Motar da ba ta da buroshi DCtsarin shi ne m, da gudun ne m mafi barga, don haka a general, da wuya zuwa manyan gudun regulation.Saboda da mota yana da fadi da kewayon aikace-aikace da za a iya amfani da da yawa inji, shi wajibi ne don daidaita da gudun bisa ga daban-daban lokatai. Amma tsarin sarrafa injin dc maras gogewa da tsarin sarrafa saurin yana buƙatar kowa ya koya, don yin aiki da sauri:
1. Ta hanyar sarrafa tsarin da aka ba da wutar lantarki, ana rarraba coil ɗin da ke gaba zuwa rukuni kuma ana ƙarfafa halin yanzu don samar da filin maganadisu a cikin hanya guda.
2. Adadin igiyoyi na brushless dc motor guda uku ne, don haka kowane nau'i na "magani na Magnetic" za a iya gudanar da shi a cikin wani tsari na musamman don cimma tasirin juyawa na magnetic. a tsakiyar ko da yaushe yana da hali don kiyaye filin maganadisu a cikin hanya guda kuma zai juya tare da filin maganadisu mai juyawa.
H1H2H3 shine na'urori masu auna firikwensin Hall guda uku da aka sanya su a cikin tazarar iska na coil excitation, wanda ake amfani da shi azaman sinadari don gano filin maganadisu.Ana iya canza wutar lantarki bisa ga alkiblar filin maganadisu, kuma abin da ake fitarwa shine siginar dijital.
3. The stator coil yana da kuzari bisa ga jeri na gaba, kuma filin magnetic rotor da filin magnetic stator dole ne su sami Angle.Babu buƙatar yin hukunci ko motar dc ɗin ba ta fara ba, kawai buƙatar aiwatar da umarni na gaba bisa ga umarnin. zuwa yanayin aiki da aka aika ta Hall firikwensin.
Umarnin sa shine a aika nau'i-nau'i na coil a kunna da kashewa, ana samun waɗannan maɓallan ta hanyar transistor.
Ana iya samun jujjuyawar BLDC mai matakai uku ta hanyar ƙarfafawa ko yanke nau'ikan transistor guda uku a cikin wani tsari.
4. Yayin da rotor ke jujjuyawa, yuwuwar da aka jawo kowane coil yana tafiya daga mafi girma zuwa sifili kuma ya sake dawowa.Saboda lokacin da aka sami kuzari a cikin kishiyar, ƙarfin wutar lantarki na baya zai toshe ƙarfin juzu'i, don haka ɓangaren trapezoidal wave zai kasance. bayyana.A tabbatacce kuma korau irin ƙarfin lantarki na trapezoidal part na sifili ne akasin haka, don haka da aiki jihar stator mota za a iya ƙaddara ta gano tabbatacce kuma korau irin ƙarfin lantarki bayan da ƙarfin lantarki comparator.
Tun da ma'anar sifili yana tsakiyar tsakiyar trapezoid, ana iya sarrafa jujjuyawar BLDC bayan an fitar da siginar sarrafawa na tsarin lokaci mai dacewa bayan jinkiri na 30 °. Wannan yanayin sarrafawa baya buƙatar firikwensin Hall, kuma wayoyi uku zasu iya. fitar daBLDC.Idan waveform yana da ingantacciyar manufa, za'a iya samun magudanar wutar lantarki guda uku ta hanyar haɗa wutar lantarki kai tsaye.Don haka ana iya sarrafa injin dc maras goge.
5. Ƙayyade alkiblar farawa, ƙarfafa ƙananan nada a waccan hanyar da farko, sanya rotor ya juya zuwa wurin farawa a cikin ɗan gajeren lokaci, kuma ƙarfafa motar bisa ga jerin ayyuka masu zuwa.
Don inganta ingantaccen amfani da injin dc ba tare da gogewa ba, muna buƙatar koyo bisa ga yanayin amfani daban-daban, kulawa daban-daban da ƙa'idodin saurin sauri, haɓaka ingantaccen amfani da injin, sarrafawa da ka'idojin saurin sauri za a iya amfani da su don daidaita saurin gudu.
