Ubuyobozi bwa moteri idafite brushless: Moteri nto za BLDC zo mu rwego rwo hejuru mu buryo bugabanya umwanya

Menya uburyo moteri zidafite uburoso (moteri nto za BLDC) zifasha injeniyeri gukemura ikibazo cy'umwanya mu bikoresho bigezweho. Suzuma imiterere, guhuza FPCB, porogaramu, n'inama zo guhitamo OEM.

Ingingo z'ingenzi z'iyi ngingo

"Indashyikirwa" ubu ni ingenzi kurusha "intoya" mu miterere y'ibikoresho bigezweho

Moteri zidafite uburoso zigabanya uburebure hakoreshejwe imiterere y'ikigereranyo cya L/D gito

Guhuza FPCB bishobora kuzigama umwanya uhagaze ugera kuri 0.5–1mm

Ntabwo porogaramu zose zoroheje zisaba imiterere yihariye ya "moteri igororotse"

Moteri zisanzwe za BLDC (φ5–12mm) zimaze kuba nto cyane mu bihe byinshi

Porogaramu z'ingenzi zirimo ibikoresho byo kwambara, ibikoresho bya TWS, n'ibikoresho byo kwa muganga bifatwa mu ntoki

Igishushanyo gikwiye cy'ubushyuhe n'uburyo bwo guhuza ni ingenzi cyane kuruta imiterere ya moteri

Guhitamo OEM bigomba kwibanda ku guhuza sisitemu, ntabwo ari ingano ya moteri gusa

Intangiriro: Impamvu "Ubwoya" bwabaye ikibazo gishya cyo gushushanya

Mu myaka mike ishize, icyerekezo gikomeye mu bikoresho by'ikoranabuhanga n'ibikoresho by'ubuvuzi ntabwo kikiri "kito" gusa - ahubwo ni gito cyane.

Utwuma two mu matwi twa TWS turimo kugabanuka kuva kuri mm 12 kugeza kuri mm 8. Amasaha y'ubwenge agomba gushyiramo sensor nyinshi mu duti tworoheje cyane twa mm 4–6. Ibikoresho by'ubuvuzi bifatwa mu ntoki birimo kuba bito mu gihe bikomeza gukora neza. Ndetse n'ibikoresho by'inganda ubu bigizwe n'imbogamizi kubera uburebure buke.

Muri ubu buryo, injeniyeri ntibakibaza bati “ese moteri ishobora kuba ntoya gute?” ahubwo barimo kubaza bati:

"Ni gute twashyira moteri mu mwanya muto cyane uhagaze?"

Aha niho moteri zidafite uburoso (moteri nto za BLDC) ziba ingenzi.

Moteri idafite brush itembagara ni iki?

Ijambo "moteri idafite uburoso" (cyangwa moteri ya pancake BLDC) ntabwo rikoreshwa mu buryo busanzwe mu nganda. Inganda zitandukanye zibisobanura mu buryo butandukanye, ariko mu ikoranabuhanga, akenshi yerekeza ku ngingo ebyiri z'ingenzi:

1. Ubugari bw'inyubako (Igipimo cyo hasi cya L/D)

Moteri zisanzwe zimeze nk'uruziga ubusanzwe zifite igipimo cya L/D (uburebure kugeza ku murambararo) kirenze 1.

Moteri zigororotse zihindura iyi miterere:

Ingano ni nini

Uburebure bwagabanutse cyane

Igipimo cya L/D kiri munsi ya 1

Urugero, φ8×2.5mmLBM0825Moteri ya micro BLDC ifite igipimo cya L/D cya 0.31 — imaze kuba nto cyane ukurikije ibipimo by’inganda.

Ibi bigaragaza igitekerezo cy'ingenzi:

Kenshi na kenshi, ntukeneye "moteri igororotse" yihariye — moteri zisanzwe za BLDC ziba zaragabanutse cyane.

2. Uburyo bwo guhuza bushingiye ku guhuza (FPCB Integration)

Mu miterere nyayo ya OEM, ikibazo gikomeye cy’uburebure akenshi si moteri ubwayo - ahubwo ni insinga.

Insinga zisanzwe zisaba ko zipfunyika hagati ya mm 2–4. Iki kibanza cy'inyongera gikunze kuba impamvu ihishe ituma ibicuruzwa bidashobora kugera ku bunini bwabyo.

Ibikoresho byo mu bwoko bwa Flexible Printed Circuit Boards (FPCB) bikemuye iki kibazo binyuze mu:

Gukuraho umwanya wo kunama insinga

Kwemerera guhuza PCB yo hasi mu buryo butaziguye

Kugabanya uburebure bw'igikoresho cyose ho 0.5–1mm

Mu miterere y'ibikoresho bito, imiterere y'itumanaho ni ingenzi kimwe n'imiterere ya moteri.

Imikoreshereze y'ingenzi ya Thin BLDC Motors

Moteri zitagira uburoso zidafite brush si ibisubizo rusange. Agaciro kazo kagaragara gusa iyo uburebure bubaye umupaka ukomeye.

1. Utwuma two mu matwi twa TWS n'udusanduku two gusharija (uburebure bwa ≤5mm)

Uburebure buboneka: 3–5mm

Umuti usanzwe: φ5–6mm micro BLDC

Urugero:LBM0525Moteri ya φ5×2.5mm ifite aho ihurira na FPCB hasi

Ibisabwa by'ingenzi:

Ikoreshwa ry'ingufu rike cyane

Urusaku ruke rutemba

Ibisubizo bigufi bya haptic

2. Amasaha y'ubwenge n'ibikoresho byo kwambara (uburebure bwa ≤4mm)

Ubugari bw'imbere bufite ingano nto cyane

Guhuza na FPCB biba ingenzi

Amahitamo asanzwe: φ6mm BLDC nto cyane

Ibisabwa by'ingenzi:

Ingufu nke zo guhagarara

Ubukana bw'ihindagurika rishobora guhindurwa

Kwizerwa cyane mu bidukikije bigenda

3. Ibikoresho byo kwa muganga bifatwa n'intoki (uburebure bwa mm 8–15)

Inzitizi z'umwanya uciriritse

Ingano zisanzwe za moteri: φ8–12mm

Kwibanda ku buryo bungana ku mbaraga zo guhindagura no guhagarara neza

Ibisabwa by'ingenzi:

Umusaruro uhamye wa torque

Kwizerwa kw'igihe kirekire

Urusaku rw'amajwi ruri hasi

4. Ibinini bito n'udupira tw'inganda (uburebure bwa ≤8mm)

Ibyibandwaho bihinduka kuva ku bunini kugera ku gucunga ubushyuhe

Moteri nini z'umurambararo muto (φ10–12mm)

Byagenewe gukora buri gihe

Ibisabwa by'ingenzi:

Gukwirakwiza ubushyuhe binyuze mu nzu y'imirasire

Kugenzura EMC

Imikorere ihamye y'igihe kirekire

Impamvu FPCB ari ingenzi mu gushushanya moteri nto

Mu mishinga myinshi ya OEM, injeniyeri zibanda gusa ku bipimo bya moteri. Ariko, mu miterere nyayo y'iteraniro, imiterere y'ihuza akenshi igaragaza intsinzi cyangwa gutsindwa.

FPCB ikemura ibibazo bitatu by'ingenzi by'ubwubatsi:

1. Ikuraho imyanda ivanwaho ihagaze

Insinga z'icyuma zisaba umwanya wo kugonda.

FPCB ikuraho ibi burundu, bituma habaho guhuza neza.

2. Binoza imikorere myiza mu nganda

Gusodesha insinga gakondo: intambwe nyinshi

Igisubizo cya FPCB: intambwe imwe yo guhuza

Kugeza kuri 30% by'ubushobozi bwo guteranya

3. Byongera ubwiringiro mu by'ikoranabuhanga

Insinga nto mu bice bihindagurika zikunze kunanirwa bitewe n'umunaniro.

FPCB ikwirakwiza stress neza kandi ikongera cyane kuramba.

Ese moteri idafite ingano ihora ari ngombwa?

Oya — kandi iki ni ikibazo gikomeye cyo kutumvikana ku gishushanyo mbonera.

Abahanga benshi bibwira ko bagomba guhindura bakajya kuri "moteri igororotse" mu gihe bashushanya ibikoresho bito. Mu by'ukuri:

Ibibazo byinshi by’umwanya bikemurwa n’imiterere y’aho bihurira, ntabwo ari moteri.

Urugero:

Moteri ya PH8mm micro BLDC imaze kugira uburebure bwa ~2.5mm gusa

Ukoresheje FPCB, uburebure bwose bwa sisitemu bushobora kuguma munsi ya mm 3

Nta gikenewe kuvugurura inyubako

Iyi ni yo mpamvu guhuza sisitemu ari ingenzi cyane kuruta kunoza urwego rw'ibice.

Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa)

Q1: Ese moteri zidafite imashini zihenze cyane?

Yego, ariko gato gusa. Itandukaniro nyamukuru ry'ibiciro rituruka ku guhuza FPCB, ubusanzwe +15–25%. Ariko, ibi bikunze gukurwaho no kugabanuka kw'ibiciro byo guteranya no kuzigama umwanya.

Ikibazo cya 2: Ese FPCB yizewe mu bidukikije bihindagurika?

Yego. Verisiyo za FPCB zigeragezwa ku nshuro zirenga 500.000 no kwemeza ko icyuma gifata umuvuduko wo kugonga kigenda gihinduka. Mu bikorwa byinshi, ubwizerwe buringaniye cyangwa buruta ubw'insinga zisanzwe.

Q3: Ese nshobora gushyira moteri ya 8mm mu gikoresho cya 3mm?

Yego, ariko iri hafi y'aho ntarengwa. Moteri ya φ8×2.5mm ifite FPCB ishobora kwinjira mu burebure bwose bwa ~3mm, ariko ubushobozi bwo kwihanganira imiterere yayo bugomba kugenzurwa neza (urugero rwatanzwe ni +0.2mm).

Q4: Ese moteri nto za BLDC zishobora guhindurwa kurushaho?

Yego. Moteri zimwe na zimwe za φ5mm zishobora kugabanuka kuva kuri 2.5mm kugera kuri 1.8mm bitewe n'ibisabwa na OEM.

Umwanzuro: Igishushanyo gito ni ikibazo cya sisitemu, si ikibazo cya moteri

Ahazaza h’ikoranabuhanga ry’ibikoresho bito ntabwo ari uguhitamo moteri ntoya cyane - ahubwo ni ugukoresha neza uburyo bwose bwo guhuza ibyuma n’amashanyarazi.

Moteri zidafite uburoso, cyane cyane iyo zihujwe n'ikoranabuhanga rya FPCB, zitanga igisubizo cyiza cyane ku miterere igezweho y'ahantu hato na hato.

Muri Leader, twibanda ku gutanga ibintu bito cyaneIbisubizo bya BLDC kuva kuri φ5mm kugeza kuri φ12mm, ifite ubugari buri hasi bwa 1.8mm, yagenewe byihariye guhuza na OEM.
