Iyo brushless DC mota ine mota muviri uye mutyairi, uye yakajairika mechatronic chigadzirwa.Nekuti iyo brushless DC mota inoshanda nenzira yekuzvidzora, haizo wedzera mhepo yekutenderera kune rotor senge inoenderana mota ine inorema inorema kutanga pasi peinosiyana frequency frequency regulation, uye haizokonzere oscillation uye kurasikirwa kwenhanho kana mutoro wachinja. pakarepo.Iwo magineti echigarire emadiki uye epakati-ekugona brushless DC mota zvino anyanya kugadzirwa zvisingawanzo pasi neodymium-iron-boron (Nd-Fe-B) zvinhu zvine akakwira magineti simba.Naizvozvo, vhoriyamu yepasi isingawanzo gineti magineti brushless mota inoderedzwa nesaizi imwe furemu kana ichienzaniswa neatatu-chikamu asynchronous mota yehumwe hukuru.
Brushed mota: Mota yakabhurwa ine brashi mudziyo, uye ndiyo mota inotenderera, iyo inogona kushandura simba remagetsi kuita magetsi emagetsi (motor), kana kushandura simba remagetsi kuita simba remagetsi (jenareta).Kusiyana nemabhurashi motors, mabhurashi maturusi anoshandiswa kusuma kana kubvisa voltage uye zvazvino.Iyo brushed mota ndiyo hwaro hwese mota.Iyo ine hunhu hwekutsanya kutanga, braking panguva, yakatsetseka yekumhanyisa kudzora mune yakakura, uye yakapusa kudzora dunhu.
Iyo inoshanda musimboti we brushed mota uye brushless mota.
1. Brushed mota
Kana mota ichishanda, coil uye commutator inotenderera, asi iyo magineti simbi uye kabhoni brashi hazvitenderere.Shanduko yekuchinja kweiyo nzira yekoiri inopedzwa nemufambi uye brashi inotenderera nemota.Muindasitiri yemotokari yemagetsi, mabhurashi mota akakamurwa kuita akakwira-kumhanya mabhurashi mota uye yakaderera-kumhanya yakabhurwa mota.Pane misiyano yakawanda pakati pemabhurashi mota uye brushless mota.Kubva pazita, zvinogona kuoneka kuti mabhurashi mota ane kabhoni mabhurashi, uye mabhurashi emagetsi haana kabhoni mabhurashi.
Iyo brashi mota ine zvikamu zviviri: stator uye rotor.Iyo stator ine magineti mapango (inotenderera mhando kana yekusingaperi magineti rudzi), uye rotor ine mamhepo.Mushure mekugadzirisa magetsi, magnetic field (magnetic pole) inoumbwawo pane rotor.Iyo inosanganisirwa kona inoita kuti mota itenderere pasi pekukwezvana kweiyo stator uye rotor magineti minda (pakati peN pole uye S pole).Nekushandura nzvimbo yebhurashi, kona iri pakati pe stator uye rotor magnetic poles inogona kuchinjwa (ichifunga kuti magnetic pole ye stator inotanga kubva pakona, iyo magnetic pole ye rotor iri kune rumwe rutivi, uye kutungamira kubva iyo magnetic pole ye rotor kune magnetic pole ye stator ndiyo nzira yekutenderera kwemotokari) nzira, nekudaro ichishandura nzira yekutenderera kwemotokari.
2. Brushless motor
Iyo brushless mota inotora yemagetsi commutation, iyo coil haifambi, uye iyo magineti pole inotenderera.Iyo brushless mota inoshandisa seti yemidziyo yemagetsi kuona chinzvimbo chegineti remagineti pole kuburikidza neHoro element.Zvinoenderana nemafungiro aya, dunhu remagetsi rinoshandiswa kushandura mafambiro echizvino mucoil nenguva kuti ive nechokwadi chekuti simba remagineti riri munzira chaiyo rinogadzirwa kutyaira mota, kubvisa kukanganisa kweiyo brashi mota.
Maseketi aya ndiwo anodzora mota.Mutongi weiyo brushless mota anogona zvakare kuona mamwe mabasa asingakwanise kubhurowa mota, sekugadzirisa magetsi ekuchinja angle, braking mota, kudzosera mota kumashure, kukiya mota, uye kushandisa brake chiratidzo kumisa magetsi kumota. .Ikozvino iyo yemagetsi alarm lock yebhatiri mota inoshandisa zvizere mabasa aya.
Mabhenefiti akasiyana e brushless mota uye brushed motors
Iyo brashi mota ine zvayakanakira, ndiko kuti, mutengo wakaderera uye kutonga kuri nyore.Mutengo wemabhurashi motors kazhinji wakakwira zvakanyanya, uye ruzivo rwehunyanzvi runodiwa mukutonga.Nekuenderera mberi kwekukura kwebrushless mota yekudzora tekinoroji, kudzikira kwemutengo wezvinhu zvemagetsi, kuvandudzwa kwevanhu zvinodiwa pamhando yechigadzirwa, uye kudzvanywa kwekuchengetedza simba uye kuderedzwa kwekubuda, akawanda uye akawanda mabhurashi mota uye AC motors zvichatsiviwa ne. DC brushless mota.
Nekuda kwekuvapo kwemabhurashi uye ma commutator, mabhurashi mota ane chimiro chakaomarara, kusavimbika kwakawanda, kutadza kwakawanda, kuremerwa kwekugadzirisa basa, hupenyu hupfupi, uye sparks dzekufamba dzinowanzo kukanganiswa nemagetsi.Iyo brushless mota haina mabhurashi, saka hapana yakabatana interface, saka yakachena, ine ruzha rushoma, chokwadi haidi kugadziridzwa, uye ine hupenyu hurefu.
Kune zvimwe zvigadzirwa zvakaderera, zvinokwanisika zvachose kushandisa brashi mota, chero bedzi ichitsiviwa nenguva.Nekudaro, kune zvimwe zvigadzirwa zvemhando yepamusoro, senge maairconditioner, mota, uye maprinta, mutengo wekutsiva Hardware wakakwira zvakanyanya, uye hauna kukodzera kugara uchitsiviwa nezvikamu, saka-hupenyu hurefu brushless DC mota dzave dzakanakisa. sarudzo.
Shenzhen Zhongling Technology Co, Ltd yanga yakatarisana nekutsvagisa kwe stepper mota uye servo mota kubva payakavambwa, uye yakawana akati wandei patents uye ine ruzivo rwakapfuma.Iyo stepper motors uye servo motors inogadzirwa nekambani zvakare inotengeswa kumba nekune dzimwe nyika, ichiva sarudzo yakanakisa kumakambani mazhinji emarobhoti uye akawanda otomatiki ekugadzira michina makambani.
