Nov yog Txoj Kev Sai Sai kom Paub txog Lub Cev Muaj Zog Vibration ntawm DC Motor.

Cov Tsav Tsheb Npib Vibration (nrog txhuam):

Iblub cev muaj zog of lub cev muaj zog coin vibrationtej zaum yuav siv tau rau hauv cov ntawv thov xws li cov moos ntse, cov cuab yeej taug qab kev noj qab haus huv thiab lwm yam khoom siv hnav tau. Lawv feem ntau siv los muab cov lus ceeb toom rau tus neeg siv, cov tswb ceeb toom lossis cov lus teb haptic. Cov motors hom "txhuam" feem ntau yog siv rau cov khoom lag luam qib neeg siv khoom qhov twg qhov kev co tsis yog qhov tseem ceeb ntawm cov khoom (lub voj voog ua haujlwm nruab nrab). Feem ntau ntawm cov khoom siv hom motor no. Txawm li cas los xij, yog tias koj daim ntawv thov xav tau lub sijhawm ntev heev ntawm lub cev muaj zog thiab MTBF siab xav txog kev siv pebBLDC Brushless Kev co Motors. Cov no kim dua li hom txhuam. Peb tuaj yeem muab peb lub cev muaj zog vibration nrog ntau yam o connectors, spring contacts, FPC lossis nrog cov ntaub qhwv tsis muaj dab tsi. Peb kuj tuaj yeem tsim ib qho FPC tshwj xeeb rau koj daim ntawv thov. Yog tias koj daim ntawv thov xav tau nws, cov ntaub qhwv ua npuas ncauj ntawm ntau qhov tuab thiab / lossis daim kab xev ob chav kuj tseem yuav raug ntxiv. Cov ntaub ntawv 3D CAD muaj thaum thov.

 

BLDC - Brushless DC Coin Vibration Motors:

BLDC Lub cev muaj zog dc tsis txhuamCov tshuab hluav taws xob co npib yog qhov kev xaiv zoo heev rau cov ntawv thov kev ntseeg siab uas xav tau lub neej ntev / MTBF. Cov ntawv thov uas qhov tshwj xeeb kev co siv ntau zaus lossis siv hauv cov khoom siv kho mob yuav tsum xav txog lub tshuab hluav taws xob BLDC. Cov tshuab hluav taws xob BLDC no feem ntau siv sijhawm ntev dua li lub neej ntawm cov tshuab hluav taws xob brushed hom ntau dua 10 npaug. Lawv kim dua li cov hom brushed vim lawv suav nrog tus tsav tsheb IC. Yuav tsum tau saib xyuas polarity thaum siv hluav taws xob. Lwm cov specs zoo ib yam li cov tshuab hluav taws xob brushed hom txheem.

 

Cov Tsav Tsheb Tawm Tsam (LRA):

Peb tsim ob qho tib si rectangular thiab npib hom LRA.
Vim lawv lub sijhawm nce thiab nqis sai thiab muaj peev xwm nres tau zoo dua,Cov linear resonant actuators (LRA) vibration motorsyog ib qho kev xaiv zoo heev rau cov ntawv thov haptic feedback. Lawv cov qauv sab hauv yooj yim kuj muab kev ntseeg siab siab thiab lub neej ntev heev thaum piv nrog cov brushed ERM motors. Cov thawj cojmini linear vibrating motomuaj ib qho loj sab hauv uas oscillates rov qab thiab tawm raws X-axis ntawm nws qhov zaus resonant. Peb cov npib zoo li tus linear resonant actuators oscillate raws Z axis, perpendicular rau lub cev muaj zog nto. Qhov Z axis vibration no xa cov kev co zoo hauv cov ntawv thov hnav. Hauv Hi-Rel daim ntawv thov, lawv yog lwm txoj hauv kev rau brushless vibration motors vim tias tsuas yog cov khoom sab hauv uas raug hnav / ua tsis tiav yog cov springs.

Hom Kev Teeb tsa 1: RECTANGULAR / BAR TYPE LRA nrog Cov Hlau Txuas

Hom Kev Teeb tsa 2: NPIB HOM LRA nrog Cov Hlau Txuas

Hom Kev Teeb tsa 3: Hom npib LRA nrog FPC

Tsis zoo li cov tshuab hluav taws xob brushed DC vibration motors ib txwm muaj, cov linear resonant actuators yuav tsum tau tsav los ntawm lub teeb liab AC ntawm cov khoom siv resonant zaus. Muaj ntau lub tuam txhab tsim IC drivers rau cov tshuab hluav taws xob linear vibration motors uas muab cov teeb liab tsav tsheb kom raug thiab muaj cov tsev qiv ntawv ntawm cov teebmeem haptic uas koj tuaj yeem xaiv los ntawm.

Yuav tsum nco ntsoov tias tsis zoo li cov tshuab hluav taws xob brushed ERM vibration, kev hloov pauv qhov amplitude ntawm qhov voltage siv tsuas yog yuav hloov qhov amplitude ntawm lub zog co, tsis yog qhov zaus ntawm kev co. Vim yog LRA's Hi-Q, kev siv zaus siab dua lossis qis dua qhov zaus resonant ntawm LRA yuav ua rau LRA tsim qhov amplitude qis dua lossis yog tias deb ntawm qhov zaus resonant, tsis muaj hlo li.
