Abstract
The utility model discloses a miniature power generator, aiming to provide the miniature power generator with high generating efficiency. The miniature power generator is composed of a rotor base (1), a steel ring (2), a rotor (3), a coil (4), a stator (5), a capstan shaft (6), a spacing copper sheathing (7), a bearing (8), a bottom plate (9), and a bearing seat (10). The stator (5) is formed by different silicon steels through punching and folding, and the periphery forms a magnetic line slot which forms 45 degrees angle with a folding plane. The utility model is suitable for the manual generating in an electroless area.
Description
Technical field
The utility model relates to a kind of microgenerator.
Background technology
The application of microgenerator is very extensive, as generating electricity to flashlight with it, to rechargeable battery charging etc., but there are some defectives in existing microgenerator, the formed magnetic force line cutting groove of silicon steel sheet group that forms stator is vertical with superposed surfaces, current pulsation is bigger, unstable during generating, and generating efficiency is lower.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of microgenerator is provided, during the generating of this microgenerator current pulsation little, stable, the generating efficiency height.
The technical scheme that the utility model adopted is: the utility model comprises rotator seat, steel ring, rotor, coil, the silicon steel sheet group, capstan, spacing copper sheathing, bearing, base plate and bearing pedestal, described rotor is set on the described rotator seat by described steel ring, described coil is wrapped on the described stator, described stator is fixedly installed on the described base plate by described bearing pedestal, described spacing copper sheathing is arranged between described stator and the described base plate, described bearing fixing is arranged in the described bearing pedestal, described capstan one end is fixedlyed connected with described rotator seat, the other end is arranged on the inner ring of described bearing, described stator is formed by stacking by the multi-disc punching silicon-steel, described silicon steel sheet is made up of annulus and several T font boss that are evenly distributed on described annulus outer rim, the total arc length in outer end of the described T font boss on every described silicon steel sheet equates, the both sides arc length is pressed the different proportion setting, and the described stator periphery that superimposed back forms forms the magnetic force line cutting groove that certain included angle is arranged with superimposed plane.
Described stator is formed by stacking by 7 different described punching silicon-steel, and the periphery of described stator and superposed surfaces form the magnetic force line cutting groove of miter angle, and described silicon steel sheet has 9 described T font boss.
Described rotor is made up of 12 N, S utmost point neodymium iron boron magnetic body alternately.
The beneficial effects of the utility model are: because stator of the present utility model adopts the different punching silicon-steel of multi-disc to be formed by stacking, the stator periphery forms the magnetic force line cutting groove that becomes miter angle with superposed surfaces, therefore current pulsation is little, stable when generating electricity, thereby improved generating efficiency.Because the utility model is a brushless electric machine, can produce carbon distribution, wearing and tearing coil, thereby improve life of generator again.
