Jawaab celinta matoorka DC ee aan burushka lahayn

Tan iyo dhalashada matoor DC aan burush lahayn, Dareemka Saamaynta Hall wuxuu ahaa xoogga ugu muhiimsan ee lagu ogaanayo jawaab-celinta is-dhaafsiga. Maadaama kantaroolka saddex-waji ah uu u baahan yahay saddex dareeme oo keliya oo uu leeyahay kharash yar oo unug ah, waxay inta badan yihiin doorashada ugu dhaqaalaha badan ee ka noqoshada aragtida kharashka BOM oo keliya.Dareemayaasha saamaynta Hall ee ku dhex jira stator-ku waxay ogaadaan booska rotor-ka si transistors-ka buundada saddexda waji ah loo beddelo si ay u wadaan motor. Dareemayaasha saameyntu waxay si wax ku ool ah u xalin karaan dhibaatada socodka BLDC ee matoorka, waxay la kulmaan kaliya kala bar shuruudaha nidaamka BLDC.

In kasta oo dareemaha saamaynta Hall-ku uu awood u siinayo kontaroolaha inuu kaxeeyo mootada BLDC, koontaroolkeedu nasiib-darro wuxuu ku xaddidan yahay xawaaraha iyo jihada.Matoorka saddex-waji ah, dareeraha saamaynta Hall wuxuu bixin karaa oo kaliya booska xagal ee wareegga korantada kasta. Sida tirada lammaanaha tiirarka kor u kaca, sidaas oo kale tirada wareegyada korantada ee wareegga farsamada, iyo isticmaalka BLDCs ayaa noqda mid aad u baahsan. Si loo hubiyo in xalku adag yahay oo dhameystiran yahay, nidaamka BLDC waa inuu bixiyaa macluumaadka booska waqtiga-dhabta ah si uu maamuluhu ula socdo ma aha oo kaliya xawaaraha iyo jihada, laakiin sidoo kale masaafada safarka iyo booska xagasha.
Si loo daboolo baahida loo qabo macluumaad badan oo adag, xal caadi ah ayaa ah in lagu daro koodhadhka rotary ee kor u kaca ee matoorka BLDC. Caadi ahaan, koodhiyeyaasha kordhinta ayaa lagu daraa nidaamka xakamaynta jawaab celinta isku midka ah marka lagu daro dareenka saameynta Hall. loo isticmaalo rogida motor, halka encoders waxaa loo isticmaalaa raad dheeraad ah oo sax ah booska, wareeg, xawaaraha iyo jihada.Since dareemaha saamaynta Hall oo kaliya waxay bixisaa macluumaad booska cusub ee isbedel kasta oo gobolka Hall, ay sax ah oo kaliya gaadho lix gobol oo awood kasta cycle.For. matoorrada laba-cirifoodka ah, waxaa jira lix gobol oo kaliya halkii wareegta farsamada. Baahida labadaba waa caddahay marka la barbardhigo encoder-ka kordhinta kaas oo bixiya xallinta kumanaan PPR (pulses per kacaan), kaas oo lagu kala saari karo afar jeer tirada isbeddelada gobolka.
Si kastaba ha ahaatee, maadaama soosaarayaasha matoorada ay hadda ku qasban yihiin inay ku ururiyaan labada dareemayaal saamaynta Hall iyo koodhadhka kordhinta ee matoorada, qaar badan oo ka mid ah soosaarayaasha codeeyayaasha ayaa bilaabaya inay soo bandhigaan cod-bixiyeyaal kordhin ah oo leh wax soo saar socdaal, kuwaas oo aan caadi ahaan u tixraacno si fudud cod-bixiyeyaal. ma aha oo kaliya bixinta kanaalada orthogonal A iyo B (iyo xaaladaha qaarkood "hal mar" tusaha garaaca wadnaha Z), laakiin sidoo kale heerka U, V, iyo W calaamadaha dhaqdhaqaaqa u baahan yihiin inta badan darawallada BLDC. Tani waxay badbaadinaysaa matoorka naqshadeeye tillaabada aan loo baahnayn ee ku rakibida dareemaha saamaynta Hall iyo codeeyaha kordhinta isku mar.
Inkasta oo faa'iidooyinka habkani ay cad yihiin, waxaa jira ganacsi-offs muhiim ah. Sida kor ku xusan, booska rotor iyo stator waa in lagu hormariyaa BLDC matoor aan burush lahayn si wax ku ool ah loo kala qaado
