Sida isha korontada ee qalabka korontada ama mishiinada kala duwan, shaqada muhiimka ah ee matoorku waa in ay keento qulqulka wadista.

Inkasta oo wax-dhimeeyaha meeraha inta badan loo isticmaalo iyada oo lala kaashanayo matoorada servo iyo matoorada stepper, aqoonta xirfadeed ee matoorada ayaa weli ah mid caan ah.Sidaa darteed, waan ka samri waayey inaan arko "soo koobida hawlgalka mootada ugu awoodda badan taariikhda".Soo noqo si aad qof walba ula wadaagto.

Matoorada Tooska ah ee Tooska ah ee bilaa Brushless (BLDCM) waxa ay meesha ka saartaa cilladaha soo jireenka ah ee matoorada DC-ga ee la caday oo waxa uu ku beddelaa rotors-ka mishiinka mishiinka rotorska qalabka elektarooniga ah.Sidaa darteed, matoorrada tooska ah ee hadda bilaa burushka ah waxay leeyihiin sifooyin xawaare doorsooma oo aad u wanaagsan iyo sifooyin kale oo matoorada DC ah.Waxa kale oo ay leedahay faa'iidooyinka qaab-dhismeedka fudud ee isgaadhsiinta AC motor, ma laha olol isdhaafsi, hawlgal la isku halayn karo iyo dayactir fudud.
Mabaadi'da aasaasiga ah iyo hagaajinta algorithms.

Xeerarka kontoroolka mootada BLDC waxay xakameeyaan booska iyo nidaamka matoorka rotor-ka ee matoorku u horumariyo hagaajinta.Dhaqdhaqaaqa heerka kontoroolka xiran ee xiran, waxaa jira laba xeer oo dheeraad ah, taas oo ah, cabbirka saxda ah ee xawaaraha rotor-ka/ama dhaqdhaqaaqa hadda jira iyo calaamada PWM si loo xakameeyo awoodda wax soo saarka ee heerka dhaqdhaqaaqa.

Matoorka BLDC wuxuu dooran karaa isku xigxiga dhinaca ama xarunta maamulka si uu u kala dabo calaamada PWM sida waafaqsan xeerarka codsiga.Codsiyada intooda badani waxay kaliya ku beddelaan hawlgalka dhabta ah heer go'an, iyo 6 calaamado isku xigxiga PWM ayaa la dooran doonaa.Tani waxay muujinaysaa xallinta shaashadda ugu badan.Haddii aad u isticmaasho serfarka shabakadda ee la cayimay meelaynta saxda ah, nidaamka bareegga tamarta-cunaya ama dib u noqoshada xoogga wadista, waxaa si xoog leh lagula talinayaa in aad isticmaasho xarunta maamulka ee buuxsan si aad isugu xigto calaamada PWM.

Si loo wanaajiyo qaybta rotor ee matoorka induction magnetka, matoorka BLDC wuxuu isticmaalaa dareeraha Saamaynta Hall-ka si uu u muujiyo meelaynta dhammaystiran ee magnetic induction.Tani waxay keenaysaa codsiyo badan iyo kharashyo badan.Inductorless BLDC Operation waxay meesha ka saartaa baahida loo qabo walxaha Hall, oo waxay doorataa oo kaliya awooda korantada ee iskeed isu keentay (xoogga korantada ee la kiciyay) ee matoorka si loo saadaaliyo loona falanqeeyo qaybta rotor ee matoorka.Hawlgalka aan dareenka lahayn ayaa si gaar ah muhiim ugu ah codsiyada nidaaminta xawaaraha jaban sida qaboojinta marawaxadaha iyo matoorada.Marka la isticmaalayo matoorada BLDC, talaajadaha iyo kombarada waa in sidoo kale lagu shaqeeyaa iyada oo aan lahayn inductors.Gelida iyo buuxinta wakhtiga buuxa ee xamuulka
Inta badan matoorada BLDC uma baahna PWM dhammaystiran, gelinta wakhtiga buuxa ama gunnada wakhtiga raritaanka oo buuxa.Waxay u badan tahay in codsiyada BLDC ee sifadan leh ay yihiin kaliya matoorada BLDC servo ee wax qabadkoodu sareeyo, matoorrada BLDC-mawjadaha sine-mowjadda dhiirigeliyay, matoorada AC caday, ama matoorada PC synchronous.

Nidaamyo kala duwan oo kala duwan ayaa loo adeegsadaa si ay u muujiyaan wax-ka-bedelka matoorada BLDC.Caadi ahaan, transistor-ka wax-soo-saarka waxaa loo isticmaalaa sidii koronto toosan oo nidaamsan si loo maareeyo tamarta shaqada ee matoorka.Habka noocaan ah ma fududa in la isticmaalo marka la wado matoor awood sare leh.Matoorada awoodda sare leh waa in ay ku shaqeyso PWM, iyo microprocessor waa in la cayimaa si uu u muujiyo bilowga iyo hawlaha xakamaynta.

Nidaamka xakamaynta waa inuu muujiyaa saddexda hawlood ee soo socda:

PWM ku shaqaynta loo isticmaalo in lagu xakameeyo xawaaraha mootada;

Nadaamka loo isticmaalo in matoorka loogu wareejiyo toosiyaha;

Adeegso xoogga koronto-dhaliyaha iskiis u shaqeysta ama element Hall si aad u saadaaliso oo aad u falanqeyso habka rotor-ka.

Isku hagaajinta ballaca garaaca wadnaha waxa kaliya loo isticmaalaa in lagu dabaqo doorsoomiyaha danab shaqaynta dabaysha matoorka.Korontada shaqada ee macquulka ah waxay si togan ula xiriirtaa wareegga waajibaadka PWM.Marka hagaajinta saxda ah ee saxda ah la helo, sifooyinka heerka qulqulka ee BLDC waxay la mid yihiin matoorada DC ee soo socda.Voltage ka shaqeeya doorsoomayaasha waxaa loo isticmaali karaa in lagu maamulo xawaaraha iyo wareegtada doorsoomiyaha matoorka.
