Munyaya yeinjiniya yemagetsi, mota dzemagetsi dzinoshanda nesimba (DC) dzinoita basa guru mumabasa akasiyana-siyana. Pakati pemota dzeDC, idzo dzine mabhurashi dzinoshandiswa zvakanyanya. Zvisinei, zvinoita sekunge pane kuvhiringidzika maererano nemota dzeDC dzine mabhurashi ecarbon nemota dzeDC dzine mabhurashi. Muchinyorwa chino, tichaongorora mutsauko uripo pakati padzo uye toongorora mamiriro adzo ekushandiswa.
Kujekesa Mashoko
Chekutanga, zvakakosha kuziva kuti mota dzeDC dzemabhurashi ecarbon brush chaizvoizvo iboka remabhurashi eDC. Izwi rekuti "mota yebrush DC" rinonyanya kutsanangurwa, nepo "mota yeDC yebrush brush" richireva mota yeDC yebrush uko mabhurashi akagadzirwa nezvinhu zvakagadzirwa necarbon.
Kusiyana Kwemaumbirwo Nezvinhu
Zvinhu zvebhurashi
- Mota dzeDC dzeCarbon Brush: Sezvinoreva zita racho, mabhurashi ari mumamota aya anonyanya kugadzirwa nekabhoni. Kabhoni ine hunhu hwakanaka hwekuzvizora, izvo zvinoderedza kukweshana pakati pebhurashi necommutator. Izvi zvinoita kuti bhurashi isaparare zvakanyanya, zvichiita kuti hupenyu hwebhurashi hurambe huchireba. Pamusoro pezvo, kabhoni inyanzvi yemagetsi yakanaka, kunyange hazvo conductivity yayo isiri yakakwira sedzimwe simbi. Semuenzaniso, mumamota madiki anofarira zvekushandisa, mabhurashi ekabhoni anowanzo shandiswa nekuda kwemutengo wawo uye kuvimbika kwawo.
- Brush DC Motors (mupfungwa yakafara): Mabhurashi ari mumamota eDC asina kabhoni anogona kugadzirwa nezvinhu zvakasiyana-siyana. Semuenzaniso, mabhurashi esimbi negrafiti anobatanidza simba remagetsi resimbi (senge mhangura) nehunyanzvi hwegirafiti hunozvizora uye hunodzivirira kupera. Mabhurashi aya anowanzo shandiswa mukushandiswa uko simba remagetsi rakawanda rinodiwa.
Kudyidzana kweVashandi
- Mota dzeDC dzeCarbon Brush: Mabhurashi ekabhoni anotsvedza zvakanaka pamusoro penzvimbo yemagetsi. Kuzvizora kwekabhoni kunobatsira kuchengetedza simba rekubatana rakasimba, izvo zvakakosha pakubatana kwemagetsi kwakasimba. Mune zvimwe zviitiko, mabhurashi ekabhoni anogonawo kuburitsa ruzha rushoma rwemagetsi panguva yekushanda, zvichiita kuti akwanise kushandiswa anonzwa kukanganiswa kwemagetsi.
- Bhurasha DC Motors nemabhurashi akasiyana: Mabhurashi esimbi - graphite, nekuda kwehunhu hwawo hwakasiyana hwemuviri, angada dhizaini yakasiyana yecommutator. Kufambiswa kwepamusoro kwechikamu chesimbi kunogona kutungamira kune mapatani akasiyana ekugoverwa kwemagetsi pamusoro pecommutator, uye nekudaro, commutator ingangoda kugadzirwa kuti ishande izvi zvinobudirira.
Kusiyana Kwekushanda
Simba uye Kushanda Zvakanaka
- Mota dzeDC dzeCarbon Brush: Kazhinji, mota dzeDC dzemabhurashi ecarbon brush dzakanyatsokodzera kushandiswa kwesimba rakaderera kusvika pakati nepakati. Kufambiswa kwadzo kwemhepo kwakaderera zvichienzaniswa nedzimwe bhurashi dzesimbi kunogona kukonzera kusasimba kwemagetsi kwakanyanya, izvo zvinogona kutungamira mukurasikirwa kwesimba muchimiro chekupisa. Zvisinei, hunhu hwadzo hwekuzvizora hunoderedza kurasikirwa kwemagetsi nekuda kwekukweshana, izvo zvinobatsira kuchengetedza kushanda zvakanaka. Semuenzaniso, mumidziyo midiki yemumba senge mafeni emagetsi, mota dzeDC dzemabhurashi ecarbon brush dzinoshandiswa zvakanyanya, dzichipa simba rakakwana ukuwo simba richiri kushanda zvakanaka zvakakwana kushandiswa mumba.
- Bhurasha DC Motors nemabhurashi akasiyana: Mota dzine mabhurashi esimbi - graphite dzinowanzo shandiswa mukushandisa simba guru. Kufambiswa kwemagetsi kwakanyanya kwechikamu chesimbi kunobvumira kutamiswa kwakanaka kwemagetsi akawanda, zvichikonzera simba rakawanda rekubuda. Michina yemaindasitiri, yakadai semasisitimu makuru ekutakura zvinhu, inowanzo shandisa mhando idzi dzemota kutyaira zvinhu zvinorema.
Kudzora Kumhanya
- Mota dzeDC dzeCarbon Brush: Kudzora kumhanya kwemamota eDC ecarbon brush kunogona kuitwa nenzira dzakasiyana-siyana, dzakadai sekugadzirisa voltage yekupinda. Zvisinei, nekuda kwehunhu hwawo, anogona kusapa mwero wakafanana wekudzora kumhanya kwakarurama semamwe marudzi emamota. Mumashandisirwo apo kugadzikana kwekumhanya hakusi kwakakosha zvakanyanya, semune mamwe mafeni ekufema ari nyore, mamota eDC ecarbon brush anogona kushanda zvakanaka.
- Bhurasha DC Motors nemabhurashi akasiyana: Mune zvimwe zviitiko, kunyanya nezvinhu zvemabhurashi uye magadzirirwo emhando yepamusoro, kudzora kumhanya kuri nani kunogona kuwanikwa. Kukwanisa kubata magetsi akakwira uye kubatana kwemagetsi kwakasimba kunogona kugonesa matekiniki ekudzora kumhanya kwakanyanya, akadai sekushandisa pulse - width modulation (PWM) zvinobudirira. Mamota eservo ane simba repamusoro, anoda kudzora kumhanya kwakanyatsojeka kumashandisirwo akaita serobhoti, anogona kushandisa mabhurashi ane zvinhu zvakakosha pachinangwa ichi.
Maitiro Ekushandisa
Mota dzeDC dzeCarbon Brush
- Zvigadzirwa zvemagetsi zvevatengi: Dzinoshandiswa zvakanyanya mumidziyo midiki yemagetsi yakadai semabhurashi emagetsi, mahair dryer, uye mafeni anotakurika. Hukuru hwadzo hudiki, mutengo wakaderera, uye mashandiro akakwana zvinogutsa zvinodiwa nemidziyo iyi.
- Zvishongedzo zveMotokari: Mumota, mota dzeDC dzemabhurashi ecarbon dzinoshandiswa muzvinhu zvakaita semawipers ewindshield, mahwindo emagetsi, uye ma adjuster ezvigaro. Mamota aya anofanira kuva akavimbika uye asingadhuri, uye mota dzeDC dzemabhurashi ecarbon dzinokwana.
Bhurasha DC Motorsnemabhurashi akasiyana
- Michina yeMaindasitiriSezvambotaurwa, munzvimbo dzemaindasitiri, mota dzine mabhurashi anofambisa mhepo zvakanyanya dzinoshandiswa kutyaira michina mikuru. Mufekitori yekugadzira, mota dzinoshandisa mapombi ane simba guru, macompressor, uye michina yekugaya dzinowanzoda simba guru rekubudisa uye kudzora kwakaringana, izvo zvinogona kupihwa nemabhurashi DC motors ane zvinhu zvebhurashi zvakakodzera.
- Ndege neDziviriro: Mune mamwe mashandisirwo emuchadenga, akadai seactuators dzendege, mamota eDC emabhurashi ane mabhurashi akasarudzika anoshandiswa. Mamota aya anofanira kushanda mumamiriro ezvinhu akaoma, kusanganisira tembiricha yakakwira uye nzvimbo dzinodedera zvakanyanya. Kusarudzwa kwebhurashi kwakakosha kuti uve nechokwadi chekuti inoshanda zvakanaka mumamiriro ezvinhu akaoma kudaro.
Mukupedzisa, kunyange hazvo mota dzeDC dzemabhurashi ecarbon dziri mhando yemota yeDC yebrush, musiyano wezvinhu zvemabhurashi uye hunhu hwekushanda hunokonzera mamiriro akasiyana ekushandiswa. Kunzwisisa misiyano iyi kwakakosha kune mainjiniya nevagadziri pakusarudza mota yeDC yakakodzera pane imwe application.
