Ukuqaliswa kwe-brushless DC motor kwizixhobo zamandla

Ngokuphuculwa kwebhetri entsha kunye neteknoloji yolawulo lwe-elektroniki, uyilo kunye neendleko zokwenziwa kwe-brushless DC motor ziye zancitshiswa kakhulu, kunye nezixhobo ezifanelekileyo ezinokutshajwa kwakhona ezifuna i-brushless DC motor ziye zathandwa kwaye zasetyenziswa ngokubanzi. Isetyenziswa kakhulu kwimizi-mveliso yokuvelisa, ukudibanisa kunye nokugcina imveliso, ngakumbi ngophuhliso loqoqosho, imfuno yamakhaya nayo iya inyuka ngokunyuka, kwaye izinga lokukhula lonyaka liphezulu kakhulu kunelo lamanye amashishini.

2, isixhobo sombane esilungele ukutshajwa uhlobo lwesicelo semoto

2.1 Ibrashi yemoto yeDC

Ubume obuqhelekileyo be-brushless DC bubandakanya i-rotor (i-shaft, i-iron core, i-winging, i-commutator, i-bearing), i-stator (i-casing, i-magnet, i-end cap, njl.), i-carbon brush assembly, ingalo ye-carbon brush kunye nezinye iindawo.

Umgaqo osebenzayo: I-stator ye-brush ye-DC motor ifakwe kwi-pole esisigxina (umazibuthe) kunye ne-brush, kwaye i-rotor ifakwe nge-armature winding kunye ne-commutator. Amandla ombane ombane we-DC angena kwi-armature winding nge-carbon brush kunye ne-commutator, evelisa i-armature current. Intsimi yemagnethi eveliswa yi-armature yangoku inxibelelana neyona ndawo iphambili yamagnetic ukuvelisa itorque ye-electromagnetic, eyenza ukuba imoto ijikeleze kwaye iqhube umthwalo.

Izinto ezingeloncedo: Ngenxa yobukho bebrashi yekhabhoni kunye ne-commutator, ukuthembeka kwebhrashi yemoto ayilunganga, ukusilela, ukungazinzi kwangoku, ubomi obufutshane, kunye nentlantsi ye-commutator iya kuvelisa ukuphazamiseka kwe-electromagnetic.

2.2 Brushless DC motor

Ubume obuqhelekileyo be-brushless DC bubandakanya i-motor rotor (i-shaft, i-iron core, i-magnet, i-bearing), i-stator (i-casing, i-iron core, i-winging, i-sensor, i-end cover, njl. njl.) kunye namacandelo okulawula.

Umgaqo osebenzayo: I-Brushless DC motor inomzimba wemoto kunye nomqhubi, yimveliso eqhelekileyo ye-mechatronics. Umgaqo osebenzayo uyafana naleyo yemoto yebrashi, kodwa i-commutator yemveli kunye nebrashi yekhabhoni zitshintshwa yinzwa yendawo kunye nomgca wolawulo, kwaye isalathiso sangoku siguqulwa ngumyalelo wolawulo okhutshwe ngumqondiso wokuva ukuqonda umsebenzi wokuhamba, ukuze Ukuqinisekisa itorque ye-electromagnetic engaguqukiyo kunye nokuqhutywa kwemoto kunye nokwenza ukuba imotor ijikeleze.

3. Izinto eziluncedo kunye nezingeloncedo kwi-BLDC yesicelo semoto

3.1 Izinto eziluncedo ze-BLDC motor:

3.1.1 Ubume obulula kunye nomgangatho othembekileyo:

Khansela i-commutator, i-carbon brush, ingalo yebrashi kunye nezinye iindawo, akukho welding ye-commutator, inkqubo yokugqiba.

3.1.2 Ubomi obude benkonzo:

Ukusetyenziswa kwamacandelo e-elektroniki ukubuyisela ubume besiqhelo be-commutator, ukuphelisa i-motor ngenxa ye-carbon brush kunye ne-spark ye-commutator commutator, ukunxiba ngoomatshini kunye nezinye iingxaki ezibangelwa kubomi obufutshane, ubomi bemoto buyanda ngokuphindaphindiweyo.

3.1.3 Ukuzola nokusebenza kakuhle:

Akukho bhrashi yekhabhoni kunye nesakhiwo se-commutator, thintela i-spark ye-commutator kunye nokungqubuzana komatshini phakathi kwe-carbon brashi kunye ne-commutator, okukhokelela kwingxolo, ubushushu, ukulahleka kwamandla emoto, ukunciphisa ukusebenza kakuhle kwemoto. Ubunono bemoto ye-Brushless DC kwi-60 ~ 70%, kunye ne-brushless DC yemoto esebenzayo inokufezekisa i-75 ~ 90%

3.1.4 Ulawulo lwesantya esibanzi kunye namandla okulawula:

Amacandelo e-elektroniki achanekileyo kunye ne-sensors inokulawula ngokuchanekileyo isantya sokuphuma, i-torque kunye nesikhundla se-motor, ukuqonda ingqiqo kunye nemisebenzi emininzi.
