PM (magnet joogto ah) matoorka ma laha garoon ku wareegaya fareemka stator-ka, taa beddelkeeda wuxuu ku tiirsan yahay PM-yada si uu u bixiyo goobta magnetic-ka ee goobta rotor-ku ay la falgasho si ay u soo saarto qulqulka. Magdhawga dabaylaha oo taxane ah oo leh cudud ayaa laga yaabaa in loo isticmaalo matoorada waaweyn si loo hagaajiyo socodka socodka. Sababtoo ah goobtani waa mid go'an, laguma hagaajin karo xakamaynta xawaaraha. Goobaha PM (stators) waxay ku habboon yihiin matoorada yaryar si loo baabi'iyo isticmaalka korantada ee garoonku. Inta badan matoorada DC ee waaweyn waa nooca "dynamo", kuwaas oo leh dabaylo istaaori ah. Taariikh ahaan, PM-yada lagama dhigi karo inay sii hayaan qulqulka sare haddii la kala diro; Dabaylaha garoonku waxay ahaayeen kuwo wax ku ool ah si loo helo qadarka qulqulka loo baahan yahay. Si kastaba ha ahaatee, PM-yada waaweyn waa kharash, iyo sidoo kale khatar ah oo ay adag tahay in la isku keeno; Tani waxay u roon tahay beeraha dhaawaca ee mishiinnada waaweyn.
Si loo yareeyo miisaanka iyo cabbirka guud, matoorada PM-ka ee yar ayaa laga yaabaa inay adeegsadaan magnet tamar sare leh oo lagu sameeyay neodymium ama walxo kale oo istaraatiijiyadeed; Inta badan kuwan oo kale waa neodymium-iron-boron alloy. Cufnaanta qulqulkooda sare, mashiinnada korantada ee leh PM-yada tamarta sare leh ayaa ugu yaraan ku tartamaya dhammaan kuwa si wanagsan loo nashqadeeyay ee isku midka ah iyo mashiinnada koronto ee soo-gelinta. Matoorada yaryar waxay u egyihiin qaabka sawirka, marka laga reebo inay haystaan ugu yaraan saddex tiir rotor (si loo hubiyo bilawga, iyada oo aan loo eegin booska rotor) iyo guriyahooda dibadda waa tuubo bir ah oo si magnetically ah ugu xirta bannaanka magnets-ka qalooca.
Qaar ka mid ah dhibaatooyinka mashiinka DC ee la bururay ayaa lagu tirtiray naqshadda BLDC. Matoorkaan, mishiinka "wareejinta wareegta" ama commutator-ka waxaa lagu badalaa shid elektaroonig ah oo dibadda ah oo la mid ah booska rotor-ka. Matoorada BLDC sida caadiga ah 85-90% hufan ama ka badan. Waxtarka mashiinka BLDC ee ilaa 96.5% ayaa la soo sheegay, halka matoorada DC ee leh burushka ay caadi ahaan 75-80% hufan yihiin.
Qaabka mawjada BLDC ee dabeecadda trapezoidal counter-electromotive Force (CEMF) waxa qayb ahaan laga soo qaatay dabaylaha istator-ka oo si siman loo qaybiyay, iyo qayb ahaan meelaynta magnets-ka joogtada ah ee rotor-ka. Sidoo kale loo yaqaan si elektaroonig ah DC ama gudaha matoorada DC, dabaylaha stator ee matoorada trapezoidal BLDC waxay noqon kartaa hal-waji, laba-waji ama saddex-weji waxayna adeegsadaan dareemayaasha saamaynta Hall ee ku rakiban dabaysha si ay u ogaadaan booska rotor iyo kharash yar oo xiran Kontoroolka loop-ka ee kontoroolka elektiroonigga ah.
Matoorada BLDC waxaa caadi ahaan loo adeegsadaa halka loo baahan yahay kontoroolka saxda ah ee xawaaraha, sida darawalada diskooga kombuyuutarka ama duubayaasha cajaladaha fiidyowga ah, xargaha CD-yada, CD-ROM (iwm.) wadisyada, iyo hababka gudaha alaabada xafiiska, sida marawaxada, daabacayaasha laysarka iyo koobiyeeyayaasha. Waxay leeyihiin faa'iidooyin dhowr ah marka loo eego matoorada caadiga ah:
Marka la barbar dhigo taageerayaasha AC ee isticmaalaya matoorada tiirarka hadhka leh, aad bay u hufan yihiin, oo aad uga qabowsan matoorada AC ee u dhigma. Hawlgalkan qabow wuxuu u horseedaa nolol aad loo wanaajiyey oo ah maraqa marawaxada.
La'aanteed la'aanteed uu duugoobi, nolosha matoorka BLDC aad ayey u dheeraan kartaa marka la barbar dhigo matoorka DC ee isticmaalaya burushyada iyo rakaabka. Isgaadhsiinta sidoo kale waxay u janjeertaa inay keento buuq badan oo koronto iyo RF ah; la'aanteed gaadiid ama burush la'aan, matoorka BLDC waxaa loo isticmaali karaa aaladaha xasaasiga ah ee korantada sida qalabka maqalka ama kombayutarada.
Dareemayaasha Saamaynta Hall ee isku midka ah ee bixiya isku-socodka ayaa sidoo kale ku siin kara calaamad tachometer ku habboon codsiyada kontoroolka-loop-ka ah (servo-controlled). Taageereyaasha, signalka tachometer-ka waxa loo isticmaali karaa in lagu soo saaro calaamada "fan OK" iyo sidoo kale in la bixiyo jawaab celinta xawaaraha orodka.
Matoorka waxaa si fudud loogula jaanqaadi karaa saacad gudaha ama dibadda ah, taasoo horseedaysa xakameynta xawaaraha saxda ah.
Matoorada BLDC ma laha fursad ay ku shidmaan, si ka duwan matoorada la cadaydo, taas oo ka dhigaysa inay ku habboon yihiin bay'ad leh kiimikooyin iyo shidaal kacsan. Sidoo kale, dhinbiilku waxa uu dhaliyaa ozone, kaas oo ku urura dhismayaal hawo liidata oo khatar u ah caafimaadka dadka degan.
Matoorada BLDC waxaa badanaa lagu isticmaalaa qalab yar sida kombiyuutarada waxaana guud ahaan loo isticmaalaa marawaxadaha si ay uga takhalusaan kulaylka aan loo baahnayn.
Sidoo kale waa matoorro aad u aamusan, taas oo faa'iido u leh haddii loo isticmaalo qalabka ay saameeyeen gariirku.
Matoorada casriga ah ee BLDC waxay ku kala duwan yihiin tamarta laga bilaabo jajab watt ilaa kiilowatts badan. Matoorada waaweyn ee BLDC ilaa qiyaastii 100 kW ayaa lagu isticmaalaa baabuurta korontada. Waxa kale oo ay ka helaan isticmaalka si weyn loogu isticmaalo dayuuradaha nooca korontada ee wax qabadkoodu sarreeyo.
Taxanaha korantada ee xamaasadda badan leh ama matoorka dhaawaca barbar socda waxaa loo tixraacaa matoor caalami ah sababtoo ah waxaa loo qaabayn karaa inuu ku shaqeeyo AC ama DC. Matoorka caalamiga ah wuxuu si fiican ugu shaqeyn karaa AC sababtoo ah hadda labadaba berrinka iyo gariirada armature-ka (oo markaa natiijada ka soo baxda magnetic) waxay beddeli doonaan (polarity roga) ee synchronism, sidaas awgeed awoodda farsamada ee ka dhalata waxay ku dhici doontaa jihada joogtada ah ee wareegga. .
Ku shaqaynta xadhkaha korontada ee caadiga ah, matoorada caalamiga ah ayaa inta badan laga helaa qiyaas ka yar 1000 watts. Matoorada caalamiga ah waxa ay sidoo kale aasaas u noqdeen matoorka soo jiidashada tareenada ee dhaqanka ee wadooyinka tareenada ee korontada ku shaqeeya. Codsigan, isticmaalka AC si loo xoojiyo matoorka asal ahaan loogu talagalay inuu ku shaqeeyo DC waxay u horseedi doontaa khasaare waxtar leh oo ay ugu wacan tahay kuleylinta hadda jirta ee qaybahooda magnetic, gaar ahaan qaybaha mashiinka beerta ee, DC, ay isticmaali lahaayeen adag ( birta aan la dahaadhayn) oo hadda aad loo isticmaalo.
