Yazi Okungakumbi NgeeMoto zeLRA Linear Vibration
1.Imbali ye-LRA (i-actuator ye-resonant ethe ngqo)
Ukusetyenziswa kwee-ERM vibration motors kwizixhobo zomntu siqu kwaqalwa yiMotorola ngo-1984. Ii-BPR-2000 kunye nee-OPTRX pagers zaziphakathi kwezixhobo zokuqala ukufaka olu phawu, zibonelela ngezaziso zomnxeba ongathethiyo kunye nempendulo yokungcangcazela encinci kumsebenzisi. Namhlanje, ii-LRA (ezaziwa ngokuba zii-linear actuators) zibonelela ngokuthembeka okuphezulu ngobukhulu obuncinci. Zisetyenziswa kakhulu kwizicelo zempendulo ye-haptic kunye nemisebenzi ye-alamu yokungcangcazela esisiseko. Ii-linear vibration motors zisetyenziswa kakhulu kwiifowuni eziphathwayo, ii-smartphones, izixhobo ezinxitywayo kunye nezinye izixhobo ezincinci ezifuna imisebenzi yokungcangcazela.
2. Umqhubi we-IC
I-Leader micro linear motor LD0832 kunye ne-LD0825 kufuneka zisetyenziswe ne-driver IC efana ne-TI DRV2604L okanye i-DRV2605L. I-TI (Texas Instruments) ithengisa ibhodi yovavanyo enale chip ye-IC kuyo. Jonga ikhonkco: https://www.ti.com/lsds/ti/motor-drivers/motor-haptic-driver-products.page
Ukuba ufuna i-IC engabizi kakhulu, singakucebisa ababoneleli baseTshayina abanomsebenzi ofanayo kodwa ngexabiso eliphantsi.
3. I-LRA Njengecandelo leSekethe
Xa iimoto ze-LRA zidityaniswe kwisekethe, zihlala zilula ngaphaya kwesekethe yazo efanayo, ngakumbi xa ziqhutywa yitshiphu yomqhubi we-LRA ezinikeleyo efana ne-DRV2603. Ngokudibanisa i-LRA kwiiphini ezifanelekileyo ze-IC ezizimeleyo, abayili kunye neenjineli banokonga ixesha kwaye bagxile kwezinye iinkalo zenkqubo.
Nangona i-back EMF ikhiqizwa yi-LRAs, abaqhubi abaninzi be-LRA basebenzisa esi siphumo njengendlela yokuva. Abanye abaqhubi be-IC balinganisa i-back EMF. Basebenzisa olu lwazi ukulungisa imvamisa yesiginali yokuqhuba ukuze bafumane i-resonance. Ivumela imveliso ukuba isebenze ngaphakathi kwemida kunye namanqanaba asondeleyo kungakhathaliseki iimeko okanye ubudala.
Kubalulekile ukuqaphela ukuba iimoto ze-LRA azinazo iibrashi. Azinazo iingxaki zokukhutshwa kwe-electromagnetic okunxulunyaniswa nokuxinana kwe-commutator kwiimoto ze-DC ERM. Olu phawu, olufana neemoto ze-ERM ezingenazo iibrashi, ngokubanzi lwenza ii-LRA zifaneleke kwizixhobo eziqinisekisiweyo ze-ATEX.
4.Ukuqhuba ii-Actuators ze-Linear Resonant / ii-Vibrators ze-Linear
Ii-vibrators ze-LRA ezithe nkqo zifuna isignali ye-AC ukuze zisebenze, njengeesithethi. Kungcono ukusebenzisa isignali ye-sine wave kwi-frequency ye-resonant, njengoko kubonisiwe kumfanekiso ongezantsi.
Kakade ke, ubukhulu be-drive waveform bunokuguqulwa ukuze kuveliswe iziphumo zempendulo eziphucukileyo.
5. Ubomi Obandisiweyo Bee-Vibrators Ezinemigca
Iimoto zokungcangcazela ze-LRA zahlukile kwiimoto ezininzi zokungcangcazela kuba zisebenzisa i-voice coil ukuqhuba ubunzima, nto leyo eyenza ukuba zingabi nabhrashi ngokufanelekileyo.
Olu yilo lunciphisa amathuba okuba intwasahlobo ingasebenzi kakuhle, eqhutywa kusetyenziswa uhlalutyo lwezinto ezilinganiselweyo (FEA) kwaye isebenza kwindawo engadinwayo. Ngenxa yokuba ukuguguleka koomatshini kuncinci kwaye indlela ephambili yokungasebenzi kakuhle inqunyelwe ekwaluphaleni kwezinto zangaphakathi, ixesha eliphakathi lokungasebenzi kakuhle (MTTF) lide kakhulu xa lithelekiswa neemoto zokungcangcazela ze-eccentric rotating mass (ERM) eziqhelekileyo.
