Pamene ma mota a LRA aphatikizidwa mu dera, nthawi zambiri amakhala osavuta kupitirira dera lawo lofanana, makamaka akamayendetsedwa ndi chip choyendetsera cha LRA monga DRV2603. Mwa kulumikiza LRA ku mapini oyenera a IC yokha, opanga ndi mainjiniya amatha kusunga nthawi ndikuyang'ana kwambiri mbali zina za dongosololi.
Ngakhale kuti ma LRA amapanga back EMF ndi ma driver ambiri a LRA, ma driver ambiri a LRA amagwiritsa ntchito izi ngati njira yodziwira. Ma driver ena a IC amayesa back EMF. Amagwiritsa ntchito izi kusintha ma frequency a drive signal kuti apeze resonance. Zimathandiza kuti chinthucho chigwire ntchito mkati mwa malire ndi milingo yoyandikana mosasamala kanthu za mikhalidwe kapena zaka.
Ndikofunikira kudziwa kuti ma mota a LRA sagwiritsa ntchito burashi. Savutika ndi mpweya woipa wa ma elekitiroma womwe umakhudzana ndi kugwedezeka kwa ma commutator mu ma mota a DC ERM. Khalidweli, lofanana ndi ma mota a ERM opanda burashi, nthawi zambiri limapangitsa ma LRA kukhala oyenera zida zovomerezeka za ATEX.
4.Kuyendetsa Ma Linear Resonant Actuators / Linear Vibrators
Ma vibrators a LRA linear amafuna chizindikiro cha AC kuti agwire ntchito, mofanana ndi ma speaker. Ndi bwino kugwiritsa ntchito chizindikiro cha sine wave pa resonant frequency, monga momwe chithunzi chili pansipa chikusonyezera.
Zachidziwikire, kukula kwa mawonekedwe a mafunde a drive kumatha kusinthidwa kuti apange zotsatira zapamwamba kwambiri zokhuza kukhudza.
5. Moyo Wonse Wowonjezera wa Ma Vibrators Olunjika
Ma mota ogwedera a LRA amasiyana ndi ma mota ambiri ogwedera chifukwa amagwiritsa ntchito cholumikizira mawu poyendetsa unyinji, zomwe zimapangitsa kuti asakhale ndi burashi.
Kapangidwe kameneka kamachepetsa kuthekera kwa kulephera kwa masika, komwe kumapangidwa pogwiritsa ntchito finite element analysis (FEA) ndipo kumagwira ntchito m'malo osatopa. Chifukwa chakuti kuwonongeka kwa makina kumakhala kochepa ndipo njira yayikulu yolephera imangokhala yokalamba kwa zigawo zamkati, nthawi yapakati yolephera (MTTF) ndi yayitali kwambiri poyerekeza ndi ma motors ozungulira ozungulira (ERM) ozungulira.
Funsani Opanga Magalimoto Anu a Leader Linear
Timakuthandizani kupewa mavuto kuti mupereke khalidwe labwino komanso kufunika kwa injini zanu zazing'ono za LRA, panthawi yake komanso pa bajeti.
