Kodi mfundo yogwirira ntchito ya injini ya BLDC ndi yotani?-1

Makina a brushless DC (BLDC)ndi injini yomwe imagwiritsa ntchito ukadaulo wamagetsi. Imakwaniritsa liwiro lolondola komanso kuwongolera malo kudzera pakuwongolera kolondola kwamagetsi, kupangitsa kuti brushless DC mota ikhale yabwino komanso yodalirika. Ukadaulo wosinthira pakompyutawu umathetsa kukangana kwa maburashi ndi kutayika kwamphamvu m'magalimoto amtundu wa DC, kuwalola kuti azigwira ntchito bwino. Mfundo yake yogwirira ntchito idakhazikitsidwa ndi ukadaulo wamagetsi komanso ukadaulo wamagetsi. Poyerekeza ndi ma motors amtundu wa DC, ma brushless DC motors amakwaniritsa kusintha kwamagetsi kudzera pa masensa omangidwa ndi owongolera, potero amakwaniritsa bwino kwambiri, phokoso lochepa komanso magwiridwe antchito ochepa.

Ma motors a Brushless DC nthawi zambiri amakhala ndi rotor, stator, masensa ndi controller. Rotor nthawi zambiri imapangidwa ndi maginito okhazikika, pomwe stator imakhala ndi waya. Pamene panopa akudutsa stator koyilo, maginito kwaiye kucheza ndi okhazikika maginito zakuthupi pa rotor, potero kupanga makokedwe kuyendetsa rotor kuzungulira. Masensa nthawi zambiri amagwiritsidwa ntchito kuti azindikire malo ndi liwiro la rotor kuti wolamulirayo athe kuwongolera molondola momwe akuwongolera komanso kukula kwake. Wowongolera ndi ubongo wa mota wopanda brush. Imagwiritsa ntchito chidziwitso chochokera ku sensa kuti ikwaniritse kusintha kwamagetsi, potero imayendetsa galimotoyo kuti iyende bwino.

Njira yogwirira ntchito ya motor brushless DC imatha kugawidwa m'magawo angapo: choyamba, pomwe pano ikudutsa pa koyilo ya stator, maginito opangidwa ndi maginito amalumikizana ndi maginito okhazikika pa rotor kuti apange torque kuti ayendetse kozungulira. Chachiwiri, sensa imazindikira malo ndi liwiro la rotor ndikudyetsa chidziwitso kwa wolamulira. Woyang'anira amawongolera molondola mayendedwe ndi kukula kwazomwe zikuchitika potengera chidziwitso cha mayankho kuchokera ku sensa kuti akwaniritse malo olondola komanso kuthamanga kwa rotor. Pomaliza, potengera malo ndi chidziwitso cha liwiro la rotor, wowongolerayo amawongolera molondola mayendedwe ndi kukula kwazomwe zikuchitika kuti akwaniritse kusintha kwamagetsi, potero amayendetsa mosalekeza rotor kuti azizungulira.

Poyerekeza ndi magalimoto amtundu wa DC, ma brushless DC motors ali ndi mphamvu zambiri komanso zodalirika, choncho akhala akugwiritsidwa ntchito kwambiri m'madera ambiri. M'makampani opanga magalimoto, athuSinbadbrushless DC motors amagwiritsidwa ntchito pamagalimoto amagetsi amagetsi. Kuchita kwawo moyenera komanso kodalirika kumathandizira magalimoto amagetsi kuti akwaniritse maulendo ataliatali komanso kuthamanga mwachangu. Pazida zamagetsi zapanyumba, ma motors athu a Sinbad brushless DC amagwiritsidwa ntchito pazinthu zosiyanasiyana zapakhomo, monga makina ochapira, zotsukira, ndi zina zotere. Phokoso lawo lochepa komanso kugwiritsa ntchito bwino kwambiri kumapangitsa zida zapanyumba kukhala zopulumutsa mphamvu komanso zachilengedwe. Kuphatikiza apo, ma brushless DC motors amagwiritsidwanso ntchito kwambiri m'mafakitale, ndege, ma drones ndi magawo ena.
