Isikhokelo seMoto engenaBrashi eSicaba: IiMoto zeBLDC eziThin zoYilo oluNciphiselwe Indawo

Funda indlela iimoto ezingenamabhrashi ezisicaba (iimoto zeBLDC ezibhityileyo) ezinceda ngayo iinjineli ukusombulula imida yendawo kwizixhobo zanamhlanje. Hlola ulwakhiwo, ukuhlanganiswa kweFPCB, usetyenziso, kunye neengcebiso zokukhetha i-OEM.

Amanqaku aphambili kweli nqaku

"Ubunzima" ngoku bubaluleke ngakumbi kune "buncinci" kuyilo lwezixhobo zanamhlanje

Iimoto ezingenamabhulashi ezisicaba zinciphisa ubude ngokusebenzisa izakhiwo eziphantsi zomlinganiselo we-L/D

Uqhagamshelo lwe-FPCB lunokonga ukuya kuthi ga kwi-0.5–1mm yendawo ethe nkqo

Ayizizo zonke izicelo ezincinci ezifuna isakhiwo esikhethekileyo "semoto ethe tyaba"

Iimoto ze-BLDC eziqhelekileyo (φ5–12mm) sele zincinci kakhulu kwiimeko ezininzi

Izicelo eziphambili ziquka izinto ezinxitywayo, izixhobo ze-TWS, kunye nezixhobo zonyango eziphathwayo

Uyilo olufanelekileyo lobushushu kunye noqhagamshelwano lubaluleke ngaphezu kobume benjini

Ukukhethwa kwe-OEM kufanele kugxile ekudityanisweni kwenkqubo, kungekuphela nje kobukhulu bemoto

Intshayelelo: Kutheni "Ubunzima" Buye Baba Ngumngeni Omtsha Woyilo

Kwiminyaka embalwa edlulileyo, umkhwa omkhulu kwii-elektroniki zabathengi kunye nezixhobo zonyango awusengo "mncinci" nje kuphela - unciphile.

Ii-earbuds ze-TWS ziyancipha ukusuka kwii-housings ze-12mm ukuya kwi-8mm. Ii-smartwatches kufuneka zidibanise ii-sensors ezingaphezulu kwimizimba emincinci kakhulu ye-4–6mm. Izixhobo zonyango eziphathwayo ziya zisiba ncinci ngakumbi ngelixa zigcina ukusebenza kakuhle. Nezixhobo zoshishino ngoku zithintelwe yimida yokuphakama.

Kwezi zakhiwo, iinjineli azisabuzi ukuba “ingaba ncinci kangakanani le moto?” kodwa endaweni yoko:

"Singayifaka njani injini kwindawo ethe nkqo elinganiselweyo?"

Kulapho ke iimoto ezingenamabhrashi ezithe tyaba (iimoto zeBLDC ezincinci) ziba zibalulekile khona.

Yintoni iMoto engenaBrashi eSicaba?

Igama elithi “i-flat brushless motor” (okanye i-pancake BLDC motor) alisetyenziswanga ngokungqongqo kushishino. Abavelisi abahlukeneyo balichaza ngokwahlukileyo, kodwa kwindlela yobunjineli, lidla ngokubhekisa kwiingcamango ezimbini eziphambili:

1. Ulwakhiwo oluthe tyaba (Umlinganiselo ophantsi we-L/D)

Iimoto zesintu ezisilinda zihlala zine-L/D (ubude ukuya kububanzi) ratio engaphezulu kwe-1.

Iimoto ezisicaba zijika umva olu lwakhiwo:

Ububanzi bukhulu

Ukuphakama kuncitshiswe kakhulu

Umlinganiselo we-L/D ungaphantsi kwe-1

Umzekelo, i-φ8×2.5mmLBM0825Imoto ye-micro BLDC inomlinganiselo we-L/D we-0.31 — sele ithambile kakhulu ngokwemigangatho yoshishino.

Oku kubonisa ingqiqo ebalulekileyo:

Kwiimeko ezininzi, awudingi "imoto ethe tyaba" ekhethekileyo — iimoto ezincinci zeBLDC eziqhelekileyo sele zibhityile kakhulu.

2. Ubudlelwane obusekelwe kwi-Flatness (Udibaniso lwe-FPCB)

Kwindlela yoyilo lwe-OEM yokwenyani, ingxaki enkulu yokuphakama ayisoloko iyimoto ngokwayo - kodwa ziintambo.

Iingcingo zentsimbi zemveli zifuna ukugoba okuphakathi kwe-2–4mm. Esi sithuba songezelelweyo sidla ngokuba sisizathu esifihlakeleyo sokuba imveliso ingakwazi ukufikelela kubukhulu bayo.

IiBhodi zeSekethe eziPrintiweyo eziGuquguqukayo (FPCB) zisombulula le ngxaki ngokuthi:

Ukususa indawo yokugoba ucingo

Ukuvumela uqhagamshelo lwe-PCB olusezantsi ngqo

Ukunciphisa ukuphakama kwesixhobo sisonke nge-0.5–1mm

Kuyilo lwesixhobo esincinci, ulwakhiwo loqhagamshelo lubaluleke ngendlela efanayo nolwakhiwo lwemoto.

Izicelo eziphambili zeThin BLDC Motors

Iimoto ezingenamabhrashi azizozisombululo ezisetyenziswa ngumntu wonke. Ixabiso lazo livela kuphela xa ubude busiba ngumqobo ongqongqo.

Iimoto ezinkulu ezinobubanzi obuncinci (φ10–12mm)

Yenzelwe ukusebenza rhoqo

Iimfuno eziphambili:

Ukusasazwa kobushushu nge-radial housing

Ulawulo lwe-EMC

Ukusebenza okuzinzileyo kwexesha elide

Kutheni i-FPCB ibalulekile kuyilo lweeMoto eziThin

Kwiiprojekthi ezininzi ze-OEM, iinjineli zigxila kuphela kubukhulu beemoto. Nangona kunjalo, kwiimeko zokwenyani zokuhlanganisa, uyilo loqhagamshelo ludla ngokugqiba impumelelo okanye ukungaphumeleli.

I-FPCB isombulula iingxaki ezintathu ezinkulu zobunjineli:

1. Isusa inkunkuma ecacileyo ethe nkqo

Iingcingo zentsimbi zifuna indawo yokugoba.

I-FPCB iyisusa ngokupheleleyo le nto, ivumela ukuhlanganiswa okuqinileyo.

2. Iphucula ukusebenza kakuhle kweMveliso

Ukutywina ucingo lwendabuko: amanyathelo amaninzi

Isisombululo se-FPCB: inyathelo elinye loqhagamshelo

Ukuphuculwa kokusebenza kakuhle kwendibano ukuya kuthi ga kwi-30%

3. Yonyusa ukuthembeka koomatshini

Iintambo ezibhityileyo kwiindawo zokungcangcazela zihlala zingasebenzi kakuhle ngenxa yokudinwa.

I-FPCB isasaza uxinzelelo ngokulinganayo kwaye iphucula kakhulu ukuqina.

Ngaba Imoto Ethe tyaba Isoloko Iyimfuneko?

Hayi — kwaye oku kukungaqondi kakuhle koyilo.

Iinjineli ezininzi zicinga ukuba kufuneka zitshintshele kwi-"flat motor" xa ziyila izixhobo ezincinci. Enyanisweni:

Uninzi lweengxaki zendawo zisonjululwa ngoyilo loqhagamshelo, kungekhona ulwakhiwo lwemoto.

Umzekelo:

Imoto ye-BLDC encinci ye-φ8mm sele inobude obuyi-~2.5mm kuphela

Nge-FPCB, ubude benkqubo iyonke bunokuhlala ngaphantsi kwe-3mm

Akukho mfuneko yoyilo olutsha lwesakhiwo

Yingakho ukuhlanganiswa kwenqanaba lenkqubo kubaluleke ngakumbi kunokulungiswa kwenqanaba leenxalenye.

Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo)

Q1: Ngaba iimoto ezisicaba zibiza kakhulu?

Ewe, kodwa kancinci nje. Umahluko omkhulu weendleko uvela ekuhlanganisweni kwe-FPCB, ngesiqhelo +15–25%. Nangona kunjalo, oku kudla ngokulungiswa kukunciphisa iindleko zokuhlanganisa kunye nokonga indawo.

Umbuzo 2: Ngaba i-FPCB ithembekile kwiindawo zokungcangcazela?

Ewe. Iinguqulelo ze-FPCB zivavanywa kwiindlela ezingaphezulu kwama-500,000 kunye nokuqinisekiswa kokudinwa okongeziweyo. Kwiinkqubo ezininzi, ukuthembeka kuyafana okanye kungcono kuneentambo zendabuko.

Umbuzo 3: Ndingayifaka i-motor ye-8mm kwisixhobo se-3mm?

Ewe, kodwa ikufutshane nomda. Injini ye-φ8×2.5mm ene-FPCB ingangena kubude obupheleleyo obuyi-~3mm, kodwa ukunyamezela uyilo kufuneka kulawulwe ngononophelo (umda ocetyiswayo: +0.2mm).

Q4: Ngaba iimoto ezincinci ze-BLDC zingenziwa ngokwezifiso ngakumbi?

Ewe. Ezinye iimoto ze-φ5mm zinokuncitshiswa ukusuka kwi-2.5mm ukuya kwi-1.8mm ubude ngokuxhomekeke kwiimfuno ze-OEM.

Isiphelo: Uyilo oluThin yingxaki yenkqubo, hayi ingxaki yemoto

Ikamva lobunjineli bezixhobo ezincinci alikho malunga nokukhetha eyona moto incinci kakhulu — limalunga nokwenza ngcono yonke inkqubo yokudibanisa oomatshini kunye nombane.

Iimoto ezingenamabhrashi athambileyo, ingakumbi xa zidityaniswe netekhnoloji ye-FPCB, zibonelela ngesisombululo esisebenzayo kakhulu kwiindlela zanamhlanje zoyilo oluneendawo ezixineneyo.

KwiNkokheli, sigxile ekunikezeleni izinto ezincinci kakhuluIzisombululo ze-BLDC eziqala kwi-φ5mm ukuya kwi-φ12mm, enobukhulu obuphantsi njenge-1.8mm, yenzelwe ngokukodwa ukuhlanganiswa kwe-OEM.
