Dc garka garkaQaab dhismeedka waa macquul, xawaaraha uu asal ahaan deggan yahay, marka guud ahaan, si dhif ah loo maro sharciyo xawaare badan leh oo waxaa loo isticmaali karaa mashiinno badan, waxaa lagama maarmaan ah in lagu hagaajiyo xawaaraha iyada oo loo eegayo xawaaraha iyada oo loo eegayo xawaaraha iyada oo loo eegayo xawaaraha iyada oo loo eegayo xawaaraha iyada oo loo eegayo xawaaraha iyada oo loo eegayo munaasabadiisa. Laakiin xakameynta xamuulka ee loo yaqaan 'DC' iyo habka sharci-darrada xawaaraha ee xawaaraha ayaa u baahan qof walba inuu wax ku barto, si loogu sameeyo arji si dhakhso leh:
1. Adoo xakameynaya amarka xariga ah, xarkadda ka soo horjeedda ayaa loo qaybiyaa koox isla markaana hadda loo qaybiyaa si loo soo saaro goob magnetic ah isla jihada.
2. Tirada ulaha ee matoorka loo yaqaan 'DC-da' ee 'DC' waa saddex, si qof kasta oo ah "ulo kasta oo ah" magnetic poles "ah oo lagu gaaro si loo gaaro saameynta wareegga garoonka magnetic.under ah ee ku saabsan garoonka magnetic, rotor magnetka magnetic, Dhexnadda dhexdeeda had iyo jeer waxay leedahay u janjeera inay ku hayaan garoonka magnetic-ka isla jihada isla markaana ay ku wareegi doonto garoonka wareegga badan ee magnetic.
H1h2h3 waa seddex dareemayaal hool ah oo lagu meeleeyay farqiga hawada ee xarkaha xiisaha leh, oo loo isticmaalo shey ahaan si loo ogaado goobta magnetic. Korontada waa la beddeli karaa iyadoo loo eegayo jihada garoonka magnetic, iyo wax soo saarku waa calaamad dijital ah.
3. Xariga stator waxaa ku kordhaya si waafaqsan tahay isku xigxiga xiga, iyo meeraha Rotoru Magnetic ee Rotome Magnetic waa inuu lahaadaa xagal. ilaa gobolka shaqada ee dib ugu soo celiyay dareenka hoolka.
Amarkeedu waa in la diro saddex lammaane oo xarig ah, oo fasax ah, wareejintan waxaa lagu gaadhaa kala-guurka.
Wareegga sedex-weji BLDC-da BLDC waxaa lagu xaqiijin karaa iyadoo la xoojinayo ama goynta saddex lammaane ee kala-goys ama nidaam gaar ah.
4. Sida rotorku wareegeysa, suuragalnimada in laga soo bilaabo xidhmooyin kasta wuxuu ka baxaa ugu sarreeya ee eber iyo dib-u-soo noqoshada marka xijaradu ay horjoogsanayso korantada ka soo horjeedda, sidaa darteed qaybta mowjadda mowjarka ayaa noqon doona muuqata. isbarbar dhigga.
Maaddaama meesha eber ay ku taal bartanka Trapezoid, wareejinta BLDC waa la xakameyn karaa ka dib marka loo eego isugeynta isku xigxiga ah ka dib dib-u-dhac 30 ° .Ma u baahan tahay in loo baahdo dareenka hoolka, iyo saddex fiilooyin wadoBtlc.If the waveform is relatively ideal, the three coil voltage curves can be obtained by directly integrating the voltage.So the brushless dc motor can be controlled.
5. Go'aanso jihada bilowga ah, ka tabar jihada hoose jihadaas, samee rotor rotor u rogo booska bilowga waqti gaaban, oo ku xooji matoorka sida soo socota ee ficilada.
Si loo wanaajiyo hufnaanta isticmaalka ee 'DC' ee loo yaqaan 'DC', waxaan u baahan nahay inaan baranno sida ku xusan jawiga isticmaalka kaladuwan, xakamaynta iyo qaanuunka xawaaraha iyo habka xakameynta ee habka loo adeegsado dhaqdhaqaaqa, xakameynta xawaaraha iyo habka xawaaraha iyo habka xawaaraha ayaa loo adeegsan karaa si loo hagaajiyo xawaaraha.
