Summary

Brushless DC motors dzakafashama mumaindasitiri akasiyana siyana semhepo inopenga, ikava yakanyatsokodzera kusimuka nyeredzi muindasitiri yemotokari.Tinogona here kufungidzira kwakashinga - mune ramangwana, indasitiri yemotokari ichapinda mu "brushless" nguva?

Brushless DC mota hadzina mabhurashi uye macommutators, saka zita ravo.Iyo ine muviri wemota uye mutyairi, uye yakajairika mechatronic chigadzirwa.Se "mutsva" muindastiri yemota, kunyangwe nhoroondo yebrashiless DC mota dzinopinda muChina haina kureba, uye mutengo wakakwira kupfuura iwo wemamota akabhurwa, nekuda kwezvakanaka zviri pachena zvemabhurashi motors, kusimudzira kwekusimudzira kunogona kutsanangurwa se. nekukurumidza.Mushure mekupinda muChina, yakakurumidza kufarirwa nemaindasitiri akadai semidziyo yemumba, mota, ngarava nemichina, uye yakatora nzvimbo mumaindasitiri akasiyana ikasimukira nekukurumidza.

Sei mabhurashi mota aine nzvimbo?

Mutengo wakaderera pasina mubvunzo ndiwo wakatarisana nekurwiswa kweindasitiri kune brushless mota, saka nei ichigona kuramba iine nzvimbo mumusika wemota munguva pfupi?Muchokwadi, izvi zvakafanana neApple.Chero bedzi mashandisirwo ekushandisa uye mhando inogona kuvimbiswa, inogona kukwezva vatengi vakavimbika.Semuenzaniso, mutengo wezvigadzirwa zvemagetsi zveApple wakakwira kupfuura avhareji, asi musika uchiri kupisa.Zviripachena, kana mhando uye mutengo zvichigona kusarudzwa chete, vatengi vane simba rekutenga vanoramba vachiisa pamberi pemhedzisiro yekushandisa.

mukana:

(1) Brushless, kupindira kwakaderera

Iyo brashi isina mota inobvisa bhurashi, uye shanduko yakananga ndeyekuti hapana spark yemagetsi inogadzirwa kana mota yakabhurwa ichimhanya, izvo zvinoderedza zvakanyanya kukanganiswa kwemagetsi spark kune kure kure control radio.

(2) Ruzha rwakaderera uye kushanda zvakanaka

Iyo brashi isina mota haina mabhurashi, iyo friction simba inoderedzwa zvakanyanya panguva yekushanda, oparesheni inotsvedza, uye ruzha ruchave rwakaderera zvakanyanya.Iyi bhenefiti itsigiro huru yekugadzikana kweiyo modhi.

(3) Hupenyu hurefu uye mutengo wakaderera wekugadzirisa

Pasina bhurashi, kupfeka kwebrashiless mota kunonyanya kubereka.Kubva pamechanical point yekuona, iyo brushless mota ingangoita yekuchengeta-isina mota.Pazvinenge zvakakodzera, chete vanofanira kuita imwe guruva kubvisa kugadzirisa.Nokuenzanisa yapfuura uye inotevera, iwe unozoziva zvakanakira iyo brushless mota pamusoro peiyo brashi mota, asi zvese hazvisi mhedziso.Iyo brushless mota ine yakanakisa yakaderera-kumhanya torque kuita uye yakakura torque.Maitiro ekuita kweiyo brushless mota haagone kudzoserwa, asi Panyaya yekureruka kwekushandisa kwebrashiless mota, ine maitiro ekudzikisa mutengo webrashiless controllers uye kusimudzira uye kukwikwidza kwemusika kwebrushless tekinoroji kumba nekune dzimwe nyika, iyo brushless simba system ndeye. muchikamu chekukurumidza kukura uye kukurumbira, izvo zvinokurudzirawo zvikuru kukura kwekufambisa kwemuenzaniso.

kukanganisa:

(1) Iko kukwesha kukuru uye kurasikirwa kwakakura

Shamwari dzekare dzemuenzaniso dzakasangana nedambudziko iri pakutamba nemabhurashi motors munguva yakapfuura, ndiko kuti, mushure mekushandisa mota kwenguva yakati rebei, kuvhura mota kuchenesa kabhoni mabhurashi emota, inova nguva- kudya uye kushanda nesimba, uye kusimba kwekuchengetedza hakusi pasi pekuchenesa imba.

(2) Kupisa kukuru uye hupenyu hupfupi

Nekuda kwechimiro chemota yakabhurwa, kusangana kwekupokana pakati pebhurashi uye commutator yakakura kwazvo, zvichikonzera kupokana kukuru kwemota, iri nyore kugadzira kupisa, uye magineti anogara ari chinhu chinonzwa kupisa.Kana tembiricha yakakwira zvakanyanya, iyo magineti simbi ichave demagnetized., kuitira kuti kushanda kwemotokari kuderedzwa uye hupenyu hwemotokari yakasvibiswa hunokanganisa.

(3) Kushanda kwakaderera uye simba rakaderera rinobuda

Dambudziko rekupisa kwemota yakabhurowa yataurwa pamusoro inonyanya kukonzerwa nekuti ikozvino inoshanda pakupikisa kwemukati memota, saka simba remagetsi rinoshandurwa kuita simba rekupisa kusvika pamwero mukuru, saka simba rekubuda remota yakabhurwa. haisi yakakura, uye kushanda kwayo hakuna kukwirira.

Basa rema brushless motors

A brushless mota zvakare chishandiso chinoshandura simba remagetsi kuita mechanical simba.Nekushandisa simba remagetsi, simba remagetsi rinogona kuwanikwa kuti riite zvimwe zvinangwa.Chii chinoshandiswa chebrashiless mota kazhinji?Inogona kushandiswa mudiki indasitiri yemidziyo yemumba, seyakajairwa magetsi fan.Muchokwadi, iyo brushless mota inoshandura simba remagetsi kuita mechaniki simba, uye feni yemagetsi inotendeuka nekuunza iwe kunzwa kunotonhorera.Pamusoro pezvo, mucheki welawn muindasitiri yebindu anoshandisa mota isina brushless.Pamusoro pezvo, madhiri emagetsi muindasitiri yezvishandiso zvemagetsi anoshandisawo brushless mota.Basa reiyo brushless mota ndere kushandura simba remagetsi kuita remagetsi simba, kuitira kuti riite basa muhupenyu hwemunhu wese uye kugadzirisa hupenyu hwemunhu wese.

Ikozvino brushless DC mota yave kukwanisa kutsiva zvizere kumhanya kudzora kweDC mota, frequency converter + frequency conversion mota yekumhanyisa regulation, asynchronous mota + inoderedza kumhanya mutemo.Iyo inosanganisa ese mabhenefiti echinyakare DC mota uku ichibvisa kabhoni brashi uye inotsvedza mhete chimiro, uye ine yakanakisa torque maitiro.Iyo ine yakanaka torque kuita panguva yepakati uye yakaderera kumhanya, hombe yekutanga torque uye diki yekutanga ikozvino, isina nhanho yekumhanya mutemo, yakakura yekumhanyisa regulation renji, uye yakasimba yekuremedza huwandu.Zvakare, hupenyu hwazvino hweakajairwa brushed motors hunenge maawa gumi, uye hupenyu hwebrushless DC motors hwakareba kakawanda.

Uye zvakare, nekuti iyo brushless mota pachayo haina kuwedzeredza uye kabhoni bhurashi kurasikirwa, iyo yakawanda-nhanho yekudzikira kurasikirwa inobviswa, uye yakazara simba rekuchengetedza mwero inogona kusvika 20% ~ 60%, saka mutsauko wemutengo neakajairika motors unogona kuvimba chete. kuchengetedza simba.Mushure megore, mari yekutenga ichadzoserwa.Mukuwedzera, hurumende yave ichikurudzira kuchengetedza simba nekuchengetedzwa kwezvakatipoteredza mumakore achangopfuura.Brushless motors inogona kunzi ndiyo maitiro ekuvandudza mota.
