Chifukwa Chiyani Zida Zopanda Maburashi Zikukhala Zotchuka Kwambiri?

Pamene kufunikira kwa zida zamagetsi kumawonjezeka tsiku ndi tsiku, ambiri opanga zida zamagetsi amayang'ana kwambiri kupanga zida zamagetsi zomwe zili ndi zida zapamwamba kuti zipikisane ndi mitundu yodziwika bwino. Zida zamagetsi ndiwopanda brushukadaulo ukuyamba kutchuka pakati pa DIYers, akatswiri, ndi opanga zida zamagetsi pazamalonda, zomwe sizatsopano.

Pamene chowunikira chamagetsi chokhala ndi mphamvu yosinthira alternating current (AC) kuti chiwongolere panopa (DC) chinapangidwa koyambirira kwa zaka za m'ma 1960, zida zamagetsi zokhala ndi ma motors opanda brush zidafala. Ukadaulo wozikidwa pa maginito udagwiritsidwa ntchito pazida ndi opanga zida zamagetsi; batire yamagetsi kenako idalinganiza zida zamagetsi zozikidwa ndi maginito. Ma motors opanda maburashi adapangidwa popanda kusintha kuti atumize zamakono, ndipo ambiri opanga zida zamagetsi amakonda kupanga ndi kugawa zida zokhala ndi ma motors opanda brush chifukwa amagulitsa bwino kuposa zida zopukutidwa.

Zida zamagetsi zokhala ndi ma motors opanda brush sizinakhale zotchuka mpaka zaka za m'ma 1980. Galimoto ya Brushless imatha kupanga mphamvu yofanana ndi ma motors opukutidwa chifukwa cha maginito osasunthika ndi ma transistors okwera kwambiri. Kukula kwa magalimoto opanda brush sikunayime pazaka makumi atatu zapitazi. Zotsatira zake, opanga zida zamagetsi ndi ogawa tsopano akupereka zida zodalirika zodalirika. Chifukwa chake, makasitomala amapindula ndi zabwino zazikulu monga kusiyanasiyana kwakukulu komanso kutsika mtengo wokonza chifukwa cha izi.

Maburashi ndi Brushless Motors, Pali Kusiyana Kotani? Zomwe Zimagwiritsidwa Ntchito Zambiri?

Brushed Motor

Chingwe cha motor brushed DC chimagwira ntchito ngati ma elekitiroma amitundu iwiri yokhala ndi makonzedwe a waya wamabala. The commutator, mechanical rotary switch, amasintha mayendedwe apano kawiri pa kuzungulira. Mitengo ya electromagnet imakankhira ndi kukoka maginito kuzungulira kunja kwa injini, zomwe zimapangitsa kuti magetsi azitha kudutsa mosavuta. Pamene mitengo ya commutator imadutsa mitengo ya maginito okhazikika, polarity ya electromagnet ya armature imasinthidwa.

Brushless Motor

Komano, mota yopanda burashi imakhala ndi maginito okhazikika ngati rotor yake. Imagwiritsanso ntchito magawo atatu oyendetsa ma coil komanso sensor yapamwamba kwambiri yomwe imayang'anira malo a rotor. Sensa imatumiza zidziwitso kwa wowongolera pomwe imazindikira mawonekedwe a rotor. Ma koyilowa amayendetsedwa mwadongosolo ndi wowongolera, mmodzimmodzi. Pali zabwino zina pazida zamagetsi ndiukadaulo wopanda brush, zabwino izi ndi izi:

• Chifukwa cha kusowa kwa maburashi, pamakhala ndalama zochepa zokonzekera.
• Tekinoloje ya Brushless imachita bwino pa liwiro lililonse ndi katundu wovoteledwa.
• Ukadaulo wopanda brush umawonjezera magwiridwe antchito a chida.
• Ukadaulo wa Brushless umapatsa chipangizocho zinthu zambiri zotentha kwambiri.
• Tekinoloje ya Brushless imapanga phokoso lochepa lamagetsi komanso liwiro lalikulu.

Ma motors opanda maburashi tsopano ndi otchuka kwambiri kuposa ma brushed motors. Zonsezi, kumbali inayo, zitha kugwiritsidwa ntchito m'njira zosiyanasiyana. Pazida zam'nyumba ndi magalimoto, ma brushed DC motors amagwiritsidwanso ntchito kwambiri. Adakali ndi msika wamphamvu wamalonda chifukwa cha kuthekera kosintha ma torque-to-speed ratio, omwe amapezeka kokha ndi ma motors brushed.

Sangalalani ndi Brushless Technology yokhala ndi Zida Zamphamvu Zambiri

Tiankon yagwiritsa ntchito ma motors opanda brush pazida zake zaposachedwa kwambiri za 20V, monga mitundu ina yodziwika bwino monga Metabo, Dewalt, Bosch, ndi ena. Kuti apatse ogwiritsa ntchito chisangalalo chogwiritsa ntchito zida zamagetsi zopanda mphamvu, Tiankon, monga wopanga zida zamagetsi, yatulutsa mzere wa zopukutira zazing'ono zazing'ono, zopukutira, zobowolera, zomangira, ma wrenches, nyundo zozungulira, zowulutsira, zodulira hedge, ndi zodulira udzu, zonse zimayenda pa batire imodzi. Tangoganizani kuti mutha kuchita chilichonse ndi batire limodzi: macheka, kubowola, kudula, kupukuta, ndi zina zotero. Chifukwa chokhala ndi mabatire atsopano ogwirizana, sikuti ntchito idzangowonjezereka, koma nthawi ndi malo zidzapulumutsidwanso. Chifukwa chake, mutha kulipiritsa zida zanu kamodzi ndikukwaniritsa ntchito mazanamazana ndi batri imodzi yokha yomwe imagwira ntchito ndi zida zanu zonse.

Mndandanda wa zida zopanda maburashizi umabwera ndi mabatire awiri amphamvu: batire ya 20V yokhala ndi batire ya 2.0AH Li-ion ndi batire ya 20V yokhala ndi batire ya 4.0AH Li-ion. Ngati mukufuna kugwira ntchito kwa nthawi yayitali, batire ya 20V 4.0Ah ndiyo njira yabwino kwambiri chifukwa imathandizira zida kwa nthawi yayitali. Kupanda kutero, batire ya 20V yokhala ndi batire ya 2.0Ah Li-ion ndi chisankho chanzeru ngati kuchita ndi zida sikutenga nthawi yayitali.
