The difference between ERM vibration motor and LRA vibration motor

Gabatarwa

Micro vibration Motorstaka muhimmiyar rawa a aikace-aikace iri-iri tun daga na'urorin lantarki zuwa na'urorin likitanci. Suna ba da damar amsawar haptic, sanarwar ƙararrawa, da faɗakarwar tushen jijjiga don haɓaka ƙwarewar mai amfani. Daga cikin nau'ikan nau'ikan injunan girgizar ƙasa a kasuwa, bambance-bambancen guda biyu na yau da kullun suneERM (eccentric rotating mass) injin girgizada kuma LRA (madaidaicin resonant actuator) injin girgiza. Wannan labarin yana da nufin fayyace bambance-bambance tsakanin ERM da Motocin rawar girgiza LRA, suna bayyana tsarin injin su, aiki da aikace-aikace.

Koyi game da injin girgiza girgizar ERM

ERM vibration Motorsana amfani da su sosai saboda sauƙin su, ƙimar farashi da dacewa mai faɗi. Waɗannan injina sun ƙunshi babban taro mai jujjuyawa akan mashin motar. Lokacin da taro ke juyawa, yana haifar da ƙarfi mara daidaituwa, wanda ke haifar da girgiza. Za'a iya daidaita girman girma da mitar girgiza ta hanyar sarrafa saurin juyawa. Motocin ERM an ƙera su don samar da girgizar ƙasa akan kewayon mitar mai faɗi, yana sa su dace da sanarwa mai taushi da ƙarfi.

Koyi game da injunan girgiza LRA

LRA vibration Motors, a gefe guda, yi amfani da wata hanya ta daban don haifar da jijjiga. Sun ƙunshi taro da aka haɗa da maɓuɓɓugar ruwa, suna samar da tsarin resonant. Lokacin da aka yi amfani da siginar lantarki, murɗaɗɗen motar yana haifar da taro don juyawa baya da gaba a cikin bazara. Wannan oscillation yana haifar da rawar jiki a mitar resonant na motar. Ba kamar injinan ERM ba, LRAs suna nuna motsin linzamin kwamfuta, wanda ke haifar da ƙarancin wutar lantarki da ingantaccen ƙarfin kuzari.

1. inganci da daidaito:

Motocin ERM yawanci suna cin ƙarin ƙarfi idan aka kwatanta da LRAs saboda motsin su na juyawa. LRA yana motsa shi ta hanyar oscillation na layi, wanda ya fi dacewa kuma yana cinye ƙarancin ƙarfi yayin isar da madaidaicin girgiza.

2. Sarrafa da sassauci:

Motocin ERM sun yi fice wajen isar da faffadan girgiza saboda yawan jujjuyawar su. Suna da sauƙin sarrafawa kuma suna ba da damar yin amfani da mitar da girma.Motar layi na al'adayana da motsi na layi wanda ke ba da iko mafi kyau, amma a cikin takamaiman kewayon mitar.

3. Lokacin amsawa da karko:

Motocin ERM suna nuna lokutan amsawa cikin sauri saboda suna isar da girgiza kai tsaye lokacin kunnawa. Koyaya, saboda tsarin jujjuyawar, suna da saurin lalacewa yayin amfani na dogon lokaci. LRA tana da tsarin murɗawa wanda ke daɗe kuma ya fi ɗorewa don aikace-aikacen da ke buƙatar tsawaita amfani.

4. Halayen surutu da girgiza:

Motoci na ERM sukan haifar da ƙarin hayaniya da watsa girgiza zuwa yanayin da ke kewaye. Sabanin haka, LRA yana samar da firgita mai santsi tare da ƙaramar amo, yana mai da shi dacewa da aikace-aikacen da ke buƙatar ra'ayi mai hankali.
