Chifukwa chiyani makina ochapira vacuum amafakitale amagwiritsa ntchito injini yopukutidwa kuposa injini yopanda brush?

Mota yopukutidwa, yomwe imadziwikanso kuti mota ya DC, ndi mota yamagetsi yomwe imagwiritsa ntchito maburashi ndi commutator kuti ipereke mphamvu ku rotor ya mota. Imagwira ntchito motsatira mfundo ya induction ya electromagnetic. Mu mota ya burashi, rotor imakhala ndi maginito okhazikika, ndipo stator imakhala ndi maginito amagetsi. Maburashi ndi commutator amagwiritsidwa ntchito kusintha njira ya kayendedwe ka magetsi kudzera mu maginito amagetsi, zomwe zimapangitsa kuti rotor izungulire.

Ubwino wa Brush Motors:

• Kapangidwe kosavuta komanso kolimba

• Yotsika mtengo

• Mphamvu yoyambira yapamwamba

• Mitundu yosiyanasiyana ya njira zowongolera liwiro

Zoyipa za Brush Motors:

• Zofunikira kwambiri pakukonza chifukwa cha kuvala burashi

• Moyo wochepa chifukwa cha kuvala burashi ndi commutator

• Zimapanga kutentha ndi phokoso lochuluka poyerekeza ndi ma mota opanda burashi

• Kugwiritsa ntchito bwino kochepa poyerekeza ndi ma mota opanda burashi

Mota yopanda burashi, yomwe imadziwikanso kuti mota ya BLDC (Brushless DC), ndi mota yamagetsi yomwe imagwiritsa ntchito kusintha kwamagetsi m'malo mwa maburashi ndi commutator. Imagwira ntchito motsatira mfundo ya maginito okhazikika omwe amazungulira mozungulira ma electromagnets angapo osasuntha. Kusinthaku kumachitika pogwiritsa ntchito masensa amagetsi kapena zizindikiro zobwezera kuti adziwe malo a rotor ndikuwongolera kuyenda kwa magetsi kudzera mu stator windings.

Ubwino wa Ma Brushless Motors:

• Kuchita bwino kwambiri poyerekeza ndi ma brush motors

• Moyo wautali chifukwa cha kusowa kwa maburashi ndi kuvala kwa commutator

• Zofunikira zochepa zosamalira

• Ntchito yochepetsera phokoso

• Chiŵerengero champhamvu kwambiri pakati pa kulemera ndi mphamvu

Zoyipa za Brushless Motors:

• Kapangidwe kovuta kwambiri poyerekeza ndi ma brush motors

• Mtengo wokwera woyambira

• Imafuna kulamulira kwamagetsi posintha zinthu

• Kuwongolera liwiro kochepa poyerekeza ndi mitundu ina ya ma brush motors

Zoona zake n'zakuti, makina ambiri oyeretsera ma vacuum m'mafakitale amagwiritsa ntchito ma brushed motors (omwe amadziwikanso kuti ma universal motors) m'malo mwa ma brushless motors, ngakhale kuti ma brush motor ali ndi zoletsa monga kufunikira kwakukulu kokonza chifukwa cha kuwonongeka kwa maburashi komanso moyo wautali poyerekeza ndi ma brushless motors, chifukwa chiyani?

Zifukwa zomwe zimakondera izi ndi izi:

1. Kugwiritsa Ntchito Ndalama Moyenera: Ma mota a burashi nthawi zambiri amakhala otsika mtengo popanga poyerekeza ndi ma mota opanda burashi. Ma vacuum cleaner a mafakitale nthawi zambiri amagwiritsidwa ntchito m'malo ovuta ndipo angafunike ma mota olimba omwe amatha kugwira ntchito zolemera. Ma mota a burashi amapereka njira yotsika mtengo popanda kuwononga magwiridwe antchito.
2. Mphamvu Yoyambira Kwambiri: Ma mota a burashi amapereka mphamvu yoyambira yapamwamba, yomwe ndi yothandiza kwa otsukira vacuum m'mafakitale. Mphamvu yokwera iyi imalola kuyamwa bwino komanso kuyeretsa bwino malo osiyanasiyana, kuphatikizapo makapeti, makapeti, ndi pansi m'mafakitale.
3. Malo Olamulira Liwiro: Ma mota a burashi nthawi zambiri amapereka njira yowongolera liwiro lalikulu poyerekeza ndi ma mota opanda burashi. Kusinthasintha kumeneku ndi kwabwino mu makina otsukira vacuum amafakitale chifukwa ntchito zosiyanasiyana zotsukira zingafunike liwiro losiyana la injini kuti zigwire bwino ntchito.
4. Kukula Kochepa: Ma mota a burashi nthawi zambiri amakhala opapatiza kuposa ma mota opanda burashi omwe ali ndi mphamvu yofanana. Makina otsukira a vacuum a mafakitale nthawi zambiri amafunika kukhala osavuta kusuntha komanso kunyamulika, ndipo kukula kochepa kwa ma mota a burashi kumalola mapangidwe ang'onoang'ono komanso opepuka.
5. Kupezeka: Ma mota a burashi akhala akugwiritsidwa ntchito mu zotsukira vacuum kwa nthawi yayitali ndipo amapezeka mosavuta pamsika. Opanga apanga ukadaulo wogwiritsa ntchito ndikuwongolera ukadaulo wa magalimoto a burashi kwa zotsukira vacuum zamafakitale.
