Injini ye-Linear stepper, eyaziwa nangokuthiimoto ye-stepper eqondile, iyi-magnetic rotor core ngokusebenzisana nensimu ye-electromagnetic eqhutshwa yi-stator ukukhiqiza ukujikeleza, i-linear stepper motor ngaphakathi kwe-motor ukuguqula ukunyakaza okujikelezayo kube ukunyakaza okuqondile. Ama-linear stepper motor angenza ukunyakaza okuqondile noma ukunyakaza okuqondile okuqondile. Uma i-rotary motor isetshenziswa njengomthombo wamandla ukuguqula ibe ukunyakaza okuqondile, amagiya, izakhiwo ze-cam kanye nezindlela ezifana namabhande noma izintambo kuyadingeka. Ukwethulwa kokuqala kwama-linear stepper motors kwakungo-1968, futhi lesi sibalo esilandelayo sibonisa amanye ama-linear stepper motors ajwayelekile.
Isimiso esiyisisekelo sama-motor aqondile aqhutshwa ngaphandle
I-rotor yemoto ye-stepper eqondile eqhutshwa ngaphandle iyimagnethi ehlala njalo. Lapho ugesi ugeleza ngokugoqa i-stator, ukugoqa i-stator kukhiqiza insimu yamagnetic ye-vector. Le nsimu yamagnetic iqhuba i-rotor ukuthi ijikeleze nge-engeli ethile, ukuze isiqondiso sensimu yamagnetic ye-rotor sihambisane nesiqondiso sensimu yamagnetic ye-stator. Lapho insimu yamagnetic ye-vector ye-stator ijikeleza nge-engeli. I-rotor nayo ijikeleza nge-engeli nale nsimu yamagnetic. Kokufaka ngakunye kwe-pulse kagesi, i-rotor kagesi ijikeleza nge-engeli eyodwa futhi iqhubekele phambili ngesinyathelo esisodwa. Ikhipha ukufuduka kwe-angular okuhambisana nenani lama-pulse okufakwayo kanye nesivinini esihambisana nemvamisa ye-pulse. Ukushintsha i-oda lokunika amandla okugoqa kubuyisela emuva imoto. Ngakho-ke ukuzungeza kwe-stepper motor kungalawulwa ngokulawula inani lama-pulse, imvamisa kanye ne-oda lokunika amandla ama-windings emoto wesigaba ngasinye.
Injini isebenzisa isikulufu njenge-axis ephumayo, futhi inathi yokushayela yangaphandle ixhunywe nesikulufu ngaphandle kwenjini, ithatha indlela ethile yokuvimbela inathi yesikulufu ukuthi ingaphendukeli komunye nomunye, ngaleyo ndlela ifinyelele ukunyakaza okuqondile. Umphumela uwumklamo olula kakhulu ovumela ukusetshenziswa kwama-motor aqondile aqondile ngokuqondile ukunyakaza okuqondile ezicelweni eziningi ngaphandle kokufakwa kokuxhumanisa kwangaphandle kwemishini.
Izinzuzo zama-linear motors aqhutshwa ngaphandle
Ama-motor e-stripper screw aqondile angashintsha amasilinda ku-ezinye izinhlelo zokusebenza, ukufeza izinzuzo ezifana nokubeka kahle, isivinini esilawulekayo, kanye nokunemba okuphezulu. Ama-motor e-linear screw stepper asetshenziswa ezinhlobonhlobo zezicelo kufaka phakathi ukukhiqiza, ukulinganisa ngokunemba, ukulinganisa uketshezi ngokunemba, ukunyakaza kwesikhundla ngokunemba, kanye nezinye izindawo eziningi ezinezidingo zokunemba okuphezulu.
▲Ukunemba okuphezulu, ukunemba kokubeka okuphindaphindwayo kuze kufike ku-± 0.01mm
Injini yokunyathela isikulufu esiqondile inciphisa inkinga yokubambezeleka kokuxhunyaniswa ngenxa yendlela elula yokudlulisa, ukunemba kokubeka, ukuphindaphindeka kanye nokunemba okuphelele. Kulula ukukufeza kune-"rotary motor + screw". Ukunemba kokubeka okuphindaphindiwe kwesikulufu esivamile senjini yokunyathela isikulufu esiqondile kungafinyelela ku-±0.05mm, kanti ukunemba kokubeka okuphindaphindiwe kwesikulufu sebhola kungafinyelela ku-±0.01mm.
▲ Isivinini esiphezulu, kufika ku-300m/min
Ijubane lenjini yokunyathela isikulufu esiqondile lingu-300m/min kanti ukusheshisa kungu-10g, kanti ijubane lenjini yokunyathela isikulufu esiqondile lingu-120m/min kanti ukusheshisa kungu-1.5g. Futhi ijubane lenjini yokunyathela isikulufu esiqondile lizothuthukiswa kakhulu ngemva kokuxazulula inkinga yokushisa ngempumelelo, kuyilapho ijubane "elijikelezayo" lenjini yokunyathela isikulufu esiqondile kanye nebhola lilinganiselwe ngesivinini, kodwa kunzima ukuthuthukisa okwengeziwe.
Impilo ephezulu kanye nokugcinwa okulula
Injini yokunyathela izikulufo eziqondile ifanelekela ukunemba okuphezulu ngoba akukho ukuxhumana phakathi kwezingxenye ezihambayo nezingxenye eziqinile ngenxa yesikhala sokufaka futhi akukho ukuguguleka ngenxa yokunyakaza okubuyela emuva kwesivinini esikhulu kwabathuthi. Isikulufo sebhola asikwazi ukuqinisekisa ukunemba kokunyakaza okubuyela emuva kwesivinini esikhulu, futhi ukungqubuzana kwesivinini esikhulu kuzobangela ukuguguleka kwe-screw nut, okuzothinta ukunemba kokunyakaza futhi akukwazi ukuhlangabezana nesidingo sokunemba okuphezulu.
Ukukhethwa kwemoto eqondile yokushayela yangaphandle
Uma senza imikhiqizo noma izixazululo ezihlobene nokunyakaza okuqondile, siphakamisa ukuthi onjiniyela bagxile kumaphuzu alandelayo.
1. Uyini umthwalo wesistimu?
Umthwalo wesistimu uhlanganisa umthwalo omile kanye nomthwalo oguqukayo, futhi ngokuvamile ubukhulu bomthwalo bunquma usayizi oyisisekelo wemoto.
Umthwalo oqinile: ukusunduza okuphezulu kakhulu okungamelana nesikulufu lapho siphumule.
Umthwalo oguqukayo: ukusunduza okuphezulu kakhulu okungamelana nesikulufu uma sisebenza.
2. Iyini ijubane lokusebenza eliqondile lenjini?
Ijubane lokusebenza kwenjini eqondile lihlobene eduze nomugqa wesikulufu, ukujikeleza okukodwa kwesikulufu kungumugqa owodwa we-nut. Ngejubane eliphansi, kuyalulekwa ukukhetha isikulufu esinomugqa omncane, kanti ngejubane eliphezulu, kuyalulekwa ukukhetha isikulufu esikhulu.
3. Iyini imfuneko yokunemba yesistimu?
Ukunemba kwesikulufu: ukunemba kwesikulufu ngokuvamile kulinganiswa ngokunemba okuqondile, okungukuthi iphutha phakathi kokuhamba kwangempela nokuhamba okungokwemfundiso ngemva kokuba isikulufu sijikeleza ukuze kube yindilinga eyomile ebabayo.
Ukunemba kokubeka okuphindayo: ukunemba kokubeka okuphindayo kuchazwa njengokunemba kohlelo ukuze lukwazi ukufinyelela isikhundla esibekiwe ngokuphindaphindiwe, okuyisibonakaliso esibalulekile sohlelo.
Ukubuyela emuva: ukubuyela emuva kwesikulufu kanye nenathi lapho kuphumule khona lapho inani elihambisanayo elihambisanayo eliyi-axial. Njengoba isikhathi sokusebenza sanda, ukubuyela emuva kuzokwanda ngenxa yokuguga. Isinxephezelo noma ukulungiswa kokubuyela emuva kungatholakala ngenathi yokususa ukubuyela emuva. Uma kudingeka ukubeka izinhlangothi ezimbili, ukubuyela emuva kuyinkinga.
4. Ezinye izinketho
Izinkinga ezilandelayo nazo zidinga ukucatshangelwa enqubweni yokukhetha: Ingabe ukufakwa kwe-linear stepper motor kuyahambisana nomklamo wemishini? Uzoxhuma kanjani into ehambayo ne-nut? Iyini i-stroke ephumelelayo yenduku yesikulufu? Hlobo luni lwe-drive oluzohambisana?
