Abstract
A high efficiency external rotor axial-flow type micro-generator is composed of a rotor and a stator. The rotor is composed of a rotor pedestal, a rotor shaft, magnets and rotor bearings, and the stator is composed of a stator pedestal, iron cores, stator solenoids and stator bearings. The rotor pedestal is fixed on the rotor shaft through the interference fit and rotated around the rotor shaft. The magnets are fixed on the inner surface of the rotor pedestal in the S-N pole alternating way. The stator is fixed on a shell body of the generator through the stator pedestal, the stator solenoids are wound on the iron cores and fixed on the stator pedestal with the iron cores, devices for shielding the leakage magnetic field and eliminating the eddy current inside the stator pedestal are arranged on the magnet end faces. By adopting the scheme, the magnetic leakage outside the rotor end face is thoroughly eliminated, the leakage magnetic filed will not be cut by the stator pedestal, and the eddy current will not be formed. Thus, without the eddy current heating, the efficiency and the service life of the generator are increased, and the physical consumption of operators is reduced.

Learn through market analysis; Frequent generation along with natural calamities such as earthquakes in recent years; Country has strengthened the emergent prevention input of natural calamities such as earthquake; And reliable and stable emergency service equipment has very important effect in the disaster relief is emergent, especially in, low power portable hand generator and pedal generators more and more receive people's attention.Adopt manpower to generate electricity; Generator efficiency is just very crucial; Stepping on what adopt in the generator at hand generator and pin all is outer rotor shaft streaming microgenerators, and this generator is made up of rotor and stator, and its rotor is made up of rotator seat, armature spindle, magnet and rotor bearing; Stator is made up of stator seat, iron core, stator line bag and stator bearing, specifically shown in figure (1-3).Generator unit stator is fixed, and during work, rotor is high speed rotating under the drive of gear train, and stator line bag cutting magnetic line generates electricity.Through constantly discovering, the formed magnetic field part of the magnet in rotor extends rotor end-face, has formed stray field, and shown in figure (4), this part magnetic field is not cut by stator line bag.Yet stator seat has but entered into stray field as the reguline metal, and along with the continuous cutting magnetic line of the rotation of rotor, in stator seat, has formed vortex flow, shown in figure (5).This electric current causes stator seat and generator heating, has not only expended manpower, also greatly reduces the efficient and the life-span of generator.
Summary of the invention
The utility model purpose is a kind of high efficiency outer rotor shaft streaming microgenerator of design, through managing to shield stray field, makes stator seat no longer cut stray field, eliminates the vortex flow in the stator seat, thereby improves generator efficiency, reduces operator's physical demands.
Specifically, a kind of high efficiency outer rotor shaft streaming microgenerator, this generator is made up of rotor and stator, and its rotor is made up of rotator seat, armature spindle, magnet and rotor bearing, and stator is made up of stator seat, iron core, stator line bag and stator bearing; Rotator seat is fixed on the armature spindle through interference fit, rotates with armature spindle; Magnet alternately is fixed on the rotator seat inner surface at interval according to " S " level and " N " level; Stator is fixed on the generator housing through stator seat, and the stator line surrounds on the iron core and is fixed on together on the stator seat, it is characterized in that being provided with the device that the shielding stray field is eliminated vortex flow in the stator seat at the magnet end face.
The utility model beneficial effect: the scheme that utilization the utility model provides, thoroughly eliminated the leakage field beyond the rotor end-face, stator seat no longer cuts stray field, no longer forms vortex flow.So, generator no longer because of the vortex flow heating, has improved generator efficiency and life-span, has reduced operator's physical demands.

Embodiment
A kind of high efficiency outer rotor shaft streaming microgenerator, this generator is made up of rotor and stator, and its rotor is made up of rotator seat 1, armature spindle 2, magnet 3 and rotor bearing 4, and stator is made up of stator seat 5, iron core 6, stator line bag 7 and stator bearing 8; Rotator seat 1 is fixed on the armature spindle 2 through interference fit and rotates with armature spindle 2, and magnet 3 alternately is pasted and fixed on rotator seat 1 inner surface at interval according to " S " level and " N " level; Stator is fixed on the generator housing through stator seat 5, and stator line bag 7 also is fixed on the stator seat 5 on iron core 6 together, it is characterized in that being provided with the device that the shielding stray field is eliminated vortex flow in the stator seat at magnet 3 end faces.
As shown in Figure 6, described stray field shield is the becket 9 of the magnet 3 end faces magnetic conduction of adding a cover.Becket 9 is fit to the metal magnetism-isolating loop of rotor for an interior external diameter that adopts silicon steel sheet or other permeability magnetic material stamping-out, and relies on magnet magnetic force that magnetism-isolating loop is adsorbed on the rotor magnet end face.The electric generator structure that constitutes is as shown in Figure 7.
As shown in Figure 8, described stray field shield is the convex edge 10 that is positioned on the rotator seat 1.The electric generator structure that constitutes is as shown in Figure 9.
Find through analyzing; Magnet alternately sticks on the rotator seat inner surface by a determining deviation according to " S " level and " N " level; As long as add a cover the becket of a magnetic conduction to rotor inner magnet end face; Just can the magnetic line of force be got back in the magnet leakage field short circuit through becket, eliminate the stray field beyond the rotor end-face.According to generator and electrical material characteristics, this magnetism-isolating loop material is preferably selected the silicon steel sheet consistent with iron core for use, and is best at a distance from the magnetic effect.Through many experiments contrast, adopt magnetism-isolating loop after the generator leakage field eliminate basically, generator efficiency and life-span obviously improve, the people shakes or pin when stepping on, and has saved muscle power.
In like manner, as shown in Figure 8, if rotator seat is processed into the structure of band convex edge, press Fig. 9, though pasting difficulty, strengthens magnet, though effect does not have magnetism-isolating loop effective, the effect of shielding stray field also can be played in convex edge 10.Based on above advantage, special application is adopted magnetism-isolating loop and convex edge rotor structure with this kind, and shielding stray field, the method for raising generator efficiency are stepped on electrical generator fields and granted asylum relating to the hand or pin of dual-use manpower.
