The difference between ERM vibration motor and LRA vibration motor

Introduce

Micro vibration motakuita basa rakakosha mumhando dzakasiyana dzemashandisirwo kubva kumagetsi evatengi kusvika kumidziyo yekurapa. Ivo vanogonesa haptic mhinduro, alarm zviziviso, uye vibration-yakavakirwa chenjedzo kuti uwedzere ruzivo rwemushandisi. Pakati pemhando dzakasiyana dze micro vibration motors pamusika, iwo maviri anowanzo siyana akasiyanaERM (eccentric inotenderera misa) vibration motauye LRA (mutsara resonant actuator) vibration motors. Ichi chinyorwa chine chinangwa chekujekesa mutsauko uripo pakati peERM neLRA vibration motors, kujekesa chimiro chavo chemuchina, kuita uye mashandisiro.

Dzidza nezve ERM vibration mota

ERM vibration motaanoshandiswa zvakanyanya nekuda kwekureruka kwavo, kudhura-kushanda uye kuenderana kwakakura. Aya mota ane eccentric mass inotenderera pane mota shaft. Kana huwandu huchitenderera, hunogadzira simba risina kuenzana, rinokonzera kuzununguka. Iyo amplitude uye frequency ye vibration inogona kugadziridzwa nekudzora kumhanya kutenderera. ERM mota dzakagadzirirwa kuburitsa vibrations pamusoro pehupamhi frequency renji, ichiita kuti ive yakakodzera kune zvese zvinyoro uye zvakanyanya zviziviso.

Dzidza nezve LRA vibration motors

LRA vibration mota, kune rumwe rutivi, shandisa imwe nzira kugadzira vibration. Izvo zvinosanganisira misa yakabatana nechitubu, ichigadzira resonant system. Kana chiratidzo chemagetsi chikaiswa, coil yemota inoita kuti misa itenderere kumashure nekudzoka mukati mechirimo. Iyi oscillation inoburitsa vibration pane resonant frequency yemota. Kusiyana neERM motors, LRAs inoratidzira mutsara kufamba, zvichikonzera kuderera kwesimba rekushandisa uye yakanyanya simba kushanda nesimba.

Kuenzanisa Kuongorora

1. Kushanda uye kurongeka:

ERM mota dzinowanzoshandisa simba rakawanda zvichienzaniswa neLRAs nekuda kwekufamba kwavo. Iyo LRA inotyairwa nemutsara oscillation, iyo inoshanda zvakanyanya uye inoshandisa simba shoma uku ichiburitsa chaiyo vibrations.

2. Kudzora uye Kuchinjika:

ERM mota dzinoita zvakanaka pakuunza huwandu hwakakura hwemavibrations nekuda kwekutenderera kwawo eccentric mass. Iwo ari nyore kudzora uye anobvumira kushandura frequency uye amplitude.Tsika mutsara motaine mutsara inofamba inopa kutonga kwakanaka, asi mukati meiyo frequency renji.

3. Nguva yekupindura uye kusimba:

ERM mota dzinoratidza nguva dzekupindura dzinokurumidza nekuti dzinoburitsa vibration ipapo painovhurwa. Nekudaro, nekuda kweiyo inotenderera nzira, ivo vanowanzo pfeka uye kubvarura panguva yekushandiswa kwenguva refu. Iyo LRA ine oscillating michina inotora nguva yakareba uye yakasimba kune maapplication anoda kushandiswa kwenguva refu.

4.Noise uye vibration maitiro:

ERM mota dzinowanzo kuburitsa ruzha uye kufambisa vibrations kune yakatenderedza nharaunda. Kusiyana neizvi, LRA inogadzira mavibrations akapfava ane ruzha rushoma, ichiita kuti ive yakakodzera kune maapplication anoda yakangwara tactile mhinduro.

Nzvimbo dzekushandisa

ERMmadiki anozunguza motaanowanzo kuwanikwa munharembozha, zvinopfekwa, uye zvinodzora zvemitambo zvinoda kuwanda kwekudedera. MaLRA, kune rumwe rutivi, anowanzo shandiswa mumidziyo yekurapa, zvikirini zvekubata, uye zvinopfekwa zvinoda kudengenyeka uye kusinganzwisisike.

Mukupedzisa

Muchidimbu, sarudzo yeERM uye LRA vibration motorszvinoenderana nezvinodiwa zvekushandisa. ERM mota dzinopa yakafararira vibration renji pamutengo wekushandisa kwesimba, nepo LRAs ichipa yakanyatso kudengenyeka uye yakakura kushanda nesimba. Kunzwisisa misiyano iyi kunogona kubatsira vagadziri, mainjiniya, uye vanogadzira kuita sarudzo dzine ruzivo pakusarudza ma micro vibration motors kune avo maapplication. Pakupedzisira, sarudzo pakati peERM neLRA motors inofanira kunge yakavakirwa pazvinhu zvakaita sesimba rekushandisa, kutonga kuchinjika, kudiwa kwechokwadi, kusimba, uye kufunga ruzha.
