Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is to this hair
Bright explanation and the invention is not limited to following embodiments.
Referring to Fig. 1-6, miniature pneumatics generator in the present embodiment, by motor body 1, axle sleeve 2, output line 3 and 4 groups of blade
At, output line 3 is connect with motor body 1, and motor body 1 includes motor casing 5, be mounted on motor shaft 11 in motor casing 5, bracket 15,
Coil 14, magnetosheath 13 and rear cover 16, blade 4 pass through 11 one end of motor shaft and are mounted on axle sleeve 2,11 other end of motor shaft and branch
Frame 15 connects, and coil 14 is mounted on bracket 15, and magnetosheath 13 passes through nested axis 17 and connect with motor body 1, nested 17 inside two of axis
Two bearing shells 12 of end insertion, motor shaft 11 pass through two bearing shells 12 and install, and gap is equipped between motor shaft 11 and two bearing shells 12
And polishing treatment is made to reduce coefficient of friction in surface, rear cover 16 is mounted on 15 side of bracket.Using blade 4 as driving element,
When blade 4 is completed power generation around the rotation output electric current of magnetosheath 13 with moving winding 14 by motor shaft 11 by wind drive rotation.
The present invention can not only generate electricity and have the function of missile velocity sensor, only can just open after missile velocity reaches certain value
4 rotary electrification of movable vane piece, thus can automatic adaptation environment starting power generation, breach conventional power source need separately with control circuit
The problem of can control power supply output.
The present embodiment motor casing 5 uses stainless steel punching press one-pass molding, can be effective against external impacts, and axle sleeve 2 uses
