Buku Lotsogolera Magalimoto Opanda Brush: Magalimoto Ochepa a BLDC Opangira Mapangidwe Ochepa Malo

Dziwani momwe ma mota opanda burashi (ma mota owonda a BLDC) amathandizira mainjiniya kuthetsa zopinga za malo mu zida zamakono. Onani kapangidwe kake, kuphatikiza kwa FPCB, kugwiritsa ntchito, ndi malangizo osankha OEM.

Mfundo Zazikulu za Nkhaniyi

"Woonda" tsopano ndi wofunika kwambiri kuposa "wamng'ono" pakupanga zipangizo zamakono

Ma mota opanda burashi amachepetsa kutalika pogwiritsa ntchito kapangidwe kotsika ka L/D

Kulumikizana kwa FPCB kumatha kusunga malo okwana 0.5–1mm

Sikuti ntchito zonse zoonda zimafuna kapangidwe kapadera ka "mota yathyathyathya"

Ma mota ang'onoang'ono a BLDC (φ5–12mm) ndi opyapyala kwambiri nthawi zambiri.

Ntchito zazikulu zikuphatikizapo zinthu zovalidwa, zipangizo za TWS, ndi zida zachipatala zogwiritsidwa ntchito m'manja

Kapangidwe koyenera ka kutentha ndi kulumikizana ndikofunikira kwambiri kuposa mawonekedwe a injini

Kusankhidwa kwa OEM kuyenera kuyang'ana kwambiri pa kuphatikiza makina, osati kukula kwa magalimoto okha

Chiyambi: Chifukwa Chake "Woonda" Wakhala Vuto Latsopano Lopanga Kapangidwe

M'zaka zingapo zapitazi, chizolowezi chachikulu cha zamagetsi ndi zida zamankhwala sichilinso "chochepa" - koma chachepa.

Mahedifoni a TWS akuchepa kuchoka pa 12mm mpaka 8mm. Mawotchi anzeru ayenera kuphatikiza masensa ambiri m'mabotolo owonda kwambiri a 4–6mm. Zipangizo zachipatala zogwiritsidwa ntchito m'manja zikuchepa kwambiri pamene zikugwira ntchito bwino. Ngakhale zida zamafakitale tsopano zikulepheretsedwa ndi malire a kutalika.

Mu mapangidwe awa, mainjiniya sakufunsanso kuti "mota ingakhale yaying'ono bwanji?" koma m'malo mwake:

"Kodi tingaike bwanji injini pamalo ochepa kwambiri oimirira?"

Apa ndi pomwe ma mota opanda maburashi (ma mota owonda a BLDC) amakhala ofunikira.

Kodi Galimoto Yopanda Brush Yopanda Flat ndi Chiyani?

Mawu akuti "mota yopanda burashi" (kapena mota ya pancake BLDC) si okhazikika mumakampani. Opanga osiyanasiyana amatanthauzira mosiyana, koma muzochita zauinjiniya, nthawi zambiri amatanthauza mfundo ziwiri zazikulu:

1. Kapangidwe ka Flatness (Chiŵerengero Chotsika cha L/D)

Ma mota achikhalidwe ozungulira nthawi zambiri amakhala ndi chiŵerengero cha L/D (kutalika mpaka m'mimba mwake) choposa 1.

Ma mota athyathyathya amasinthira kapangidwe kake:

Chidutswa chake ndi chachikulu

Kutalika kwachepa kwambiri

Chiŵerengero cha L/D ndi chochepera 1

Mwachitsanzo, φ8 × 2.5mmLBM0825Mota ya micro BLDC ili ndi chiŵerengero cha L/D cha 0.31 — kale yosalala kwambiri malinga ndi miyezo ya makampani.

Izi zikusonyeza chidziwitso chofunikira:

Nthawi zambiri, simukusowa "mota yosalala" yapadera — ma mota wamba a BLDC amakhala opyapyala kwambiri.

2. Kulumikizana Kokhazikika (Kuphatikizana kwa FPCB)

Mu kapangidwe ka OEM yeniyeni, vuto lalikulu kwambiri la kutalika nthawi zambiri si mota yokha - koma mawaya.

Mawaya achikhalidwe a lead amafuna kupindika kwa 2–4mm. Malo owonjezerawa nthawi zambiri amakhala chifukwa chobisika chomwe chinthu sichingakwaniritse cholinga chake cha makulidwe.

Mabodi Ozungulira Osindikizidwa Osinthasintha (FPCB) amathetsa vutoli mwa:

Kuchotsa malo opindika waya

Kulola kulumikizana kwa PCB molunjika pansi

Kuchepetsa kutalika kwa chipangizo chonse ndi 0.5–1mm

Pakupanga chipangizo chopyapyala, kapangidwe ka kulumikizana n'kofunikira mofanana ndi kapangidwe ka injini.

Kugwiritsa Ntchito Kofunika Kwambiri kwa Thin BLDC Motors

Ma mota opanda burashi si njira zothetsera mavuto onse. Mtengo wawo umaonekera pokhapokha ngati kutalika kwake kwakhala koletsedwa kwambiri.

1. Ma TWS Earbuds ndi Ma Charging Cases (kutalika kwa ≤5mm)

Kutalika komwe kulipo: 3–5mm

Yankho lachizolowezi: φ5–6mm micro BLDC

Chitsanzo:LBM0525Mota ya φ5 × 2.5mm yokhala ndi cholumikizira cha pansi cha FPCB

Zofunikira zazikulu:

Kugwiritsa ntchito mphamvu zochepa kwambiri

Kugwedezeka kwa phokoso lochepa

Ndemanga yocheperako ya haptic

2. Mawotchi Anzeru ndi Zovala (kutalika kwa ≤4mm)

Kukhuthala kwamkati kochepa kwambiri

Kulumikizana kwa FPCB kumakhala kofunikira

Chosankha chofala: φ6mm BLDC yopyapyala kwambiri

Zofunikira zazikulu:

Mphamvu yochepa yoyimirira

Mphamvu yosinthika yogwedera

Kudalirika kwambiri m'malo oyenda

3. Zipangizo Zachipatala Zogwiritsidwa Ntchito M'manja (kutalika kwa 8–15mm)

Zoletsa malo apakati

Kukula kwa magalimoto wamba: φ8–12mm

Kuyang'ana bwino mphamvu ya kugwedezeka ndi kukhazikika

Zofunikira zazikulu:

Mphamvu yokhazikika yotulutsa mphamvu

Kudalirika kwa moyo wautali

Phokoso lochepa la mawu

4. Mapiritsi Oonda & Ma Panel Amakampani (kutalika kwa ≤8mm)

Kuyang'ana kwambiri kumasintha kuchokera pa kukula kupita ku kayendetsedwe ka kutentha

Ma mota opyapyala akuluakulu (φ10–12mm)

Yopangidwira kugwira ntchito mosalekeza

Zofunikira zazikulu:

Kutaya kwa kutentha kudzera m'nyumba zozungulira

Kulamulira kwa EMC

Kugwira ntchito kokhazikika kwa nthawi yayitali

Chifukwa Chake FPCB Ndi Yofunika Kwambiri Pakupanga Magalimoto Ochepa

Mu mapulojekiti ambiri a OEM, mainjiniya amangoyang'ana kwambiri kukula kwa injini. Komabe, muzochitika zenizeni zolumikizira, kapangidwe ka kulumikizana nthawi zambiri kamatsimikizira kupambana kapena kulephera.

FPCB imathetsa mavuto atatu akuluakulu a uinjiniya:

1. Kuchotsa Zinyalala Zochotsa Zoyima

Mawaya a lead amafuna malo opindika.

FPCB yachotsa izi kwathunthu, zomwe zathandiza kuti pakhale mgwirizano wolimba.

2. Zimathandiza Kuti Ntchito Yopanga Igwire Bwino Ntchito

Kusokera waya wachikhalidwe: masitepe angapo

Yankho la FPCB: sitepe imodzi yolumikizirana

Kupititsa patsogolo magwiridwe antchito mpaka 30%

3. Kumawonjezera Kudalirika kwa Makina

Mawaya owonda m'malo ogwedezeka nthawi zambiri amalephera chifukwa cha kutopa.

FPCB imagawa kupsinjika mofanana kwambiri ndipo imakulitsa kwambiri kulimba.

Kodi Galimoto Yokhala ndi Flat Motor Ndi Yofunika Nthawi Zonse?

Ayi — ndipo uku ndi kusamvetsetsana kwakukulu pa kapangidwe kake.

Mainjiniya ambiri amaganiza kuti ayenera kusintha n’kuyamba kugwiritsa ntchito injini ya “flat motor” popanga zipangizo zopyapyala. Zoona zake n’zakuti:

Mavuto ambiri a malo amathetsedwa ndi kapangidwe ka kulumikizana, osati kapangidwe ka injini.

Mwachitsanzo:

Mota ya φ8mm micro BLDC ili kale ndi kutalika kwa ~2.5mm yokha

Ndi FPCB, kutalika konse kwa dongosolo kumatha kukhala pansi pa 3mm

Palibe chifukwa chokonzanso kapangidwe ka nyumba

Ichi ndichifukwa chake kuphatikiza pamlingo wa dongosolo ndikofunikira kwambiri kuposa kukonza pamlingo wa zigawo.

Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri)

Q1: Kodi ma mota a flat ndi okwera mtengo kwambiri?

Inde, koma pang'ono chabe. Kusiyana kwakukulu kwa mtengo kumachokera ku kuphatikizana kwa FPCB, nthawi zambiri +15–25%. Komabe, izi nthawi zambiri zimachepetsedwa ndi ndalama zochepa zopangira ndi kusunga malo.

Q2: Kodi FPCB ndi yodalirika m'malo ogwedezeka?

Inde. Mabaibulo a FPCB amayesedwa maulendo opitilira 500,000 komanso kutsimikizika kwina kotopa kopindika. Mu ntchito zambiri, kudalirika kumakhala kofanana kapena kwabwino kuposa ma waya achikhalidwe.

Q3: Kodi ndingayike mota ya 8mm mu chipangizo cha 3mm?

Inde, koma ili pafupi ndi malire. Mota ya φ8×2.5mm yokhala ndi FPCB imatha kukwanira kutalika konse kwa ~3mm, koma kulekerera kapangidwe kuyenera kulamulidwa mosamala (malire ofunikira: +0.2mm).

Q4: Kodi ma mota owonda a BLDC angasinthidwenso?

Inde. Ma mota ena a φ5mm amatha kuchepetsedwa kuchoka pa 2.5mm kufika pa 1.8mm kutalika kutengera zomwe OEM ikufuna.

Pomaliza: Kapangidwe Kochepa Ndi Vuto la Dongosolo, Osati Vuto la Injini

Tsogolo la uinjiniya wa zida zazing'ono silikunena za kusankha mota woonda kwambiri — koma ndikunena za kukonza makina onse olumikizirana ndi magetsi.

Ma mota opanda burashi, makamaka akaphatikizidwa ndi ukadaulo wa FPCB, amapereka njira yothandiza kwambiri pamapangidwe amakono okhala ndi malo ochepa.

Ku Mtsogoleri, timayang'ana kwambiri kupereka zinthu zoonda kwambiriMayankho a BLDC kuyambira φ5mm mpaka φ12mm, yokhala ndi makulidwe ochepera 1.8mm, yopangidwira makamaka kuphatikiza kwa OEM.
