Ngokuthuthuka kwe-microelectronics kanye nobuchwepheshe bokukhiqiza ngokunemba, isidingo sama-stepper motors siyakhula usuku nosuku, futhi ama-stepper motors kanye nendlela yokudlulisa amagiya kuhlanganiswe ebhokisini lamagiya okunciphisa, kodwa futhi nasezimweni eziningi zokusetshenziswa ukubona, namuhla kuncane futhi wonke umuntu ndawonye ukuqonda lolu hlobo lwendlela yokudlulisa amagiya okunciphisa.

 

Ama-stepper motors ancipha kanjani?

Imoto ye-Stepper njengemoto yokushayela esetshenziswa kakhulu, evame ukusetshenziswa nemishini yokwehlisa ijubane ukuze kufezwe umphumela omuhle wokudlulisa; kanti imoto ye-stepper ivame ukusetshenziswa imishini yokwehlisa ijubane nezindlela, njengebhokisi lamagiya okunciphisa, i-encoder, isilawuli, isignali ye-pulse, njll.

 

Ukwehla kwesignali ye-pulse:Isivinini sokuzungeza imoto ye-stepper, sisekelwe ekushintsheni kwesignali ye-pulse yokufaka ukuze ishintshe. Ngokombono, nikeza umshayeli i-pulse, imoto ye-stepper izungeza i-angle yesinyathelo (ukuhlukaniswa kwe-angle yesinyathelo sokuhlukanisa). Empeleni, uma isignali ye-pulse ishintsha ngokushesha kakhulu, imoto ye-stepper ngenxa yomphumela wangaphakathi wokudambisa we-reverse electric potential, impendulo yamagnetic phakathi kwe-rotor ne-stator ngeke ilandele ushintsho kusignali kagesi, izoholela ekuvinjweni nasekulahlekeni kwezinyathelo.

 

Ukunciphisa ijubane lebhokisi lokunciphisa:I-stepper motor ifakwe i-reduce gearbox esetshenziswa ndawonye, ​​i-stepper motor output high speed, i-torque speed ephansi, exhunywe ku-reduce gearbox, i-gear gear yangaphakathi yokunciphisa isethi yokudlulisa i-meshing eyenziwe yi-reduce ratio, i-stepper motor output high speed izoncishiswa, futhi ithuthukise i-transmission torque ukuze kufezwe umphumela wokudlulisa ofanele; umphumela wokunciphisa uncike ku-reduce ratio ye-gearbox, lapho isilinganiso sokunciphisa sikhulu, isivinini sokukhipha sincane, futhi ngokuphambene nalokho. Futhi ngokuphambene nalokho.

 

Isivinini sokulawula i-Curve exponential:Ijika le-exponential, ohlelweni lwesofthiwe, ama-constants esikhathi abalwa kuqala agcinwe kwimemori yekhompyutha, akhomba ekukhetheni lapho kusebenza. Ngokuvamile, ukuqedwa kokusheshisa kwe-stepper motor kanye nesikhathi sokunciphisa ijubane sama-300ms noma ngaphezulu. Uma usebenzisa isikhathi esifushane kakhulu sokusheshisa kanye nokunciphisa ijubane, iningi lama-stepper motors, kuzoba nzima ukufeza ukujikeleza kwesivinini esikhulu kwama-stepper motors.

 

Ukunciphisa ijubane lokulawula i-encoder:Ukulawulwa kwe-PID njengendlela yokulawula elula nesebenzayo, ku-stepper motor drive kuthole ukusetshenziswa okubanzi. Kusekelwe enanini elinikeziwe r (t) kanye nenani langempela lokukhipha c (t) ukwakha ukuphambuka kokulawula e (t), ukuphambuka kokulingana, okuhlanganisiwe kanye nokwehluka ngokusebenzisa inhlanganisela eqondile yenani lokulawula, ukulawula into yokulawula. Iphepha lisebenzisa inzwa yesikhundla ehlanganisiwe ku-motor ye-stepper enezigaba ezimbili futhi liklama isilawuli sejubane le-PI esilungisekayo ngokuzenzakalelayo ngokusekelwe ku-detector yesikhundla kanye nokulawula kwe-vector, enikeza izici zesikhashana ezanelisayo ngaphansi kwezimo zokusebenza eziguquguqukayo. Ngokusekelwe kumodeli yezibalo ye-stepper motor, uhlelo lokulawula lwe-PID lwe-stepper motor luklanywe futhi i-algorithm yokulawula ye-PID isetshenziselwa ukuthola inani lokulawula ukulawula ukunyakaza kwe-motor endaweni ecacisiwe. Okokugcina, kuqinisekiswa ngokulingisa ukuthi ukulawula kunezici ezinhle zokuphendula eziguquguqukayo. Isilawuli se-PID sinezinzuzo zesakhiwo esilula, ukuqina okuphezulu kanye nokuthembeka okuphezulu, kodwa asikwazi ukubhekana ngempumelelo nolwazi olungaqinisekile ohlelweni.

 

Injini ye-Stepper ingalinganiswa neyiphi i-reducer? Ku-stepper motor kanye ne-gearbox package yokukhetha udinga ukunaka lezo zici, futhi hlobo luni lwe-gearbox olungakhethwa ukuze lusetshenziswe ndawonye?

 

1. Isizathu semoto ye-stepper ene-reducer

 

I-Stepper motor ishintsha imvamisa yamanje wesigaba se-stator, njengokushintsha i-input pulse yesekethe ye-stepper motor drive, ukuze ibe ukunyakaza kwesivinini esiphansi. I-stepper motor yesivinini esiphansi ilinde umyalo wesinyathelo, i-rotor imile, ekunyathelweni kwesivinini esiphansi, ukuguquguquka kwesivinini kuzoba kukhulu kakhulu, ngalesi sikhathi, njengokushintsha ekusebenzeni kwesivinini esiphezulu, ingaxazulula inkinga yokuguquguquka kwesivinini, kodwa i-torque ngeke yanele. Okusho ukuthi, ukuguquguquka kwe-torque yesivinini esiphansi, futhi isivinini esikhulu ngeke sanele i-torque, isidingo sokusebenzisa i-reducer.

 

2. Injini ye-Stepper ivame ukuba ne-reducer

 

I-Reducer uhlobo lwe-gear drive, i-worm drive, i-gear - worm drive, evalelwe ekhasethini eliqinile, ivame ukusetshenziswa njenge-reducer phakathi kwe-prime mover nomshini wokusebenza, phakathi kwe-prime mover nomshini wokusebenza noma i-actuator ukuze ifane nesivinini kanye nokudluliselwa kwe-torque; i-reducer inobubanzi obubanzi, ngohlobo lokudluliselwa ingahlukaniswa ibe yi-gear reducer, i-worm gear reducer kanye ne-planetary gear reducer. Ngokwenani lezigaba zokudlulisela zingahlukaniswa zibe yi-single-stage kanye ne-multi-stage reducer; ngokwesimo se-gear ingahlukaniswa ibe yi-cylindrical gear reducer, i-bevel gear reducer kanye ne-bevel-cylindrical gear reducer; ngokwesimo se-transmission form ingahlukaniswa ibe yi-unfolded reducer, i-shunt reducer kanye ne-coaxial reducer. I-Stepper motor assembly reducers yi-planetary reducer, i-worm gear reducer, i-parallel gear reducer, i-filament gear reducer.

 

 

Kuthiwani ngokunemba kwe-stepper motor planetary reducer?

 

 

Ukunemba kwe-reducer kubizwa nangokuthi i-return clearance. Uma ukuphela kokukhipha kulungisiwe futhi ukuphela kokufaka kujikeleziswa ngokwewashi nangokuphambene newashi ukuze kukhiqizwe i-torque elinganisiwe +-2% torque ekugcineni kokukhipha, kuba nokufuduka okuncane kwe-angular ekugcineni kokufaka kwe-reducer, futhi lokhu kufuduka kwe-angular kuyi-return clearance. Iyunithi "imizuzu ye-arc", okungukuthi ingxenye eyodwa kwezingamashumi ayisithupha yedigri. Amanani ajwayelekile okubuyiselwa kwe-return clearance abhekisela ohlangothini lokukhipha lwebhokisi legiya. I-Stepper motor planetary reducer inokuqina okuphezulu, ukunemba okuphezulu (isigaba esisodwa singafinyelelwa ngaphakathi komzuzu owodwa), ukusebenza kahle kokudlulisa okuphezulu (isigaba esisodwa ku-97%-98%), isilinganiso se-torque/volume esiphezulu, akukho ukunakekelwa, njll.

 

Ukunemba kokudluliselwa kwe-Stepper motor akulungiseki, i-engeli yokugijima kwe-stepper motor inqunywa ngokuphelele ubude besinyathelo kanye nenani lama-pulse, futhi inani lama-pulse lingaba inani eliphelele, inani ledijithali aliyona umqondo wokunemba, isinyathelo esisodwa yisinyathelo esisodwa, izinyathelo ezimbili yizinyathelo ezimbili. Ukunemba kwamanje okungalungiswa ukunemba kokubuyiselwa kwegiya kwebhokisi legiya leplanethi.

 

1. Indlela yokulungisa ukunemba kwe-Spindle:ukulungiswa kokunemba kokujikeleza kwe-spindle ye-planetary gearbox, uma iphutha lomshini we-spindle ngokwalo lihlangabezana nezidingo, khona-ke ukunemba kokujikeleza kwe-spindle ye-reducer ngokuvamile kunqunywa yi-bearing. Isihluthulelo sokulungisa ukunemba kokujikeleza kwe-spindle ukulungisa i-bearing clearance. Ukugcina i-bearing clearance efanele kubalulekile ekusebenzeni kwezingxenye ze-spindle kanye nokuphila kwe-bearing. Ku-bearing rolling, lapho kune-clearance enkulu, ngeke nje kwenze umthwalo ugxile emzimbeni ogoqayo ohlangothini lwamandla, kodwa futhi kuzokhiqiza isenzakalo esibucayi sokugxilisa ingqondo ekuxhumaneni kwe-bearing yangaphakathi neyangaphandle ye-bearing, kufinyeze impilo ye-bearing, futhi kwenze i-spindle centerline drift, kube lula ukubangela ukudlidliza kwezingxenye ze-spindle. Ngakho-ke, ukulungiswa kwe-bearing rolling kumele kulayishwe kusengaphambili, Ukuze kukhiqizwe inani elithile lokuphazamiseka ngaphakathi kwe-bearing, ukuze kukhiqizwe ukuguqulwa okuthile kwe-elastic ekuxhumaneni phakathi komzimba ogoqayo kanye ne-internal ne-outer ring raceway, ngaleyo ndlela kuthuthukiswe ukuqina kwe-bearing.

2. Indlela yokulungisa igebe:Ibhokisi lamagiya eplanethi enkambisweni yokunyakaza lizokhiqiza ukungqubuzana, okubangela ushintsho ngobukhulu, ukuma kanye nekhwalithi yobuso phakathi kwezingxenye, kanye nokuguguleka, ukuze igebe phakathi kwezingxenye likhuphuke, sidinga ukwenza uhla olufanele lokulungisa ukuqinisekisa ukunemba kokunyakaza okuhlobene phakathi kwezingxenye.

 

3. Indlela yokubuyisela amaphutha:izingxenye ngokwazo ziyaphambuka ngokusebenzisa inhlangano efanele, ukuze isimo sokushintshana phakathi kwesikhathi sokuphumula, ukuqinisekisa ukunemba kwendlela yokunyakaza kwemishini.

 

1. Indlela ephelele yesinxephezelo:Ithuluzi elifakwe ne-reducer uqobo ukuze lenze ukucubungula lidluliselwe ngokulungiswa okufanele kwetafula lomsebenzi ukuze kususwe imiphumela ehlanganisiwe yokunemba kwamaphutha.
