Mabda'a kantaroolka ee matoorka DC ee bilaa burushka ah, si uu matoorku u wareego, qaybta xakamaynta waa inay marka hore go'aamisaa booska rotor-ka matoorka sida uu qabo hoolka-sensor-ka, ka dibna go'aansado in la furo (ama xiro) awoodda ku jirta rotor sida waafaqsan dabaylaha stator. Nidaamka transistor-ka, AH, BH, CH ee rookaha (kuwa waxaa loo yaqaan transistors power cududa sare) iyo AL, BL, CL (kuwa loo yaqaan transistors power cududa hoose), ka dhigaya socodka hadda dhex mara gariiradda matoorka si isku xigta hore u soo saar (ama rogaal celis) ) waxa uu rogrogaa goobta birlabeedka oo uu la falgalaa magnets-ka rotor-ka si uu matoorku u wareego saacada/saacadaha. Marka rotor matoorku u wareego meesha uu hoolka-sensor-ku dareemo koox kale oo calaamado ah, unugga kantaroolku wuxuu daaraa kooxda soo socota ee transistor-ka awoodda, si matoorka wareega ahi uu u sii wadi karo inuu u wareego isla jihada ilaa qaybta xakamaynta ay go'aansato dami korontada haddii uu matoorku istaago. transistor (ama kaliya shid transistor-ka gacanta hoose); Haddii rotor-ka matoorka la rogmanayo, isku xigxiga transistor-ka korontadu waa la rogayaa. Asal ahaan, habka furitaanka ee transistor-ka korontadu wuxuu noqon karaa sida soo socota: AH, BL group → AH, CL group → BH, CL group → BH, AL group → CH, AL group → CH, BL group, laakiin waa inaysan u furmin sida AH AL ama BH, BL ama CH, CL. Intaa waxaa dheer, sababtoo ah qaybaha elektarooniga ah waxay had iyo jeer leeyihiin wakhtiga jawaabta ee furaha, wakhtiga jawaabta transistor-ka korontada waa in la tixgeliyaa marka transistor-ka korontada la damiyo. Haddii kale, marka gacanta sare (ama cududda hoose) aan si buuxda loo xirin, cududda hoose (ama cududda sare) ayaa mar hore shidday, natiijada, gacmaha sare iyo hoose waa gaaban gaaban iyo transistor-ka korontada ayaa gubanaya. Marka uu matoorku wareego, qaybta koontaroolku waxay is barbardhigi doontaa amarka (Command) oo ka kooban xawaaraha uu dejiyay darawalku iyo xawaaraha dardargelinta/deceleration iyo xawaaraha isbeddelka signalada hoolka-sensor (ama lagu xisaabiyo software), ka dibna go'aamin doona kooxda soo socota ( AH, BL ama AH, CL ama BH, CL ama ...) shido waa la shidayaa, iyo inta ay shidmaan. Xawaaruhu hadduu ku filnaan waayo wuu dheeraanayaa, haddii uu xawaarihiisu aad u sarreeyona waa la soo gaabin doonaa. Qaybtan shaqada waxaa qabta PWM. PWM waa habka lagu go'aamiyo in xawaaraha matoorku uu yahay mid degdeg ah ama gaabis ah. Sida loo dhaliyo PWM noocan oo kale ah ayaa ah udub dhexaadka lagu gaadho xakamaynta xawaaraha saxda ah. Xakamaynta xawaaraha sare ee xawaaraha wareega waa in ay tixgelisaa in xallinta CLOCK ee nidaamka ay ku filan tahay in la fahmo wakhtiga lagu shaqeynayo tilmaamaha software. Intaa waxaa dheer, habka helitaanka xogta ee isbeddelka calaamadda hall-sensor waxay sidoo kale saameynaysaa waxqabadka processor-ka iyo saxnaanta xukunka. waqtiga dhabta ah. Xagga xakamaynta xawaaraha-hoose, gaar ahaan bilawga xawaaraha-hoose, beddelka signalka-sensor-ka ee soo laabtay ayaa noqda mid gaabis ah. Sida loo qabto calaamadda, habka waqtiga, iyo habaynta qiyamka halbeegyada kantaroolka si habboon iyadoo loo eegayo sifooyinka matoorka ayaa aad muhiim u ah. Ama isbeddelka soo celinta xawaaraha wuxuu ku salaysan yahay isbeddelka codeeyaha, si xallinta calaamaduhu loo kordhiyo si loo kantaroolo wanaagsan. Matoorku si habsami leh ayuu u shaqayn karaa oo si fiican ayuu uga jawaabi karaa, ku habboonaanta xakamaynta PID-da lama iska indho tiri karo. Sidii hore loo soo sheegay, mashiinka DC-ga ee aan burushka lahayn waa kantaroolka xiran, markaa calaamadda jawaab-celinta waxay u dhigantaa in la sheego unugga kantaroolka inta uu xawaaraha matoorku ka fog yahay xawaaraha bartilmaameedka, taas oo ah qaladka (Error). Ogaanshaha qaladka, waa lagama maarmaan in si dabiici ah loo magdhabo, habkuna wuxuu leeyahay kantaroolka injineernimada dhaqameed sida kantaroolka PID. Si kastaba ha ahaatee, gobolka iyo deegaanka xakamaynta dhab ahaantii waa mid adag oo la beddeli karo. Haddii xakameyntu ay tahay mid adag oo waara, arrimaha la tixgelinayo waxaa laga yaabaa inaan si buuxda loo fahmin kantaroolka injineernimada dhaqameed, sidaas darteed koontaroolka wareerka ah, nidaamka khabiirada iyo shabakada neerfaha ayaa sidoo kale lagu dari doonaa aragti caqli gal ah oo muhiim ah oo ku saabsan xakamaynta PID.
