Gwaro reMotokari Isina Mabhurashi: Mota DzeBLDC Dzakatetepa Dzemagadzirirwo Ane Nzvimbo Dzakamanikana

Dzidza kuti mota dzisina mabhurashi dzakati sandara (mota dzeBLDC dzakatetepa) dzinobatsira sei mainjiniya kugadzirisa zvipingamupinyi zvenzvimbo mumidziyo yemazuva ano. Ongorora chimiro, kubatanidzwa kweFPCB, mashandisirwo, uye mazano ekusarudza OEM.

Pfungwa Huru dzeChinyorwa Chino

"Kutetepa" kwava kukosha kupfuura "diki" mukugadzirwa kwemidziyo yemazuva ano

Mota dzisina mabhurashi dzakatsetseka dzinoderedza kukwirira nekushandisa zvimiro zveL/D zvakaderera

Kubatana kweFPCB kunogona kuchengetedza nzvimbo yakamira kusvika 0.5–1mm

Hazvisi zvese zvinoshandiswa zvitete zvinoda chimiro chakakosha che "flat motor"

Mota dzemhando yepamusoro dzeBLDC (φ5–12mm) dzakatotetepa zvakanyanya muzviitiko zvakawanda

Zvishandiso zvikuru zvinosanganisira zvinopfekwa, zvishandiso zveTWS, uye zvishandiso zvekurapa zvinobatwa nemaoko

Dhizaini yakakodzera yekupisa uye yekubatanidza yakakosha kupfuura chimiro chemota

Sarudzo yeOEM inofanira kutarisa pakubatanidzwa kwesisitimu, kwete chete miganhu yemota

Nhanganyaya: Nei "Vatete" Vava Dambudziko Rekugadzira Magadzirirwo Matsva

Mumakore mashoma apfuura, mafambiro makuru emagetsi evatengi nemidziyo yekurapa haasisiri "diki" chete - asi ari kutetepa.

Mahedhifoni eTWS ari kudzikira kubva pa12mm kusvika pa8mm. Mawachi esmartwatches anofanira kubatanidza masensa akawanda mumiviri mitete kwazvo ye4–6mm. Midziyo yekurapa inobatwa nemaoko iri kuramba ichiwedzera kusimba uku ichiramba ichishanda zvakanaka. Kunyangwe michina yeindasitiri yava kudziviswa nekureba kwayo.

Mumagadzirirwo aya, mainjiniya havasi kubvunza kuti "mota yacho ingava diki sei?" asi kuti:

"Tingaisa sei injini munzvimbo yakamanikana zvikuru?"

Apa ndipo panonyanya kukosha mota dzisina mabhurashi dzakati sandara (mota dzeBLDC dzakatetepa).

Chii chinonzi mota isina mabhurashi?

Izwi rekuti "flat brushless motor" (kana kuti pancake BLDC motor) harina kunyatsoenderana muindasitiri. Vagadziri vakasiyana vanoritsanangura zvakasiyana, asi mukuita kweinjiniya, rinowanzoreva pfungwa mbiri huru:

1. Kusatsetseka kweMagadzirirwo (Chiyero cheL/D Chakaderera)

Mota dzechinyakare dzecylindrical dzinowanzova nechiyero cheL/D (kureba kusvika padhayamita) chikuru kupfuura 1.

Mota dzakatsetseka dzinodzosera chimiro ichi shure:

Dhayamita yakakura

Kureba kwakaderera zvakanyanya

Chiyero cheL/D chiri pasi pe1

Semuenzaniso, φ8×2.5mmLBM0825Mota ye micro BLDC ine chiyero cheL/D che0.31 — yatove yakati sandara zvakanyanya maererano nezvinodiwa neindasitiri.

Izvi zvinoratidza nzwisiso inokosha:

Kazhinji, haudi "mota yakatsetseka" yakakosha — mota dzemhando yepamusoro dzeBLDC dzakatotetepa zvakanyanya.

2. Kubatana-Kwakavakirwa paFlatness (Kubatanidzwa kweFPCB)

Mukugadzirwa kweOEM chaiyo, dambudziko guru rekukwirira kazhinji harisi mota pachayo - asi waya.

Waya dzekare dzinoda nzvimbo yakakombama ye 2–4mm. Nzvimbo iyi yakawedzerwa inowanzova chikonzero chakavanzika chekuti chigadzirwa chisakwanise kusvika pakukora kwacho.

Mabhodhi eFlexible Printed Circuit Boards (FPCB) anogadzirisa dambudziko iri nekuita zvinotevera:

Kubvisa nzvimbo yekukotama kwewaya

Kubvumira kubatana kwePCB kwakananga pasi

Kuderedza kukwirira kwese kwemuchina ne 0.5–1mm

Mukugadzirwa kwemidziyo mitete, chimiro chekubatanidza chakakosha sechimiro chemota.

Mashandisirwo Akakosha eThin BLDC Motors

Mota dzisina mabhurashi hadzisi mhinduro dzinoshanda kune vese. Kukosha kwadzo kunoonekwa chete kana kukwirira kwava dambudziko guru.

1. MaTWS Earbuds & Makesi Ekuchaja (≤5mm kureba)

Kureba kunowanikwa: 3–5mm

Mhinduro yakajairika: φ5–6mm micro BLDC

Muenzaniso:LBM0525Mota ye φ5×2.5mm ine kubatana kwepasi kweFPCB

Zvinodiwa zvikuru:

Kudedera kweruzha rwakaderera

Mhinduro ye "haptic" yakakwana

2. Mawachi eSmart & Anopfekwa (≤4mm kureba)

Ukobvu hwemukati hwakaganhurirwa zvakanyanya

Kubatana kweFPCB kwava kwakakosha

Sarudzo yakajairika: φ6mm BLDC yakatetepa zvakanyanya

Zvinodiwa zvikuru:

Simba rakaderera remuchadenga

Kuchinja simba rekudzungaira

Kuvimbika kwakanyanya munzvimbo dzekufamba

3. Midziyo Yekurapa Inobatwa Nemaoko (kureba kwe8–15mm)

Zvipingamupinyi zvepakati nepakati

Saizi dzemota dzakajairika: φ8–12mm

Kutarisa kwakaringana pamusoro pesimba rekudengenyeka uye kugadzikana

Zvinodiwa zvikuru:

Kubuda kwetorque yakagadzikana

Kuvimbika kwenguva refu

4. Mapiritsi Matete & Mapaneru Emaindasitiri (≤8mm kureba)

Kutarisa kunochinja kubva pahukuru kuenda pakutarisira kupisa

Mota dzakatetepa dzakakura (φ10–12mm)

Yakagadzirirwa kushanda nguva dzose

Zvinodiwa zvikuru:

Kupisa kupisa kuburikidza ne radial housing

Kudzora kweEMC

Kushanda kwenguva refu kwakagadzikana

Nei FPCB Yakakosha Mukugadzira Mota Dzakatetepa

Mumapurojekiti mazhinji eOEM, mainjiniya anotarisa chete pahukuru hwemota. Zvisinei, mumamiriro ezvinhu chaiwo ekubatanidza, dhizaini yekubatanidza inowanzo sarudza kubudirira kana kukundikana.

FPCB inogadzirisa matambudziko matatu makuru einjiniya:

1. Inobvisa marara anodzivirira mativi ose

Waya dzesimbi dzinoda nzvimbo yekukombama.

FPCB inobvisa izvi zvachose, zvichiita kuti pave nekubatanidzwa kwakasimba.

2. Inovandudza Kushanda Nesimba Mukugadzira

Kubatanidza waya yechinyakare: matanho akawanda

Mhinduro yeFPCB: danho rimwe chete rekubatanidza

Kusvika ku30% kuvandudzwa kwekushanda zvakanaka kwemusangano

3. Inowedzera Kuvimbika Kwemuchina

Waya dzakatetepa munzvimbo dzinodengenyeka dzinowanzo kundikana nekuda kwekuneta.

FPCB inogovera kushushikana zvakaenzana uye inovandudza zvakanyanya kugara kwenguva refu.

Mota Yakatsetseka Inodiwa Nguva Dzose Here?

Kwete — uye uku kusanzwisisana kwakakomba pakugadzira.

Mainjiniya mazhinji anofunga kuti vanofanira kushandisa "mota yakatsetseka" pavanenge vachigadzira michina mitete. Muchokwadi:

Matambudziko mazhinji emuchadenga anogadziriswa nekugadzirwa kwekubatanidza, kwete chimiro chemota.

Semuyenzaniso:

Mota ye φ8mm micro BLDC yatove nekukwirira kwe ~2.5mm chete

NeFPCB, kukwirira kwese kwesystem kunogona kugara pasi pe3mm

Hapana kudiwa kwekugadzirisa patsva kwechivako

Ndosaka kubatanidzwa kwechikamu chesystem kuchikosha kupfuura kugadzirisa chikamu chechikamu.

Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)

Mubvunzo 1: Mota dzakapfava dzinodhura here?

Ehe, asi zvishoma chete. Musiyano mukuru wemutengo unobva mukubatanidzwa kweFPCB, kazhinji +15–25%. Zvisinei, izvi zvinowanzo deredzwa nekudzikira kwemari yekubatanidza uye kuchengetedza nzvimbo.

Mubvunzo wechipiri: FPCB yakavimbika here munzvimbo dzinodedera?

Ehe. Mavhezheni eFPCB anoedzwa kweanopfuura 500,000 cycles uye mamwe magadzirirwo ekuwedzera ekukotama. Muzvishandiso zvakawanda, kuvimbika kwakaenzana kana kuti kuri nani pane waya dzechinyakare.

Mubvunzo wechitatu: Ndingaisa mota ye8mm mumudziyo we3mm here?

Ehe, asi yava pedyo nemuganhu. Mota ye φ8×2.5mm ine FPCB inogona kukwana pahurefu hwese hwe ~3mm, asi kushivirira kwedhizaini kunofanira kudzorwa nokungwarira (muganhu unokurudzirwa: +0.2mm).

Q4: Mota dzeBLDC dzakatetepa dzinogona kugadziriswa here?

Ehe. Mamwe mamota e φ5mm anogona kuderedzwa kubva pa2.5mm kusvika 1.8mm kukwirira zvichienderana nezvinodiwa neOEM.

Mhedziso: Kugadzira Zvitete Dambudziko reSisitimu, Kwete Dambudziko reMotokari

Remangwana rekugadzira michina midiki harisi rekusarudza mota yakatetepa kupfuura dzose — asi rekugadzirisa sisitimu yese yekubatanidza michina nemagetsi.

Mota dzisina mabhurashi dzakatsetseka, kunyanya kana dzikasanganiswa netekinoroji yeFPCB, dzinopa mhinduro inoshanda zvikuru kumagadzirirwo emazuva ano ane nzvimbo shoma.

KuMutungamiriri, tinonyanya kutarisa pakupa zvinhu zvakatetepa zvakanyanyaMhinduro dzeBLDC dzinotangira pa φ5mm kusvika pa φ12mm, ine ukobvu hwakaderera kusvika 1.8mm, yakagadzirirwa zvakananga kubatanidzwa kweOEM.
