Chifukwa chiyani chotsukira chotsuka m'mafakitale chimagwiritsa ntchito mota yopukutira kuphatikiza ma mota opanda brush?

Galimoto yopukutidwa, yomwe imadziwikanso kuti DC motor, ndi mota yamagetsi yomwe imagwiritsa ntchito maburashi ndi choyendera kuti ipereke mphamvu ku rotor ya mota.Imagwira ntchito potengera mfundo ya electromagnetic induction.Mu motor burashi, rotor imakhala ndi maginito osatha, ndipo stator imakhala ndi maginito amagetsi.Maburashi ndi ma commutator amagwiritsidwa ntchito kusinthira njira yomwe ikuyenda pakalipano kudzera pamagetsi, zomwe zimapangitsa kuti rotor izungulira.

Ubwino wa Brush Motors:

• Kumanga kosavuta komanso kolimba

• Zotsika mtengo

• Torque yapamwamba kwambiri

• Kuwongolera kosiyanasiyana kwa liwiro

Kuipa kwa Brush Motors:

• Zofunikira zapamwamba zosamalira chifukwa cha kuvala burashi

• Kuchepa kwa moyo chifukwa cha burashi ndi kuvala kwa commutator

• Amatulutsa kutentha kwambiri ndi phokoso poyerekeza ndi ma motors opanda brush

• Kuchita bwino m'munsi poyerekeza ndi ma motors opanda brushless

Galimoto yopanda brush, yomwe imadziwikanso kuti BLDC (Brushless DC) motor, ndi injini yamagetsi yomwe imagwiritsa ntchito kusintha kwamagetsi m'malo mwa maburashi ndi commutator.Imagwira ntchito potengera mfundo ya maginito okhazikika omwe amazungulira mozungulira ma elekitikitimu okhazikika.Kusinthaku kumatheka pogwiritsa ntchito masensa amagetsi kapena zizindikiro zowonetsera kuti mudziwe malo a rotor ndikuwongolera kayendedwe kameneka kudzera muzitsulo za stator.

Ubwino wa Brushless Motors:

• Kuchita bwino kwambiri poyerekeza ndi ma motors a brush

• Kutalika kwa moyo chifukwa cha kusowa kwa maburashi ndi kuvala kwa commutator

• Zofunikira zochepetsera zosamalira

• Opaleshoni yabata

• Chiŵerengero chapamwamba cha mphamvu ndi kulemera

Kuipa kwa Brushless Motors:

• Zomangamanga zovuta kwambiri poyerekeza ndi ma brush motors

• Kukwera mtengo koyamba

• Pamafunika ulamuliro wamagetsi pa commutation

• Liwiro laling'ono lochepetsetsa poyerekeza ndi mitundu ina ya ma motors a brush

Zowonadi, oyeretsa ambiri m'mafakitale amagwiritsa ntchito ma brushed motors (omwe amadziwikanso kuti universal motors) m'malo mwa ma brushless motors, ngakhale mota ya burashi ili ndi malire monga zofunika pakukonza kwakukulu chifukwa cha kuvala kwa maburashi komanso moyo wamfupi poyerekeza ndi ma brushless motors, chifukwa chiyani?

Zifukwa zokonda izi ndi izi:

1. Mtengo-Kuchita bwino: Ma mota a brush nthawi zambiri amakhala otsika mtengo kupanga poyerekeza ndi ma motors opanda brush.Zotsukira zotsukira m'mafakitale nthawi zambiri zimagwiritsidwa ntchito m'malo ovuta kwambiri ndipo zimafuna ma mota amphamvu omwe amatha kugwira ntchito zolemetsa.Ma motors a Brush amapereka njira yotsika mtengo popanda kusokoneza magwiridwe antchito.
2. High Starting Torque: Ma mota a maburashi amapereka torque yayikulu, yomwe imakhala yopindulitsa kwa zotsukira zamakampani.Torque yayikuluyi imathandizira kuyamwa koyenera komanso kuyeretsa bwino malo osiyanasiyana, kuphatikiza makapeti, makapeti, ndi pansi pamafakitale.
3. Speed ​​Control Range: Ma mota a maburashi nthawi zambiri amapereka njira yowongolera liwiro poyerekeza ndi ma motors opanda brush.Kusinthasintha kumeneku ndi kopindulitsa pa zotsukira zotsukira m'mafakitale chifukwa ntchito zosiyanasiyana zotsuka zingafune kuthamanga kwa injini kuti zigwire bwino ntchito.
4. Compact Size: Ma motor maburashi nthawi zambiri amakhala ophatikizika kuposa ma motors opanda maburashi omwe ali ndi mphamvu yofanana.Zotsukira zotsukira m'mafakitale nthawi zambiri zimafunika kukhala zosunthika komanso zosunthika, ndipo kukula kophatikizika kwa ma motor maburashi kumapangitsa kuti pakhale mapangidwe ang'onoang'ono, opepuka.
5. Kupezeka: Ma mota a maburashi akhala akugwiritsidwa ntchito mu vacuum cleaners kwa nthawi yayitali ndipo amapezeka mosavuta pamsika.Opanga apanga ukadaulo wogwiritsa ntchito komanso kukhathamiritsa ukadaulo wamagalimoto aburashi kwa otsukira ma vacuum m'mafakitale.
