1. Kusiyana kwa mfundo: mota ya burashi imatengera kusintha kwamakina, mtengo wa maginito susuntha, cfuel imazungulira. Pamene galimoto ikugwira ntchito, cfuel ndi commutator zimazungulira, maginito ndi burashi ya carbon sizizungulira, ndipo kusintha kosinthika kwa cfuel komweko kumatheka ndi commutator ndi burashi yomwe imazungulira ndi galimoto. Brushless motor imatengera kusintha kwamagetsi, cfuel sisuntha ndipo maginito amazungulira.
2. Kusiyana kwa kayendetsedwe ka kayendetsedwe ka liwiro: Ndipotu, ma motors onse amayendetsedwa ndi kayendetsedwe ka magetsi, chifukwa chakuti brushless DC imagwiritsa ntchito kusintha kwamagetsi, kuyendetsa digito kumafunika. Brushless DC imasinthidwa ndi burashi ya kaboni, ndipo imatha kuwongoleredwa ndi mabwalo amtundu waanalogi monga silicon controlled, yomwe ndi yosavuta.
Kusiyana kwamachitidwe:
▶ 1. Makina opangira burashi ali ndi mawonekedwe osavuta, nthawi yayitali yachitukuko komanso ukadaulo wokhwima.
Kumayambiriro kwa kubadwa kwa injini m'zaka za zana la khumi ndi zisanu ndi zinayi, injini yothandiza yomwe idapangidwa inali yopanda mawonekedwe, mwachitsanzo, AC squirrel-cage asynchronous motor, yomwe yakhala ikugwiritsidwa ntchito kwambiri kuyambira kubadwa kwa AC. Komabe, pali zolakwika zambiri zosagonjetseka zamagalimoto asynchronous, kotero kuti chitukuko chaukadaulo wamagalimoto chikuchedwa.
▶ 2. DC brush motor ili ndi liwiro loyankhira mwachangu komanso torque yayikulu:
DC brush motor imayankhira mwachangu, torque yayikulu yoyambira, kusintha kwa liwiro losalala, ndipo sikumamva kugwedezeka kuchokera ku zero kupita ku liwiro lalikulu. Ikhoza kuyendetsa katundu wokulirapo poyambira. Brushless motor imakhala ndi kukana kwakukulu koyambira (inductance), motero imakhala ndi mphamvu yaying'ono, torque yaying'ono yoyambira, kung'ung'udza poyambira, kutsagana ndi kugwedezeka kwamphamvu, kuyendetsa pang'ono poyambira.
▶ 3. DC brush motor imayenda bwino ndikuyamba bwino komanso mabuleki:
Ma motor maburashi amayendetsedwa ndi voteji, motero yambani ndikuphwanya bwino ndikuthamanga bwino pafupipafupi. Ma motors opanda brush nthawi zambiri amayendetsedwa ndi kutembenuka kwa digito. Choyamba AC imasinthidwa kukhala DC, kenako DC kukhala AC. Kuthamanga kumayendetsedwa ndi kusintha kwafupipafupi. Chifukwa chake, ma motors opanda maburashi amathamanga mosagwirizana poyambira ndi kugwetsa, ndikugwedezeka kwakukulu, ndipo pokhapokha ngati liwiro limakhala lokhazikika, amathamanga bwino.
▶ 4. Kuwongolera kwakukulu kwa DC brush motor:
DC brush motor nthawi zambiri imagwiritsidwa ntchito limodzi ndi gearbox ndi decoder, zomwe zimapangitsa mphamvu yotulutsa mota kukhala yayikulu ndikuwongolera kulondola. Kuwongolera kulondola kumatha kufika 0.01 mm, ndipo kumatha kusiya magawo osuntha pafupifupi kulikonse komwe mungafune. Zida zonse zamakina olondola zimagwiritsa ntchito mota ya DC kuwongolera kulondola.
▶ 5. DC brush motor ili ndi mtengo wotsika komanso kukonza kosavuta.
Chifukwa cha mawonekedwe ake osavuta, mtengo wotsika wopanga, opanga ambiri ndiukadaulo wokhwima, DC burashi mota imagwiritsidwa ntchito kwambiri komanso yotsika mtengo kwambiri. Ukadaulo wamagalimoto a Brushless ndiwachibwana, mtengo wake ndi wokwera komanso mawonekedwe ogwiritsira ntchito ndi ochepa. Iyenera kugwiritsidwa ntchito makamaka pazida zothamanga nthawi zonse, monga ma air conditioner osiyanasiyana, firiji, ndi zina zotero. Kuwonongeka kwa galimoto kwa Brushless kungasinthidwe kokha.
▶ 6. Mopanda burashi, kusokoneza pang'ono:
Galimoto yopanda maburashi imachotsa maburashi ndipo kusintha kwachindunji ndiko kusowa kwazitsulo zamagetsi zomwe zimapangidwira pamene brushless motor ikuyenda, zomwe zimachepetsa kwambiri kusokoneza kwa magetsi a magetsi pazida za wailesi yakutali.
