Kuenzanisa kwakadzama pakati pemota ye micro stepper nemota yeN20 DC: nguva yekusarudza torque uye nguva yekusarudza mutengo?

Mukugadzira michina chaiyo, sarudzo yesimba inowanzo sarudza kubudirira kana kukundikana kweprojekiti yese. Kana nzvimbo yekugadzira iri shoma uye sarudzo ichida kuitwa pakati pema micro stepper motors nema N20 DC motors aripo, mainjiniya mazhinji nevatariri vekutenga vachave vachifunga zvakadzama: vanofanira here kutevera kudzora kwakanyatsojeka uye torque yakakwira yema stepper motors, kana kusarudza mukana wemutengo uye kudzora nyore kwema DC motors? Uyu hausi mubvunzo wehunyanzvi wekusarudza akawanda chete, asiwo sarudzo yehupfumi ine chekuita nebhizinesi reprojekiti.

I、 Pfupiso Yezvinhu Zvikuru: Nzira Mbiri Dzakasiyana dzeUnyanzvi

Mota ye micro stepper:mambo wekutonga kwakajeka kwe open-loop

Musimboti wekushanda:Kuburikidza nekudzora kwepulse yedhijitari, kutenderera kwepulse kwega kwega kunoenderana nekutama kwakatarwa kwekona

Zvakanakira zvepakati:nzvimbo chaiyo, torque yakakwirira, kugadzikana kwakanaka kwekumhanya kwakaderera

Maitiro akajairika:Maprinta e3D, zviridzwa zvakanyatsonaka, majoini erobhoti, michina yekurapa

N20 DC Mota: Mhinduro Yekushandisa Mari Nekukurumidza

Musimboti wekushanda: Kudzora kumhanya uye torque kuburikidza nevoltage uye current

Zvakanakira zvepakati: mutengo wakaderera, kutonga kuri nyore, kumhanya kwakafara, kushanda nesimba kwakanyanya

Maitiro akajairika: mapombi madiki, masisitimu ekukiya magonhi, mhando dzematoyi, mafeni ekufema

II、 Kuenzanisa Kwakadzika Kwezvikamu Zvisere: Data Rinozivisa Chokwadi

1. Kurongeka kwenzvimbo: musiyano uripo pakati pedanho remamirimita nedanho redanho

Mota ye micro stepper:nekona yedanho yakajairika ye1.8 °, inogona kusvika pa51200 subdivision/rotation kuburikidza ne micro stepper drive, uye kunyatsorongeka kwenzvimbo kunogona kusvika ± 0.09 °

Mota yeDC N20: hapana basa rekuisa nzvimbo rakavakirwa mukati, rinoda encoder kuti iwane kutonga kwenzvimbo, encoder inowedzera inowanzopa 12-48CPR

Kunzwisisa kweinjiniya: Mumamiriro ezvinhu anoda kudzora nzvimbo yakakwana, mota dze stepper isarudzo yechisikigo; Kune mashandisirwo anoda kudzora kumhanya kwakanyanya, mota dzeDC dzinogona kunge dzakakodzera.

2. Hunhu hweTorque: Chengetedza mutambo pakati petorque ne torque curve yekumhanya

Mota ye micro stepper:ine torque yakanaka kwazvo yekubata (yakadai semota yeNEMA 8 inosvika 0.15N · m), torque yakagadzikana pamhanya wakaderera

Mota yeDC N20:torque inoderera nekumhanya kuri kuwedzera, kumhanya kwakanyanya kusina mutoro asi torque yerotor yakakiyiwa yakaganhurirwa

Tafura Yekuenzanisa yeData Rechokwadi Rekuyedza:

3. Kuomarara kwekudzora: musiyano wehunyanzvi pakati pekurova kwemoyo vs. PWM

Kudzora mota yestepper:inoda mutyairi wematanho akazvipira kuti ape zviratidzo zvekurova kwemoyo uye zvekutungamirira

Kudzora mota yeDC:Dunhu reH-bridge riri nyore rinogona kutenderera mberi nekudzokera shure uye kudzora kumhanya

4. Kuongorora Mutengo: Kufungisisa kubva paMutengo weChikamu kusvika paMutengo weSisitimu Yese

Mutengo wemota: Mota yeN20 DC inowanzova nemutengo wakakosha (inotengwa nemutengo wakawanda inosvika madhora ekuAmerica 1-3)

Mutengo wose wehurongwa: Sisitimu yemota yestepper inoda madhiraivha ekuwedzera, asi sisitimu yeDC motor positioning inoda ma encoders uye vanodzora vakanyanya kuomarara.

Maonero ekutenga: Mapurojekiti madiki ekutsvaga nekugadzira anogona kunyanya kutarisa mutengo weyuniti, nepo mapurojekiti ekugadzira akawanda achifanira kuverenga mutengo wese wesystem.

III、 Gwaro Rekusarudza: Kusarudzwa Kwakarurama Kwezviitiko Zvishanu Zvekushandisa

Muenzaniso 1: Mashandisirwo anoda kutonga kwakarurama kwenzvimbo

Sarudzo inokurudzirwa:Mota ye micro stepper

Chikonzero:Kudzora kwe loop yakavhurika kunogona kuwana nzvimbo chaiyo pasina chikonzero chemaitiro akaomarara emhinduro

Muenzaniso:Kufamba kwemusoro wekudhinda we3D printer, nzvimbo chaiyo yepuratifomu yemaikorosikopu

Chiitiko chechipiri: Kugadzirwa kwakawanda kunonyanya kudhura zvakanyanya

Sarudzo inokurudzirwa:Mota yeDC N20

Chikonzero:Deredza zvakanyanya mari yeBOM uku uchivimbisa mashandiro ekutanga

Muenzaniso: Kudzora mavharuvhu emidziyo yepamba, dhiraivha yematoyi inodhura zvishoma

Muenzaniso wechitatu: Mashandisirwo ekutakura zvinhu zvishoma ane nzvimbo shoma kwazvo

Sarudzo inokurudzirwa: Mota yeN20 DC (ine bhokisi regiya)

Chikonzero: Saizi diki, zvichipa simba rinonzwisisika remagetsi munzvimbo shoma

Muenzaniso: kugadziriswa kwegimbal yedrone, majoini madiki emunwe werobhoti

Muenzaniso wechina: Mashandisirwo akatwasuka anoda kuti torque ibatike zvakanyanya

Sarudzo inokurudzirwa:Mota ye micro stepper

Chikonzero: Inogona kuramba iri panzvimbo yayo mushure mekunge magetsi adzima, hapana mudziyo wekubata mabhureki unodiwa

Muenzaniso:Kamuchina kadiki kekusimudza, kugadzirisa kona yekamera

Muenzaniso wechishanu: Mashandisirwo anoda kumhanya kwakakura

Sarudzo inokurudzirwa: Mota yeDC N20

Chikonzero: PWM inogona kuzadzisa zviri nyore mutemo mukuru wekumhanya

Muenzaniso: Kudzora kuyerera kwemapombi madiki, kudzora kumhanya kwemhepo kwemidziyo yekufema

IV、 Mhinduro yehybrid: kuputsa pfungwa dzebinary

Mune mamwe mashandisirwo epamusoro-soro, musanganiswa wematekinoroji maviri unogona kufungwa nezvawo:

Kufamba kukuru kunoshandisa mota yestepper kuti ive nechokwadi chekuti

Mashandiro ekubatsira anoshandisa mota dzeDC kudzora mitengo

Kudzika kwechiuno chakavharwa kunopa mhinduro yekubvumirana mumamiriro ezvinhu apo kuvimbika kunodiwa

Nyaya yekuvandudza: Mukugadzira muchina wekofi wemhando yepamusoro, mota inokwira inoshandiswa kuona kuti inomira panzvimbo chaiyo yekusimudza musoro wekubikira, ukuwo mota yeDC inoshandiswa kudzora mitengo yepombi yemvura negrinder.

V、 Mafambiro Emangwana: Kuchinja Kunoita Kubudirira Kwetekinoroji Sarudzo

Kushanduka kwetekinoroji yemota yestepper:

Dhizaini yesystem yakareruka yemota yestepper yakangwara ine mutyairi akabatanidzwa

Dhizaini itsva yemagineti ine huwandu hwakawanda hwe torque

Mitengo yave ichidzikira gore negore, zvichienda kumashandisirwo ari pakati nepakati

Kuvandudzwa kwetekinoroji yemotokari yeDC:

Mota yeDC isina brushless (BLDC) inopa hupenyu hurefu hwebasa

Mota dzeDC dzakangwara dzine ma encoders akabatanidzwa dziri kutanga kubuda

Kushandiswa kwezvinhu zvitsva kuri kuramba kuchideredza mitengo

VI、 Dhayagiramu yemaitiro ekusarudza anoshanda

Nekutevera nzira inotevera yekuita sarudzo, sarudzo dzinogona kuitwa zvakarongeka:

Mhedziso: Kuwana Kuenzana Pakati Pezvinangwa Zvetekinoroji Nechokwadi Chebhizinesi

Kusarudza pakati pemota ine stepper stepper kana mota yeN20 DC hakusi nyore. Kunoratidza hunyanzvi hwekuenzanisa kushanda kwemainjiniya pamwe nekutonga mitengo yemotokari kuburikidza nekutenga mota.

Nheyo huru dzekuita sarudzo:

Kana kururama uye kuvimbika zviri izvo zvinhu zvikuru zvinofungwa nezvazvo, sarudza mota yestepper

Kana mutengo uye nyore zviri pamusoro, sarudza mota yeDC

Kana uri pakati nepakati, verenga nokungwarira mari yose yesystem uye mari yekuchengetedza kwenguva refu

Munzvimbo yemazuva ano yekuvandudza tekinoroji, mainjiniya akachenjera haabatiriri panzira imwe chete yehunyanzvi, asi vanoita sarudzo dzine musoro zvichibva pazvirambidzo chaizvo uye zvinangwa zvebhizinesi zvepurojekiti. Yeuka, hapana injini "yakanakisisa", mhinduro "yakakodzera" chete.
