Nguva zhinji kungoerekana kwaitika uye kwakakosha kufambira mberi kunoitika munyika yezvishandiso, uye makore mashoma apfuura yaive imwe yenguva idzodzo. Inonzi brushless mota tekinoroji, uye inovimbisa kusimudzira ipapo ipapo kushanda kwetambo dzisina tambo mubhodhi. Vese vanogadzira maturusi vari kuunza maturusi asina tambo pamusika izvozvi, uye kunyangwe maturusi mazhinji asina tambo pamasherufu ezvitoro haasati aita mabhurashi, tekinoroji nyowani yakakosha kutsvaga. Kuti unzwisise chikonzero, iwe unofanirwa kunzwisisa chiibrushlessndeye zvese pamusoro pemamiriro emagetsi emagetsi. Iwe unogona kuona iwo maviri emhando dzemotor pazasi, akavhurwa zvishoma kuti aonekwe panguva yangu yekuyedza chishandiso.

Iyo Makita drill kuruboshwe ine echinyakare mabhurashi, uye Milwaukee kurudyi haina brushless. Yese mechanic kuomarara kweiyo brushed dhizaini inotsiviwa nekureruka kwemakanika kwemukati wedunhu.

Sechinyakare, magetsi emagetsi emagetsi anosanganisira madiki, echitubu-akaremerwa zvidhinha zvekabhoni zvakavigwa mukati. Aya mabhurashi anonzi mabhurashi (kunyangwe asingataridzi se "bhurashi" uye asina bristles) uye anodzvanya achipokana nechikamu chinotenderera chemota, achiendesa magetsi kwairi sezvainotendeuka, ichibatsira kugadzira nzvimbo yemagetsi inotenderera. Iyi ndiyo ndima inotenderera mukati memota inoita kuti itenderere, uye mabhurashi anga ari chikamu chakakosha chekuita kuti izvi zviitike kweanopfuura zana ramakore. Asi sekubatsira sezvavakaita, mabhurashi anoisa zvipingamupinyi zviviri zvikuru. Dzinosakara uye dzinokonzera friction.

Sezvo mabhurashi akagadzirirwa kukwesha pamativi emotokari emukati anotenderera, anosakara nekufamba kwenguva. Ndizvo zvazvinoita, uye kana mabhurashi akasatsiviwa nenguva, chero mota yechishandiso inoparara nekuenderera mberi nekushandiswa. Rimwe dambudziko remabhurashi isimba raanorasa. Kukwiza kunoreva kukwesha uye kubairira, uye izvi zvinodudzira kukushanda kushoma kunoitwa pachaji yega yega yebhatiri, zvimwe zvese zvakaenzana.

Brushless zvishandisobvisa dambudziko rekupfeka uye dambudziko rekukweshana, uye vanoita izvi nedhizaini yakapfava kupfuura yekare, madhizaini ebhurashi. Iwo marudzi maviri ezvibooreso anoratidza padivi nepadivi anoratidza mutsauko, kunyangwe iwe usingazive chero chinhu nezve motor unogona kuona mutsauko.

Chii chingave chiri nyore kupfuura ichi? Chikamu chemukati chechibooreso chisina tambo chine brushless mota chinoratidza kuti nzira iyi iri nyore sei. Hupenyu hurefu hwekushanda uye kushomeka kwemukati ndizvo zvikonzero brushless power tool motors dziri pano kuti dzigare.

Panzvimbo peiyo mechanika system yemabhurashi, zvitubu uye zvimwe zvikamu zvinoita DC yemagetsi mota kutenderera, mabhurashi maturusi anoshandisa emagetsi maseketi kuita chinhu chimwe chete nezvikamu zvishoma zvinofamba. Mhedzisiro ndezvimwe zvichemo zvakakura kubva kuvagadziri zvehupenyu hurefu hwematurusi uye basa rakawanda rinoitwa pamubhadharo. Brushless tool motors dzinofanirwa kugara dzinenge 1000% kureba kupfuura mabhurashi-style mota dzisati dzapera, uye dzinofanirwa kuendesa makumi mashanu muzana rimwe basa kubva kune rakapihwa bhatiri paki usati wachaja. Asi zvikumbiro zviri nyore kuita, ndosaka ndakafunga kuti nditarise chokwadi ini.

Kuvhura iyi DEWALT brushless drill inoratidza iri nyore mota ye brushless magetsi maturusi. Kutenderera newaya kunobva kwairi kunotora nzvimbo yema mechanical brushes uye zvitubu.

Kuedzabrushless toolkumhanya nekutsungirira, ndakaisa 18 volt Milwaukee FUEL 2604 brushless drill ine mhando imwe chete ye9/16” drill bit yandakaisa mumaviri matsva, anofananidzwa ebrashi-style madhiri: the 20 volt DeWALT DCD989 uye 18 volt Makita BHP454. Maturusi ese matatu akange achaja zvizere 3.0 amp-awa mabhatiri pakutanga kwega kwega bvunzo kumhanya. Ndakayera makomba mangani ane 10-inch akadzika maburi andaigona kuboora mumagumo ematanda akaoma emepu nechaji imwe chete, uye zvakatora nguva yakareba sei kuchera makomba aya. Ndakadzokorora bvunzo iyi kakawanda, ndichienzanisa kugadzirwa uye nhamba dzekumhanyisa kwechokwadi. Pazasi: Iyo Milwaukee brushless FUEL yakadhirowa yakamhanya 40% kureba kupfuura yakanakisa kukwikwidza mabhurasho madhiri pahukuru hwakafanana bhatiri, uye 22% nekukurumidza kupfuura inotevera yakanakisa modhi. Kuti uwane rumwe ruzivo nezve mukati mehunyanzvi misiyano pakati pebhurashi maringe nebrushless, uye kuona chaizvo madhiri matatu akaenzaniswa neimwe.

Kubudirira kwekuita kunounzwa nematurusi asina mabhurashi kunouya nekudzikisa huwandu hwesimba rakarasika nenzira yekupisa, uye kushandura simba iri pachinzvimbo kuita basa. Kunze kwemisiyano inoyerika mukumhanya uye kutsungirira, unogona zvakare kunzwa mutsauko muruoko rwako uchishandisa madhiri pasi pemutoro. Nepo kupisa kwakawanda kwaiputika kunze kwemavharo ebhurashi-maitiro ekuboora, Milwaukee yaimhanya zvinotonhorera - sezvaungatarisira.
