Vibration Motors: Eccentric Rotathauv pawg (ERM) Thiab Linear Resonant Actuators (LRA)
LEADER Micro Motor txaus siab muab ntau yam ntawm DC vibration motors, nrog rau cov qauv muaj nyob rau txhua lub sijhawm. Featuring ntau yam thev naus laus zis thiab qhov ntau thiab tsawg dua Ø12 hli, peb cov motors muaj npe nrov rau lawv cov khoom siv tes ua haujlwm zoo thiab pheej yig. Tsis tas li ntawd, peb muab cov kev xaiv customizable heev kom tau raws li cov kev cai tshwj xeeb ntawm cov ntawv thov sib txawv.
Kev vibration motortshuab
Peb pab pawg engineers tshwj xeeb hauv kev tsim kev vibration thiab tactile tawm tswv yim daws teeb meem siv plaub lub zog tshwj xeeb thev naus laus zis. Txhua lub tshuab muaj nws tus yam ntxwv, qhov zoo thiab kev lag luam tawm. Los ntawm kev nkag siab txog qhov tshwj xeeb zoo thiab kev cuam tshuam ntawm txhua lub tshuab, peb muaj peev xwm tsim cov kev daws teeb meem kom tau raws li cov kev cai tshwj xeeb ntawm peb cov neeg siv khoom.
Eccentric Rotathauv Mass (ERM) Vibration Motors
ERM motors yog thawj thev naus laus zis los tsim kev vibrations thiab muab ntau yam zoo. Lawv yog cov neeg siv-phooj ywg, tuaj nyob rau hauv ntau qhov ntau thiab tsawg, thiab tuaj yeem hloov kho tau yooj yim hauv kev vibration amplitude thiab zaus kom haum rau txhua daim ntawv thov.
Cov nonpib hom vibration motortuaj yeem pom nyob rau hauv ntau yam khoom siv, los ntawm me me smart watches mus rau lub kauj tsheb loj. Ntawm peb lub tuam txhab, peb tshwj xeeb hauv kev tsim thiab tsim kev vibration motors nrog cov tshuab sib txawv xws li cov tub ntxhais hlau, coreless thiab brushless. Cov motors no muaj nyob rau hauv cylindrical thiab npib hom ntawv.
Ib qho ntawm qhov zoo ntawm ERM motors yog lawv qhov yooj yim thiab yooj yim ntawm kev siv.
DC motors, tshwj xeeb, yog ib qho yooj yim los tswj, thiab yog tias lub neej ntev yog qhov tseem ceeb,8 hli tiaj npib vibration lub cev muaj zogsiv tau.
Txawm li cas los xij, muaj qee qhov kev cuam tshuam los xav txog. Muaj kev sib raug zoo geometric ntawm kev vibration amplitude thiab zaus thiab ceev, uas txhais tau hais tias nws tsis tuaj yeem kho amplitude thiab zaus ntawm nws tus kheej.
Yuav kom ua tau raws li qhov xav tau sib txawv, peb muab peb lub cev muaj zog thiab thev naus laus zis. Iron core motors muab kev xaiv tus nqi qis dua, coreless motors muaj qhov sib npaug ntawm tus nqi thiab kev ua haujlwm, thiab brushless motors muaj qhov ua tau zoo tshaj plaws thiab lub neej ntev tshaj plaws.
Linear Resonant Actuators (LRA)
Linear resonant actuators (LRA) ua haujlwm zoo li tus hais lus tshaj li lub cev muaj zog. Es tsis txhob cones, lawv muaj ib pawg uas txav rov qab los ntawm lub suab coil thiab lub caij nplooj ntoos hlav.
Ib qho tshwj xeeb ntawm LRA yog nws cov zaus resonant, thaum lub amplitude ncav cuag nws qhov siab tshaj plaws. Deviating txawm ob peb Hertz los ntawm qhov resonant zaus tuaj yeem ua rau poob loj hauv kev vibration amplitude thiab lub zog.
Vim muaj qhov sib txawv me ntsis, qhov zaus ntawm txhua LRA yuav txawv me ntsis. Yog li ntawd, tus tsav tsheb tshwj xeeb IC yuav tsum tau hloov kho lub teeb liab tsav thiab tso cai rau txhua tus LRA kom resonate ntawm nws tus kheej resonant zaus.
LRAs feem ntau pom muaj nyob rau hauv smartphones, me touchpads, tracker pads, thiab lwm yam khoom siv tes uas hnyav dua 200 grams. Lawv tuaj nyob rau hauv ob lub ntsiab duab - npib thiab tuav - raws li zoo raws li ib co square designs. Lub axis ntawm kev co yuav txawv nyob ntawm daim ntawv, tab sis nws ib txwm tshwm sim raws ib qho axis (tsis zoo li ERM lub cev muaj zog uas vibrates ntawm ob axes).
Peb cov khoom lag luam tau hloov pauv tas li kom tau raws li cov neeg siv khoom xav tau. Yog tias koj tab tom txiav txim siab siv LRA, nws yuav muaj txiaj ntsig los sab laj nrog ib qho ntawm peb cov kws tsim qauv tsim daim ntawv thov.
Hom kev vibration motor form factor
Txawm hais tias siv tshuab vibration motor, ntau yam qauv ntawm cov qauv tsim thiab kev txiav txim siab tsim muaj nyob rau hauv kev lag luam. Cov yam tseem ceeb no feem ntau yog tig los ntawm kev sib txuas hluav taws xob sib txuas. Nov yog qee cov lus piav qhia ntawm cov qauv zoo li no los pab koj txiav txim siab koj txoj kev daws teeb meem.
Peb yuav pab tau li cas
Txawm hais tias kev sib koom ua ke ntawm kev vibration lub cev muaj zog rau hauv koj daim ntawv thov yuav zoo li yooj yim, kev ua tiav kev tsim khoom loj tuaj yeem nyuaj dua li qhov xav tau.
Nws yog ib qho tseem ceeb kom xav txog ntau yam, suav nrog:
Vibration amplitude thiab zaus,
Lub cev muaj zog winding tuning ntawm lub zog mov,
Audible suab nrov,
Lub cev muaj zog,
Tactile teb cov yam ntxwv,
EMI / EMC hluav taws xob suab nrov,
...
Nrog peb cov khoom tsim thiab ntim ntau lawm, peb tuaj yeem saib xyuas qhov no kom koj tuaj yeem tsom mus rau kev txhim kho tus nqi ntxiv ntawm koj daim ntawv thov.
Tham nrog koj tus thawj coj kws tshaj lij
Peb pab koj kom tsis txhob muaj qhov cuam tshuam kom xa cov khoom zoo thiab muaj nuj nqis rau koj qhov kev xav tau micro brushless lub cev muaj zog, raws sijhawm thiab nyiaj txiag.
