Yazi Okwengeziwe Ngama-LRA Linear Vibration Motors
1. Umlando we-LRA (i-actuator ye-resonant eqondile)
Ukusetshenziswa kwama-motor okudlidliza e-ERM kumadivayisi kagesi omuntu siqu kwaqalwa yi-Motorola ngo-1984. Ama-pager e-BPR-2000 kanye ne-OPTRX ayephakathi kwamadivayisi okuqala ukufaka lesi sici, enikeza izexwayiso zokushaya ucingo oluthule kanye nempendulo yokudlidliza ehlanganisiwe kumsebenzisi. Namuhla, ama-LRA (aziwa nangokuthi ama-actuator aqondile) anikeza ukuthembeka okuphezulu ngobukhulu obuncane. Avame ukusetshenziswa ezinhlelweni zokusebenza zempendulo ye-haptic kanye nemisebenzi ye-alamu yokudlidliza eyisisekelo. Ama-motor okudlidliza aqondile asetshenziswa kabanzi kumaselula, ama-smartphone, amadivayisi agqokwayo nakwamanye amadivayisi amancane adinga imisebenzi yokudlidliza.
2. I-IC yomshayeli
I-leader micro linear motor LD0832 kanye ne-LD0825 kufanele isetshenziswe ne-driver IC efana ne-TI DRV2604L noma i-DRV2605L. I-TI (Texas Instruments) ithengisa ibhodi lokuhlola elinale chip ye-IC kuyo. Hlola isixhumanisi: https://www.ti.com/lsds/ti/motor-drivers/motor-haptic-driver-products.page
Uma ufuna i-IC engabizi kakhulu, singakuncoma abahlinzeki baseShayina abanekhono elifanayo kodwa ngentengo ephansi.
3. I-LRA Njengengxenye Yesekethe
Uma ama-motor e-LRA ehlanganiswa kwisekethe, avame ukuba lula ngale kwesekethe efanayo, ikakhulukazi uma eqhutshwa yi-chip yomshayeli we-LRA ezinikele njenge-DRV2603. Ngokuxhuma i-LRA kumaphini afanele e-IC ezimele, abaklami nonjiniyela bangonga isikhathi futhi bagxile kwezinye izici zesistimu.
Naphezu kokukhiqizwa kwe-back EMF ngama-LRA, abashayeli abaningi be-LRA basebenzisa lo mphumela njengendlela yokuzwa. Abanye abashayeli be-IC balinganisa i-back EMF. Basebenzisa lolu lwazi ukulungisa imvamisa yesiginali yokushayela ukuthola i-resonance. Kwenza umkhiqizo usebenze ngaphakathi kwemingcele eseduze namazinga kungakhathaliseki izimo noma ubudala.
Kubalulekile ukuqaphela ukuthi ama-motor e-LRA awanamabhulashi ngempumelelo. Awahlushwa ukukhishwa kwe-electromagnetic okuhambisana nokugoba kwe-commutator kuma-motor e-DC ERM. Lesi sici, esifana nama-motor e-ERM angenamabhulashi, ngokuvamile senza ama-LRA afanelekele imishini eqinisekisiwe ye-ATEX.
4. Ukushayela Ama-Actuator Aqondile Ane-Resonant / Ama-Vibrators Aqondile
Ama-vibrator e-LRA aqondile adinga isignali ye-AC ukuze asebenze, njengesikhulumi. Kungcono ukusebenzisa isignali ye-sine wave ngemvamisa ye-resonant, njengoba kuboniswe esithombeni esingezansi.
Vele, ubukhulu be-drive waveform bungashintshwa ukuze kukhiqizwe imiphumela yempendulo ethintayo ethuthukisiwe kakhulu.
5.Isikhathi Sokuphila Esinwetshiwe Sezivikeli Eziqondile
Ama-motor okudlidliza e-LRA ahlukile kuma-motor amaningi okudlidliza ngoba asebenzisa i-voice coil ukushayela i-mass, okwenza angabi namabhulashi ngempumelelo.
Lo mklamo unciphisa amathuba okwehluleka kwentwasahlobo, okwenziwa imodeli kusetshenziswa ukuhlaziywa kwe-finite element (FEA) futhi kusebenza endaweni engakhathali. Ngenxa yokuthi ukuguguleka komshini kuncane futhi imodi yokuhluleka eyinhloko inqunyelwe ekugugeni kwezingxenye zangaphakathi, isikhathi esimaphakathi sokwehluleka (MTTF) side kakhulu uma siqhathaniswa nama-vibration motors ajwayelekile axutshwe nge-eccentric rotating mass (ERM).
Xhumana Nabakhiqizi Bakho Bezimoto Ezihamba Ngomugqa Eziyinhloko
Sikusiza ukuthi ugweme izingibe zokuletha ikhwalithi nokwazisa izidingo zama-motor akho e-LRA amancane, ngesikhathi nangesabelomali.
