Kwa zaka zingapo, takhala tikuwona ma motors opanda maburashi akuyamba kulamulira zida zopanda zingwe mumakampani opanga zida.Izi ndizabwino, koma vuto lalikulu ndi chiyani?Kodi ndizofunika kwambiri bola ndikhoza kuyendetsa phula la nkhuni?um, iya.Pali kusiyana kwakukulu ndi zotsatira zake pochita ndi ma motors brushed ndi brushless motors.
Tisanalowe mu maburashi a mapazi awiri ndi ma brushless motors, tiyeni tiyambe kumvetsetsa chidziwitso cha mfundo zenizeni zogwirira ntchito za DC motors.Zikafika pakuyendetsa ma mota, zonse zimagwirizana ndi maginito.Maginito opangidwa mosiyana amakopana.Lingaliro loyambirira la mota ya DC ndikusunga magetsi ozungulira mbali yozungulira (rotor) kukopeka ndi maginito osasunthika (stator) kutsogolo kwake, potero kukoka patsogolo mosalekeza.Zili ngati kuyika Donati ya Boston Butter pandodo patsogolo panga ndikathamanga-ndidzayesa kuigwira!
Funso ndi momwe mungasungire ma donuts kusuntha.Palibe njira yosavuta yochitira izo.Zimayamba ndi maginito okhazikika (maginito osatha).Ma electromagnets amasintha mtengo (kubwerera ku polarity) pamene akuzungulira, kotero nthawi zonse pamakhala maginito okhazikika omwe ali ndi mtengo wosiyana umene ukhoza kuyenda.Kuphatikiza apo, chiwongolero chofananira chomwe chimapangidwa ndi koyilo yamagetsi pomwe chikusintha chimakankhira kutali.Tikayang'ana ma motors brushed motors ndi brushless motors, momwe ma electromagnet asinthira polarity ndiye chinsinsi.
Mu motor brushed, pali zigawo zinayi zofunika: maginito okhazikika, zida zankhondo, mphete zoyendera ndi maburashi.Maginito okhazikika amapanga kunja kwa makinawo ndipo samasuntha (stator).Imodzi imayikidwa bwino ndipo ina imakhala yolakwika, imapanga mphamvu ya maginito yosatha.
Chombocho ndi koyilo kapena ma coil angapo omwe amakhala maginito amagetsi akapatsidwa mphamvu.Ilinso ndi gawo lozungulira (rotor), lomwe nthawi zambiri limapangidwa ndi mkuwa, koma aluminiyumu ingagwiritsidwenso ntchito.
Mphete ya commutator imayikidwa pa coil ya armature muwiri (2-pole kasinthidwe), zinayi (4-pole kasinthidwe) kapena zigawo zambiri.Amazungulira ndi zida.Pomaliza, maburashi a kaboni amakhalabe m'malo ndikusamutsa mtengo kwa woyendetsa aliyense.
Chombocho chikapatsidwa mphamvu, koyilo yoyipitsidwayo imakokedwa kupita ku maginito okhazikika omwe amatsutsana.Pamene mphete ya commutator pamwamba pake imazunguliranso, imasuntha kuchoka pa kugwirizana kwa burashi imodzi ya carbon kupita ku ina.Ikafika pa burashi yotsatira, ilandila kusintha kwa polarity ndipo tsopano imakopeka ndi maginito ena okhazikika pomwe ikuthamangitsidwa ndi mtundu womwewo wa charger yamagetsi.Zowoneka, pamene commutator ifika pa burashi yolakwika, tsopano imakopeka ndi maginito abwino okhazikika.The commutator afika mu nthawi kupanga kugwirizana ndi zabwino elekitirodi burashi ndi kutsatira zoipa okhazikika maginito.Maburashi ali awiriawiri, kotero koyilo yabwino imakokera ku maginito olakwika, ndipo koyiloyo imakokera ku maginito abwino nthawi yomweyo.
Zili ngati ndine koyilo yankhondo ndikuthamangitsa Boston Butter Donut.Ndinayandikira, koma ndinasintha maganizo anga ndikutsatira zakudya zopatsa thanzi (polarity kapena chikhumbo changa chinasintha).Kupatula apo, ma donuts ali ndi zopatsa mphamvu zambiri komanso mafuta.Tsopano ndikuthamangitsa ma smoothies ndikukankhira kutali ndi kirimu cha Boston.Nditafika kumeneko, ndinazindikira kuti madonati ndi abwino kwambiri kuposa ma smoothies.Malingana ngati ndikukoka chiwombankhanga, nthawi iliyonse ndikafika ku burashi yotsatira, ndimasintha maganizo anga ndipo nthawi yomweyo ndikuthamangitsa zinthu zomwe ndimakonda mu bwalo lothamanga.Ndilo ntchito yomaliza ya ADHD.Kuphatikiza apo, pali awiri a ife kumeneko, kotero Boston Butter Donuts ndi Smoothies nthawi zonse amathamangitsidwa mwachidwi ndi m'modzi wa ife, koma mosasamala.
Mu mota yopanda maburashi, mumataya cholumikizira ndi maburashi ndikupeza chowongolera zamagetsi.Maginito okhazikika tsopano amagwira ntchito ngati rotor ndikuzungulira mkati, pomwe stator tsopano ili ndi koyilo yamagetsi yokhazikika yakunja.Wowongolera amapereka mphamvu kwa koyilo iliyonse kutengera mtengo wofunikira kuti akope maginito okhazikika.
Kuphatikiza pa kusuntha ndalama pakompyuta, wowongolera amathanso kupereka zolipiritsa zofananira pothana ndi maginito okhazikika.Popeza milandu yamtundu womwewo imatsutsana wina ndi mzake, izi zimakankhira maginito okhazikika.Tsopano rotor imayenda chifukwa cha kukoka ndi kukankhira mphamvu.
Pankhaniyi, maginito okhazikika akuyenda, ndiye tsopano ndi mnzanga wothamanga ndi ine.Sitisinthanso lingaliro la zomwe tikufuna.M'malo mwake, tinkadziwa kuti ndikufuna Boston Butter Donuts, ndipo mnzanga ankafuna smoothies.
Owongolera zamagetsi amalola kuti zosangalatsa zathu zam'mawa ziziyenda patsogolo pathu, ndipo takhala tikuchita zomwezo nthawi zonse.Wowongolera amayikanso zinthu zomwe sitikufuna kumbuyo kuti tipereke kukankha.
Ma motors a Brushed DC ndi osavuta komanso otsika mtengo kupanga zida (ngakhale mkuwa sunakhale wotsika mtengo).Popeza mota yopanda burashi imafuna cholumikizira chamagetsi, mukuyamba kupanga kompyuta mu chida chopanda zingwe.Ichi ndichifukwa chake kukwera mtengo kwa ma motors opanda brushless.
Chifukwa cha mapangidwe ake, ma motors opanda maburashi ali ndi zabwino zambiri kuposa ma motors opukutidwa.Ambiri a iwo ndi okhudzana ndi kutayika kwa maburashi ndi ma commutators.Popeza burashi iyenera kukhudzana ndi commutator kuti isamutsire ndalama, imayambitsanso kukangana.Kukangana kumachepetsa liwiro lotheka ndipo nthawi yomweyo kumatulutsa kutentha.Zili ngati kukwera njinga yokhala ndi mabuleki opepuka.Ngati miyendo yanu imagwiritsa ntchito mphamvu yomweyo, liwiro lanu lidzachepa.Mosiyana ndi zimenezo, ngati mukufuna kusunga liwiro, muyenera kupeza mphamvu zambiri kuchokera ku miyendo yanu.Mudzatenthetsanso mikombero chifukwa cha kutentha kwamphamvu.Izi zikutanthauza kuti, poyerekeza ndi ma motors opukutidwa, ma motors opanda brushless amatha kutentha pang'ono.Izi zimawapatsa mphamvu zapamwamba, choncho amasintha mphamvu zambiri zamagetsi kukhala mphamvu zamagetsi.
Maburashi a carbon nawonso amatha pakapita nthawi.Izi ndizomwe zimayambitsa zopsereza mkati mwa zida zina.Kuti chida chizigwira ntchito, burashi iyenera kusinthidwa nthawi ndi nthawi.Ma motors opanda maburashi safuna chisamaliro chotere.
Ngakhale ma motors opanda brush amafunikira olamulira amagetsi, kuphatikiza kwa rotor / stator ndikokwanira.Izi zimabweretsa mwayi wopepuka kulemera komanso kukula kocheperako.Ichi ndichifukwa chake tikuwona zida zambiri ngati driver wa Makita XDT16 wokhala ndi mapangidwe apamwamba kwambiri komanso mphamvu zamphamvu.
Zikuwoneka kuti pali kusamvetsetsana kwa ma motors opanda brushless ndi torque.Mapangidwe agalimoto opukutidwa kapena opanda burashi pawokha samawonetsa kukula kwa torque.Mwachitsanzo, makokedwe enieni a Milwaukee M18 nyundo kubowola mafuta anali ang'onoang'ono kuposa chitsanzo m'mbuyomu brushed.
Komabe, pamapeto pake wopanga adazindikira zinthu zovuta kwambiri.Zamagetsi zomwe zimagwiritsidwa ntchito m'ma motors opanda brush zimatha kupereka mphamvu zochulukirapo kwa ma mota awa zikafunika.
Popeza ma motors opanda brush tsopano amagwiritsa ntchito zida zapamwamba zamagetsi, amatha kuzindikira akayamba kutsika pansi.Malingana ngati batire ndi mota zili mkati mwanthawi ya kutentha, zida zamagetsi zamagetsi zopanda ma brushless zimatha kupempha ndikulandila zambiri zaposachedwa kuchokera pa paketi ya batri.Izi zimathandiza zida monga zobowola brushless ndi macheka kukhalabe kuthamanga kwambiri pansi katundu.Izi zimawapangitsa kukhala othamanga.Nthawi zambiri imakhala yothamanga kwambiri.Zitsanzo zina za izi ndi Milwaukee RedLink Plus, Makita LXT Advantage ndi DeWalt Perform and Protect.
Ukadaulo uwu umaphatikizira mosasunthika ma mota a chida, mabatire, ndi zamagetsi kuti zikhale zolumikizana kuti zikwaniritse magwiridwe antchito komanso nthawi yothamanga.
Kusintha - sinthani polarity ya charger - yambitsani mota yopanda maburashi ndikuyizungulira.Kenako, muyenera kuwongolera liwiro ndi torque.Liwiro limatha kuwongoleredwa posintha voteji ya BLDC motor stator.Kuwongolera ma voliyumu pafupipafupi kwambiri kumakupatsani mwayi wowongolera liwiro la mota pamlingo wokulirapo.
Kuti muwongolere makokedwe, pamene katundu wa torque wa mota akukwera pamwamba pamlingo wina, mutha kuchepetsa mphamvu ya stator.Zachidziwikire, izi zimabweretsa zofunikira zazikulu: kuyang'anira magalimoto ndi masensa.
