I-Linear stepper motor, eyaziwa nangokuthii-linear stepper motor, iwumgogodla we-rotor kazibuthe ngokuxhumana nensimu ye-electromagnetic pulsed ekhiqizwe i-stator ukukhiqiza ukuzungezisa, i-linear stepper motor ngaphakathi kwenjini ukuguqula ukunyakaza okujikelezayo kube ukunyakaza okuqondile. Ama-Linear stepper motors angenza ukunyakaza komugqa noma ukunyakaza okuphindaphindayo okuqondile ngokuqondile. Uma i-rotary motor isetshenziswa njengomthombo wamandla ukuze iguqulele ukunyakaza okulandelanayo, amagiya, izakhiwo zekhamera nezindlela ezifana namabhande noma izintambo kuyadingeka. Ukwethulwa kokuqala kwamamotho ahamba ngomugqa kwakungo-1968, futhi lesi sibalo esilandelayo sibonisa amanye amamotho ajwayelekile alandelanayo.
Isimiso esiyisisekelo samamotho alayini ashayelwa ngaphandle
I-rotor ye-linear stepper motor eqhutshwa ngaphandle inguzibuthe unomphela. Uma i-current igeleza kumajika e-stator, i-stator winding ikhiqiza inkambu kazibuthe ye-vector. Le nkundla kazibuthe ishayela i-rotor ukuthi ijikeleze nge-engeli ethile, ukuze isiqondiso se-rotor yamandla kazibuthe ahambisane nesiqondiso se-stator's magnetic field. Lapho ivekhtha ye-stator inkambu kazibuthe izungeza nge-engeli. I-rotor iphinde ijikeleze nge-engeli nale nkundla kazibuthe. Okokufaka kwe-pulse kagesi ngakunye, i-rotor kagesi izungeza nge-engeli eyodwa bese ihambisa isinyathelo esisodwa phambili. Ikhipha i-angular displacement ngokulingana nenani lokufakwayo kwe-pulses kanye nesivinini esilinganayo nemvamisa yokushaya kwenhliziyo. Ukushintsha ukuhleleka kwamandla okujikajika kubuyisela emuva injini. Ngakho-ke ukujikeleza kwe-stepper motor kungalawulwa ngokulawula inani lama-pulses, imvamisa kanye nokuhleleka kokunika amandla ama-motor windings wesigaba ngasinye.
Injini isebenzisa isikulufu njenge-eksisi ephumayo, kanye nenathi lokushayela langaphandle libambene nesikulufu ngaphandle kwenjini, lithatha indlela ethile yokuvimbela inathi eliyisikulufu ukuthi lingajikijeli lihlobene nelinye, ngaleyo ndlela kuzuzwe ukunyakaza komugqa. Umphumela uba idizayini eyenziwe lula kakhulu evumela ukusetshenziswa kwamamotho we-stepper aqondile ngokuqondile ukunyakaza okuqondile ezinhlelweni eziningi ngaphandle kokufakwa kokuxhunywa komshini kwangaphandle.
Izinzuzo zamamotho alayini ashayelwa ngaphandle
Amamotho we-screw stepper aqondile angangena esikhundleni samasilindaezinye izinhlelo zokusebenza, ukuzuza izinzuzo ezifana nokuma okunembile, isivinini esilawulekayo, nokunemba okuphezulu. Ama-Linear screw stepper motors asetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezihlanganisa ukukhiqiza, ukulinganisa ukunemba, ukukalwa koketshezi okunembayo, ukunyakaza okuqondile kwendawo, nezinye izindawo eziningi ezinezidingo ezinembayo eziphezulu.
▲Ukunemba okuphezulu, ukunemba kokuma okuphindaphindekayo kufika ku-±0.01mm
I-Linear screw stepping motor inciphisa inkinga ye-interpolation lag ngenxa yendlela elula yokudlulisa, ukunemba kwendawo, ukuphindaphinda kanye nokunemba okuphelele.Kulula ukuyithola kune-"rotary motor + screw". Ukunemba okuphindayo kokuma kwesikulufu esijwayelekile sesikulufu somugqa somugqa singafinyelela ku-±0.05mm, futhi ukunemba okuphindayo kokuma kwesikulufu sebhola kungafinyelela ku-±0.01mm.
▲ Isivinini esikhulu, esingafika ku-300m/min
Ijubane le-linear screw stepping motor ngu-300m/min futhi ukusheshisa ngu-10g, kuyilapho isivinini sesikulufu sebhola singu-120m/min futhi ukusheshisa ngu-1.5g. Futhi ijubane le-linear screw stepping motor lizothuthukiswa nakakhulu ngemva kokuxazulula ngempumelelo inkinga yokushisa, kuyilapho "i-rotary Isivinini se-"servo motor & ball screw" silinganiselwe ngesivinini, kodwa kunzima ukuthuthukisa okwengeziwe.
Impilo ephezulu kanye nokugcinwa kalula
I-linear screw stepping motor ifaneleka ukunemba okuphezulu ngoba akukho ukuthintana phakathi kwezingxenye ezihambayo nezingxenye ezingaguquki ngenxa yegebe elikhuphukayo futhi akukho ukuguga ngenxa yokunyakaza okuphindaphindayo kwesivinini esikhulu sabanyakazi. Isikulufu sebhola asikwazi ukuqinisekisa ukunemba kokunyakaza okuphindaphindayo kwesivinini esikhulu, futhi ukungqubuzana kwesivinini esikhulu kuzobangela ukuguga kwentongomane yesikulufu, okuzothinta ukunemba kokunyakaza futhi akukwazi ukuhlangabezana nesidingo sokunemba okuphezulu.
Ukukhethwa kwenjini yangaphandle yomugqa wedrayivu
Uma senza imikhiqizo ehlobene nokunyakaza okuqondile noma izixazululo, siphakamisa ukuthi onjiniyela bagxile kulawa maphuzu alandelayo.
1. Uyini umthwalo wesistimu?
Umthwalo wesistimu uhlanganisa umthwalo omile nomthwalo oguquguqukayo, futhi ngokuvamile ubukhulu bomthwalo bunquma usayizi oyisisekelo wemoto.
Umthwalo omile: umfutho omkhulu isikulufu esingamelana nawo lapho siphumule.
Umthwalo onamandla: ukuphokophela okuphezulu isikulufu esingamelana naso lapho sinyakaza.
2. Siyini isivinini sokugijima esilandelanayo senjini?
Ijubane lokugijima lenjini yomugqa lihlobene eduze nomthofu wesikulufu, ukuzungeza okukodwa kwesikulufu kuwukuhola okukodwa kwentongomane. Ngejubane eliphansi, kuhle ukukhetha isikulufu esinomthofu omncane, futhi ngesivinini esikhulu, kunconywa ukukhetha isikulufu esikhulu.
3. Iyini imfuneko yokunemba kwesistimu?
Ukunemba kwesikulufu: ukunemba kwesikulufu ngokuvamile kukalwa ngokunemba komugqa, okungukuthi iphutha phakathi kohambo lwangempela kanye nohambo lwethiyori ngemva kokuba isikulufu sizungezisa indilinga eyomile ebabayo.
Phinda ukunemba kokuma: ukunemba kokubeka okuphindayo kuchazwa njengokunemba kwesistimu ukuze ikwazi ukufinyelela endaweni eshiwo ngokuphindaphindiwe, okuyinkomba ebalulekile yohlelo.
Ukuhlehla: ukuhlehla kwesikulufu namantongomane ekuphumuleni lapho inani elinyakazayo le-axial elihlobene. Njengoba isikhathi sokusebenza sikhula, i-backlash nayo izokhula ngenxa yokugqoka. Isinxephezelo noma ukulungiswa kwe-backlash kungafinyelelwa nge-nut yokususa i-backlash. Lapho kudingeka ukuma kwe-bi-directional, ukuhlehla kuyakhathaza.
4. Okunye ukukhetha
Lezi zindaba ezilandelayo nazo zidinga ukucatshangelwa enqubweni yokukhetha: Ingabe ukukhwezwa kwe-linear stepper motor ngokuhambisana nomklamo womshini? Uzoyixhuma kanjani into ehambayo enatini? Iyini i-stroke esebenzayo ye-screw rod? Iluphi uhlobo lokushayela oluzofaniswa?
