing non-permanent magnetism small power generation machine rotor generally is made up of magnet steel or lamination magnet steel and lead line bag, and it need add staring torque and could work.And according to the characteristic of permanent magnetic material, the permanent magnetic material that with the rare-earth Nd-Fe-B is representative is after magnetizing, no longer need external energy, just can set up powerful magnetic field at its surrounding space, brought brand-new theory and practice for design, the production of motor, generator, produce novel rotor of permanent-magnetic power generator structure thus, substituted incompatible non-permanent magnetism small power generation machine rotor.And the novel permanent magnetic generator rotor structure has the wind-driven generator of adaptation again at performance requirements such as high-altitude installation, use and the non-magnetic conductions of countershaft as the permanent-magnetic wind driven generator rotor.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of performance requirement that both can satisfy the non-magnetic conduction of permanent-magnetic wind driven generator rotor countershaft, can adapt to the high-altitude again, install and use requirement, and it is simple in structure, easy to manufacture, easy maintenance, use cost is low, energy-saving and cost-reducing, the colyliform low-speed permanent-magnet wind power generator rotor of suitable breeze wind.
For achieving the above object, a kind of colyliform low-speed permanent-magnet wind power generator rotor, it forms rotor matrix by wheel rim, spoke and the wheel hub of non-magnetic conduction, on the wheel rim of rotor matrix periphery, embed the magnetic guiding loop and the magnetic tile fragment of adaptive thickness, the flat key of configuration connection rotating shaft in the wheel bore in week in rotor matrix.
For implementation structure optimization, its further step also has:
Spoke is 6 supporting ribs.
The magnetic tile fragment is the permanent magnet tile fragment.
Wheel rim is an aluminium alloy wheel rim.
The utility model adopts forms rotor matrix by wheel rim, spoke and the wheel hub of non-magnetic conduction, on the wheel rim of rotor matrix periphery, embed the magnetic guiding loop and the magnetic tile fragment of adaptive thickness, configuration connects the technical scheme of the flat key of rotating shaft in the wheel bore in week in rotor matrix, has solved existing rotor of permanent-magnetic power generator structure and need overcome difficult point at performance requirements such as high-altitude installation, use and the non-magnetic conductions of countershaft.
The beneficial effect that the utility model colyliform low-speed permanent-magnet wind power generator rotor is had compared to existing technology:
(I) form the basal body structure of rotor with the wheel rim of non-magnetic conduction, spoke and wheel hub, satisfied the performance requirement of the non-magnetic conduction of permanent-magnetic wind driven generator rotor countershaft, improved product quality;
(II) from heavy and light, be fit to that install in the high-altitude, instructions for use, safe and reliable and saved raw material, reduced product cost, improved efficiency of installing software;
(III) the spoke structure of being made up of several supporting ribs has reduced the requirement to starting torque, is fit to breeze wind, has improved the product operating efficiency;
(IV) simple in structure, easy to manufacture, easy maintenance, use cost is low, and is energy-saving and cost-reducing, is convenient to penetration and promotion.
The utility model is fit to do all kinds of small-sized low-speed permanent-magnet wind-driven generator of breeze rotor of permanent-magnetic power generator.
Below in conjunction with drawings and Examples the utility model is further described.
