Kodi Njinga Yogwedezera Ndalama Imagwira Ntchito Bwanji?

Izi zazing'ono komanso zazing'onomakina ogwedera a ndalamaamapezeka kwambiri m'mafoni a m'manja, zida zotsatirira masewera olimbitsa thupi ndi zipangizo zina zamagetsi zonyamulika.

Ma mota athu ozungulira ndalama kapena ma pancake vibration amapangidwa ngati ma mota ozungulira ozungulira (ERM), kotero amatha kugwiritsidwa ntchito pogwiritsa ntchito njira zomwezo monga ma mota a pager. Amagwiritsa ntchito mfundo yofanana ya motor drive, kuphatikizapo kugwiritsa ntchito H-bridge circuit poyendetsa mabuleki.

Kapangidwe ka mota yogwedeza ndalama yopangidwa ndi brushed coin vibration motor kumaphatikizapo PCB yathyathyathya yomwe dera lozungulira la 3-pole limakonzedwa mozungulira shaft yamkati yomwe ili pakati. Rotor ya mota yogwedeza imakhala ndi "ma voice coil" awiri ndi chidutswa chaching'ono chophatikizidwa mu diski yathyathyathya yapulasitiki yokhala ndi bearing pakati, yomwe ili pa shaft. Maburashi awiri pansi pa diski yapulasitiki amakhudzana ndi ma PCB commutation pads ndikupereka mphamvu ku voice coil, ndikupanga mphamvu ya maginito. Mphamvu ya maginito iyi imagwirizana ndi mphamvu ya maginito yopangidwa ndi maginito ya disc yolumikizidwa ku chassis ya mota.

Dongosolo losinthira limasintha njira ya munda kudzera mu ma voice coil, ndipo izi zimagwirizana ndi ma NS pole pairs omwe amamangidwa mu neodymium magnet. Diski imazungulira ndipo, chifukwa cha kupangika kwa eccentric komwe sikuli pakati,motakunjenjemera!
