Algorithms kontoroolka mootada caadiga ah ee BLDC matoorada DC aan burushka lahayn

Matoorada DC-ga ee aan cadaysnayn waa kuwo iskood isu-wareegaya (is beddelka jihaynta), markaa way ka adag yihiin in la xakameeyo.
Xakamaynta matoorka BLDC waxay u baahan tahay fahamka booska rotor-ka iyo habka loogu talagalay hagaajinta iyo hagidda mootada awood.
Matoor yar oo DC ah oo aan burush lahaynMatoorada waxay isticmaali karaan calaamadaha PWM gees-ama dhex-dhexaadka ah iyadoo loo eegayo shuruudaha codsiga. Codsiyada badankoodu waxay u baahan yihiin oo kaliya hawlgallo xawaare-kala duwan waxayna isticmaali doonaan lix geesood oo madax-bannaan oo calaamadda PWM ah. Tani waxay siinaysaa xalka ugu sarreeya ee suurtogalka ah. Haddii codsigu u baahan yahay meelaynta server-ka biriiga korantada, ama rogida korantada, isticmaalka calaamada PWM ee isku xidha dhex-dhexaadka ah ayaa lagu talinayaa.
Si loo dareemo booska rotor, BLDC waxay qabataa dareeraha saameynta Hall si ay u bixiso booska saxda ah ee induction. Tani waxay keenaysaa isticmaalka khadadka badan iyo kharashyada sare. Xakamaynta BLDC ee aan lahayn Sensor-ka ayaa meesha ka saaraysa baahida loo qabo dareeraha Hall oo beddelkeeda waxay isticmaashaa xoogga korontada ee dambe (EMF). ) ee matoorka si loo saadaaliyo booska rotor. Xakamaynta dareemedu waxay lagama maarmaan u tahay codsiyada xawaaraha kala duwan ee qiimaha jaban sida marawaxadaha iyo bambooyinka. Isticmaalka mashiinka BLDC, qaboojiyaha iyo qaboojiyaha hawada ayaa sidoo kale u baahan xakameyn aan dareemeyn.
Gelida iyo buuxinta wakhtiga wax rarista ah
Inta badan matoorada BLDC uma baahna PWM dhameystiran, gelinta waqti-la'aan, ama magdhow waqti-la'aan ah. Codsiyada BLDC kaliya ee u baahan kara sifooyinkan ayaa ah waxqabadka sare ee BLDC servo matoorada, matoorrada BLDC-da ee xiisaha leh, AC buraash la'aan, ama PC synchronous matoorada
Xakamaynta algorithm
Inta badan algorithms kantaroolka kala duwan ayaa loo isticmaalaa si ay u bixiyaan kantaroolka matoorada BLDC. Caadi ahaan, transistor-yada korontada waxaa loo isticmaalaa sidii nidaamiye toos ah si loo xakameeyo voltada mootada. Habkani maaha mid wax ku ool ah marka la wado matoorada awoodda sare leh. bixiyaan hawlaha bilowga iyo xakamaynta.
