Hanyar sarrafa motar dc mara gogewa da kuma daidaita gudu

Motar Dc mara gogewaTsarin yana da ma'ana, saurinsa ya fi karko, don haka gabaɗaya, ba kasafai yake daidaita saurin ba. Saboda injin yana da aikace-aikace iri-iri kuma injuna da yawa za su iya amfani da shi, ya zama dole a daidaita saurinsa bisa ga lokatai daban-daban. Amma hanyar sarrafa motar dc mara gogewa da kuma daidaita saurin tana buƙatar kowa ya koya, domin a yi amfani da ita cikin sauri:

1. Ta hanyar sarrafa tsarin da aka samar da wutar lantarki, ana raba wutar lantarki mai adawa zuwa rukuni kuma ana samar da wutar lantarki don samar da filin maganadisu a cikin wannan alkibla.

2. Adadin sandunan motar dc mara gogewa guda uku ne, ta yadda kowace sandar "magnetic" za a iya gudanar da ita a wani tsari don cimma tasirin juyawar filin maganadisu. A ƙarƙashin aikin filin maganadisu, na'urar maganadisu ta dindindin a tsakiya koyaushe tana da halin kiyaye filin maganadisu a hanya ɗaya kuma za ta juya tare da filin maganadisu mai juyawa.

H1H2H3 na'urori ne guda uku na Hall da aka sanya a cikin gibin iska na na'urar motsa jiki, wanda ake amfani da shi azaman wani abu don gano filin maganadisu. Ana iya canza ƙarfin lantarki bisa ga alkiblar filin maganadisu, kuma fitarwa siginar dijital ce.

3. Ana kunna na'urar stator bisa ga jerin da ke gaba, kuma filin maganadisu na rotor da filin maganadisu na stator dole ne su sami kusurwa. Babu buƙatar yin hukunci ko injin dc mara gogewa ya fara aiki, kawai kuna buƙatar aiwatar da umarni na gaba bisa ga yanayin aiki da firikwensin Hall ya mayar.

Umarninsa shine a aika nau'i uku na na'ura mai aiki da wuta, ana samun waɗannan makullan ta hanyar transistor.

Ana iya cimma juyawar BLDC mai matakai uku ta hanyar ƙarfafawa ko yanke nau'ikan transistor guda uku a cikin wani tsari.

4. Yayin da na'urar juyawa ke juyawa, ƙarfin da kowace na'ura ke haifarwa yana tafiya daga mafi girma zuwa sifili sannan ya sake dawowa. Domin lokacin da aka kunna na'urar a akasin haka, ƙarfin lantarki na baya zai toshe ƙarfin lantarki na baya, don haka ɓangaren raƙuman trapezoidal zai bayyana. Ƙarfin lantarki mai kyau da mara kyau na ɓangaren trapezoidal na sifili akasin haka ne, don haka ana iya tantance yanayin aiki na stator ɗin motar ta hanyar gano ƙarfin lantarki mai kyau da mara kyau bayan mai kwatanta ƙarfin lantarki.

Tunda wurin sifili yana tsakiyar trapezoid, ana iya sarrafa juyawar BLDC bayan an fitar da siginar sarrafawa ta jerin lokaci mai dacewa bayan jinkiri na 30°. Wannan yanayin sarrafawa baya buƙatar firikwensin Hall, kuma wayoyi uku na iya tuƙa shi.BLDCIdan tsarin raƙuman ruwa ya dace sosai, ana iya samun lanƙwasa ƙarfin lantarki guda uku ta hanyar haɗa ƙarfin lantarki kai tsaye. Don haka ana iya sarrafa motar dc mara gogewa.

5. Kayyade alkiblar farawa, fara kunna na'urar da ke ƙasa a wannan alkiblar, sa rotor ya juya zuwa wurin farawa cikin ɗan gajeren lokaci, sannan ya kunna injin bisa ga jerin ayyuka masu zuwa.

Domin inganta amfani da injin dc mara gogewa, muna buƙatar koyon yadda ake amfani da shi bisa ga yanayi daban-daban na amfani, da kuma daidaita saurin gudu, da kuma inganta ingancin amfani da injin, ana iya amfani da hanyar sarrafawa da kuma daidaita saurin don daidaita saurin.
