Described BYJ motor electrically connects with motor driver, and described motor driver includes actuator housing and is arranged at institute
State the pcb board in drive shell body；It is provided with component on described pcb board,
Motor driver also include dust cleaning system, dust cleaning system include first dust stratification detection device, second amass
Ash detection device and dust blow device, dust blow device includes being swept into device of air 11, in the present embodiment, cleans air inlet dress
Putting to be supply fan or inlet air compressor, is swept at the air inlet of device of air 11 and arranges filter 12, cleans
Inlet duct 11 connects with the cleaning pipeline 13 of the component 19 installed surface side being arranged at pcb board 2, cleans on pipeline 13 also
It is arranged over multiple self adaptation gas outlet 14 at multiple components 19, the double gold of multi-disc is set at each self adaptation gas outlet 14
Belonging to piece 15, self adaptation is given vent to anger by the bimetal leaf 15 at each self adaptation gas outlet 14 when bimetal leaf 15 is in compared with cold state
Mouth 14 is closed, and when bimetal leaf 15 is in compared with Warm status to the bending of self adaptation gas outlet 14 lateral direction, gives vent to anger self adaptation
Mouth 14 is opened, and when the temperature of bimetal leaf 15 is higher, the amplitude that self adaptation gas outlet 14 is opened is bigger；
First dust stratification detection device includes the first capacitometer for measuring cell fin, and element radiating piece is by many
Individual fin monomer 16 is constituted, electric insulation between multiple fin monomers 16, the first capacitometer be connected with comparator and to
Comparator feedback actual measurement capacitance, comparator is also connected with memory, Memory Reference capacitance in memory, and reference capacitance value is
The capacitance between multiple fin monomers 16 when element radiating piece non-accumulation dust, when actual measurement capacitance is beyond with benchmark electricity
During the threshold value that capacitance is as the criterion and sets, be swept into device of air 11 and start, through filtered air via clean on pipeline 13 from
Adapt to gas outlet 14 to blow out, component 19 cleaned, dirty air through exhaust outlet 20 in actuator housing 11
Discharge.
Second dust stratification detection device light-beam generator and the meta of at least one component 19 being arranged on pcb board 2
The mirror surface 17 put, it is internal that light-beam generator is arranged on actuator housing 1, light-beam generator with fixing angle by line light
Bundle is transmitted into mirror surface 17, and after being reflected minute surface 17 reflection, light beam is projected onto be provided with within actuator housing 1 photosensitive
On switch 18, when photosensitive switch 18 senses less than reflection light, automatically start and be swept into device of air 11.
It owing to self adaptation gas outlet 14 being closed when bimetal leaf 15 is in compared with cold state, is in relatively at bimetal leaf 15
To the bending of self adaptation gas outlet 14 lateral direction during Warm status, self adaptation gas outlet 14 is opened, and when the temperature of bimetal leaf 15
When spending higher, the amplitude that self adaptation gas outlet 14 is opened is bigger；So that each self adaptation gas outlet 14
The temperature of element below self adaptation gas outlet 14 for the area is different and different.Because for the higher element of temperature, it dissipates
Hot side is long-pending can be designed to bigger, or the surface of radiator portion is more conducive to the exchange of heat, but exactly more beneficially heat
The structure of exchange is also to cause air flowing change more acutely or to make air pass through thinner gap, and this structure is just more
Being conducive to generation and the increase of dust stratification, the dust being accumulated after the identical time is more, just uses more empty when cleaning
Throughput is cleared up.
When fin accumulation dust is more, the gap between fin can reduce, and fin is as an entirety
Electric capacity can diminish, so when electric capacity is varied down to certain value, may mean that dust has run up to certain stage, institute
Clear up dust with needs.
When pcb board 2 and component 19 dust stratification are more, the dust stratification on mirror surface 17 is also more, when dust stratification relatively
When many, dust can produce obvious diffusing reflection effect, weakens the mirror-reflection effect of mirror surface 17 greatly, can lead
Cause photosensitive switch 18 and cannot receive the light intensity of sufficient intensity to be triggered.Also achieved for element by another mode
The automatic monitoring of superficial dust degree, thus significantly improve that element surface dust stratification is more and the short circuit that causes or heat radiation
The element burnout problems freely not caused.
By arranging capacitance detecting and light detection two ways, can backup each other, to guarantee when dust runs up to necessarily
When stage dust cleaning system can system in time, remove the dust of element surface covering.
Particularly, light-beam generator is laser generator 24.
Laser generator 24 directionality is good, and the light after mirror-reflection will not occur significantly to dissipate, but works as
After some surface attachment dust, after particularly dust accumulation is more, it will obvious diffusing reflection occurs.Thus improve
When having dust and a free from dust or when dust is many and dust is few, the discrimination of the light intensity that photosensitive switch 18 is able to receive that,
Improve the reliability for light-intensity test, reduce the possibility of error starting.
Particularly, fin monomer 16 is arranged on an insulating thermal conductor 23, edge between each fin monomer 16
The bearing of trend segmentation of diffusion sheet.
Insulating thermal conductor 23 can be attachment insulating barrier on metal material, in the case of significantly reducing heat conductivility,
Make each fin monomer 16 mutually insulated, so that constituting electric capacity between each monomer of fin.By making each
Fin is split along bearing of trend, can independently constitute electric capacity, it is simple to wiring between each fin monomer 16.
Particularly, the quantity of the bimetal leaf 15 at each 14, self adaptation gas outlet is 6.Bimetal leaf 15 includes
Active layers and passive layer, active layers is manganin manganin alloy, and the material of passive layer is mainly dilval.
When the quantity of bimetal leaf 15 is 6, the lateral restriction tension force in each bimetal leaf 15 is less,
So that bimetal leaf 15 forms bigger flexural deformation, the quantity of sheet metal is enough, it is not necessary to be further added by sheet metal
Quantity to reduce the reliability of system.
Bimetal leaf 15 uses monel as active layers, and its deformation quantity is relatively big, thus obtains obvious opening
Effect.
Particularly, 0.9 times of capacitance on the basis of the lower limit of threshold value.
On the basis of capacitance when 0.9 times of capacitance, the dust on electric elements is more, if not in time
Cleaning, it will cause element radiating not smooth, thus reduce the serviceability of detection device.
It is as follows that the dust of the present embodiment cleans operating principle:
When between component or fin, upper dust stratification is more, the actual range between fin monomer can under
Fall, the air of the non-conductor as electricity between metal fin, also have the space shared by partial air and taken by dust
In generation, so the electric capacity between fin monomer can decline step by step with the accumulation of dust.When capacitance is low under threshold value
In limited time, startup is swept into device of air.
It in addition to this detection mode, is also provided with the mode of light detection, when dust accumulates relatively on mirror surface
When many, the albedo of mirror-reflection can be reduced, reduce the intensity of illumination that photosensitive switch can receive, photosensitive switch sense
Should be less than reflection light, then photosensitive switch Guan Bi, automatically start and be swept into device of air.
It is swept into after device of air starts and absorbs filtered cleaned air from the external world, send into and clean in pipeline.Due to
Bimetal leaf at self adaptation gas outlet is as temperature to be changed and shape is altered in steps, so self adaptation gas outlet now
Open, and, the self adaptation gas outlet above hotter element is opened bigger, above slightly colder element
Self adaptation gas outlet is opened less, so that the flow of cleaned air can different the dividing according to the different temperatures of element
Cloth, to improve the utilization ratio of cleaned air.Can allow be swept into after device of air first blows the very first time and be automatically switched off, such as first
Time can be half a minute.Then waited for the second time allowed and be suspended in the ash fall of actuator housing inner space, though because
The dust of component surface is blown afloat by right giving vent to anger of self adaptation gas outlet, and constantly supplements to actuator housing inner space
Air, says from main trend, and the air being mixed with dust can be discharged from exhaust outlet, but cannot guarantee that after some time, mixed
The air having dust will all be discharged from actuator housing inner space.So after blowing over a period of time, actuator housing
The air in interior space, is still the air being mixed with a small amount of dust in fact, so needing to wait for a period of time, allows dust in air sink
Fall.Such as second time can be 3 minutes or 2 minutes.After ash fall in drive shell body, then detect electric capacity, if
Remain less than threshold value, then continue to clean, if the need arises then so repeatedly, so that the ash on element and circuit board
Dirt is cleaned up.
