Magalimoto Opanda Brush vs Brushed: Ndi Ati Oyenera Ntchito Yanu?

Chiyambi

Mitundu iwiri yodziwika bwino ya ma DC motors ndi ma brushed motors ndi ma brushless motors (BLDC motors). Monga momwe dzinalo likusonyezera, ma brushed motors amagwiritsa ntchito maburashi kuti asinthe njira, zomwe zimathandiza kuti mota izungulire. Mosiyana ndi zimenezi, ma Brushless motors amalowa m'malo mwa makina osinthira magetsi ndi magetsi. Mitundu yonse iwiri imagwira ntchito mofanana, monga kukoka maginito ndi kupondereza maginito pakati pa coil ndi maginito okhazikika. Iliyonse ili ndi ubwino ndi kuipa kwake, komwe kungakhudze chisankho chanu kutengera zofunikira za ntchito yanu. Kumvetsetsa kusiyana pakati pa ma DC motors ndi ma DC motors opanda maginito ndikofunikira kwambiri poyesa momwe amagwirira ntchito. Chisankho chosankha mtundu umodzi kuposa wina chimadalira pazifukwa zosiyanasiyana, kuphatikizapo kugwira ntchito bwino, nthawi ya moyo komanso mtengo wake.

Zinthu zofunika kwambiri pa kusiyana pakati pa mota ya DC yopukutidwa ndi yopanda brush:

#1. Kugwiritsa Ntchito Bwino Bwino

Ma mota opanda burashi ndi ogwira ntchito bwino kuposa ma mota opangidwa ndi burashi. Amasintha mphamvu zamagetsi kukhala mphamvu yamakina molondola kwambiri, motero amachepetsa kuwononga mphamvu. Mosiyana ndi ma mota a DC opangidwa ndi burashi, ma mota opanda burashi sakumana ndi kukangana kapena kutayika kwa mphamvu komwe kumakhudzana ndi maburashi ndi ma commutator. Izi zimathandizira magwiridwe antchito, zimawonjezera nthawi yogwira ntchito, komanso zimachepetsa kugwiritsa ntchito mphamvu.

Mosiyana ndi zimenezi, ma mota opangidwa ndi brushed amaonedwa kuti ndi osagwira ntchito bwino kuposa ma mota a DC opanda brushless chifukwa cha kutayika kwa mphamvu komwe kumakhudzana ndi kukangana ndi kusamutsa mphamvu kudzera mu commutator system.

#2. Kusamalira ndi Kukhala ndi Moyo Wautali

Ma mota opanda burashiAli ndi ziwalo zochepa zosuntha ndipo alibe maulumikizidwe amakanika, zomwe zimapangitsa kuti azikhala nthawi yayitali komanso kuti asafunike kukonza. Kusowa kwa maburashi kumathetsa mavuto okhudzana ndi kusowa kwa burashi ndi mavuto ena okonza. Chifukwa chake, ma mota opanda burashi nthawi zambiri amakhala njira yotsika mtengo kwa ogwiritsa ntchito.

Kuphatikiza apo, ma mota opangidwa ndi burashi amafunika kukonzedwa kwambiri chifukwa cha kuwonongeka kwa maburashi ndi makina oyendetsera galimoto, zomwe zingayambitse kuchepa kwa magwiridwe antchito ndi mavuto a injini. Kuti maburashi agwire bwino ntchito, ayenera kusinthidwa nthawi zonse.

#3. Phokoso ndi Kugwedezeka

Mu ma mota opanda burashi, mphamvu yozungulira imatha kuyendetsedwa, zomwe zimathandiza kuchepetsa kugunda kwa mphamvu komwe kungayambitse kugwedezeka ndi phokoso la makina. Chifukwa chake, ma mota opanda burashi nthawi zambiri amapanga phokoso lochepa komanso kugwedezeka kuposa ma mota opangidwa ndi burashi. Chifukwa alibe maburashi kapena ma commutator. Kuchepetsa kugwedezeka ndi phokoso kumathandizira kuti ogwiritsa ntchito azikhala omasuka komanso amachepetsa kuwonongeka ndi kusweka akagwiritsidwa ntchito nthawi yayitali.

Mu mota ya DC yopukutidwa ndi burashi, maburashi ndi commutator amagwira ntchito limodzi ngati njira yosinthira. Motoka ikagwira ntchito, maswichi awa amatseguka ndi kutsekedwa nthawi zonse. Njirayi imalola mafunde amphamvu kuyenda kudzera mu inductive rotor windings, zomwe zimapangitsa phokoso laling'ono lamagetsi chifukwa cha kuyenda kwa magetsi kwakukulu.

#4. Mtengo ndi Kuvuta

Ma mota opanda burashi nthawi zambiri amakhala okwera mtengo komanso ovuta chifukwa cha njira yowongolera zamagetsi yosinthira. Mtengo wa ma mota opanda burashi a DC ndi wokwera poyerekeza ndiMa mota a DC opukutidwamakamaka chifukwa cha zipangizo zamakono zomwe zimagwiritsidwa ntchito popanga zinthuzi.

#5. Kapangidwe ndi Kugwira Ntchito

Ma mota a DC opanda brushless samadziyendetsa okha. Amafuna circuit yoyendetsera yomwe imagwiritsa ntchito ma transistors kuti ilamulire mphamvu yamagetsi yomwe ikuyenda kudzera mu ma coil ozungulira ma mota. Ma mota awa amagwiritsa ntchito zowongolera zamagetsi ndi ma sensor a Hall effect kuti azitha kuyendetsa mphamvu yamagetsi mu ma windings, m'malo modalira kulumikizana kwa makina.

Ma mota a DC opangidwa ndi brushed amadzisintha okha, zomwe zikutanthauza kuti safuna dalaivala kuti agwire ntchito. M'malo mwake, amagwiritsa ntchito maburashi ndi ma commutator kuti azitha kuyendetsa mphamvu zamagetsi zomwe zili mu windings, zomwe zimapangitsa kuti mphamvu ya maginito ikhalepo. Mphamvu ya maginito iyi imapanga mphamvu yamagetsi, zomwe zimapangitsa kuti injiniyo izizungulira.

#6. Mapulogalamu

Monga mtengo wama motors ogwederandipo zamagetsi zogwirizana nazo zikupitirira kuchepa, kufunikira kwa ma mota opanda maburashi ndi ma mota opangidwa ndi maburashi kukuwonjezeka. Ma mota opanda maburashi ndi otchuka kwambiri pa ma watchwatch, zida zamankhwala, zida zokongoletsa, maloboti, ndi zina zotero.

Koma pali malo omwe ma mota opangidwa ndi brushed amamveka bwino. Pali kugwiritsa ntchito kwakukulu kwa ma mota opangidwa ndi brushed m'mafoni a m'manja, ndudu zamagetsi, zowongolera masewera apakanema, zosisita maso, ndi zina zotero.
