Ekusebenzeni okuvamile,injini ye-stepperinyakazisa i-engeli yesinyathelo esisodwa, okungukuthi isinyathelo esisodwa phambili, nge-pulse ngayinye yokulawula etholakele. Uma ama-pulse okulawula efakwa njalo, injini ijikeleza njalo ngokufanele. I-motor ephuma esinyathelweni ifaka isinyathelo esilahlekile kanye nesinyathelo esingaphezulu. Uma isinyathelo silahlekile, inani lezinyathelo ezithuthukisiwe yi-rotor lingaphansi kwenani lama-pulse; lapho isinyathelo siwela, inani lezinyathelo ezithuthukisiwe yi-rotor lingaphezu kwenani lama-pulse. Inani lezinyathelo zesinyathelo esisodwa esilahlekile kanye nesinyathelo esingaphezulu lilingana ne-integer multiple yenani lama-beats okugijima. Ukulahlekelwa okukhulu kwesinyathelo kuzokwenza i-rotor ihlale endaweni eyodwa noma idlidlize izungeze indawo eyodwa, futhi i-upload enkulu yesinyathelo izokwenza i-motor idlule.
Ukulahlekelwa yimbangela yesinyathelo kanye nesu
(1) Ukusheshisa kwe-rotor kuhamba kancane kunensimu kazibuthe ejikelezayo ye-injini ye-stepper
Incazelo:
Uma ukusheshisa kwe-rotor kuhamba kancane kunensimu yamagnetic ejikelezayo yemoto ye-stepper, okungukuthi, iphansi kunejubane lokushintsha isigaba, imoto ye-stepper ikhiqiza okungaphandle kwesinyathelo. Lokhu kungenxa yokungena kwamandla okwanele kumoto kanye ne-torque yokuvumelanisa ekhiqizwa kumoto ye-stepper ayivumeli isivinini se-rotor ukuthi silandele ijubane lokujikeleza lensimu yamagnetic ye-stator, ngaleyo ndlela kubangele ukuphuma kwesinyathelo. Njengoba i-torque yokukhipha enamandla yemoto ye-stepper incipha njengoba imvamisa yokusebenza okuqhubekayo ikhuphuka, noma yimuphi imvamisa yokusebenza ephakeme kunalokho izokhiqiza isinyathelo esilahlekile. Lokhu kulahlekelwa kwesinyathelo kubonisa ukuthi imoto ye-stepper ayinayo i-torque eyanele futhi ayinawo amandla okudonsa anele.
Isixazululo:
a. Yenza i-torque kagesi ekhiqizwa yi-stepping motor ngokwayo ikhuphuke. Lokhu kungaba kububanzi bamanje obulinganiselwe ukwandisa ugesi wokushayela; kububanzi be-torque obuphezulu akwanele, ungathuthukisa i-voltage yokushayela yesekethe yokushayela; shintsha ukusebenzisa i-torque enkulu yokugibela i-motor, njll. b, ukuze i-stepping motor idinga ukunqoba i-torque incishiswe. Lokhu kungenziwa ngokunciphisa ngokufanele imvamisa yokusebenza kwe-motor ukuze kwandiswe i-torque yokukhipha ye-motor; ukubeka isikhathi eside sokusheshisa ukuze i-rotor ithole amandla anele.
(2) Isivinini esimaphakathi se-rotor siphakeme kunesivinini esimaphakathi sokujikeleza kwensimu kazibuthe ye-stator
Incazelo:
Ijubane elimaphakathi le-rotor liphakeme kunejubane elimaphakathi lokujikeleza lensimu yamagnetic ye-stator, lapho i-stator inikwa amandla futhi ivuselelwa isikhathi eside kunesikhathi esidingekayo ukuze i-rotor iqhubekele phambili, khona-ke i-rotor ithola amandla amaningi kakhulu ngesikhathi senqubo yokunyathela, okwenza i-torque yokukhipha ekhiqizwa yi-stepping motor ikhuphuke, okwenza imoto idlulele. Uma i-stepping motor isetshenziselwa ukushayela lezo zindlela ezenza umthwalo uhambe phezulu naphansi, kungenzeka kakhulu ukuthi ikhiqize isimo sokudlula, okubangelwa iqiniso lokuthi i-torque edingwa yi-motor iyancipha lapho umthwalo wehla.
Isixazululo:
Nciphisa amandla okushayela enjini yokunyathela ukuze unciphise i-torque yokukhipha yenjini yokunyathela.
(3) Ukungabi namandlainjini yokunyathelakanye nomthwalo eliwuthwalayo
Incazelo:
Ngenxa yokungaqini kwenjini yokunyathela kanye nomthwalo ewuthwalayo, injini ayikwazi ukuqaliswa futhi imiswe ngokushesha ngesikhathi sokusebenza, kodwa isinyathelo esilahlekile siyenzeka ngesikhathi sokuqala kanye nesinyathelo esingaphezu kwesinyathelo ngesikhathi sokuma.
Isixazululo:
Ngokusebenzisa inqubo yokusheshisa nokwehlisa ijubane, okungukuthi ukuqala ngesivinini esiphansi, bese usheshisa kancane kancane uye ekusebenzeni kwesivinini esithile, bese wehlisa ijubane kancane kancane kuze kube yilapho ume. Ukusheshisa okunengqondo nokubushelelezi nokulawula ukunciphisa ijubane kuyisihluthulelo sokuqinisekisa ukusebenza okuthembekile, okusebenzayo nokunembile kohlelo lwe-stepper drive.
(4) Ukuqina kwenjini yokunyathela
Incazelo:
Ukuzwakala kwezwi nakho kuyimbangela yokungahambi kahle. Uma imoto ye-stepper isebenza ngokuqhubekayo, uma imvamisa ye-control pulse ilingana nemvamisa yangaphakathi yemoto ye-stepper, kuzovela i-resonance. Phakathi nesikhathi esisodwa se-control pulse, ukudlidliza akuncishisiwe ngokwanele, bese i-pulse elandelayo ifika, ngakho-ke iphutha eliguqukayo eduze kwemvamisa ye-resonance likhulu kunawo wonke futhi lizobangela ukuthi imoto ye-stepper ilahlekelwe yisinyathelo.
Isixazululo:
Nciphisa ngokufanele ugesi we-stepper motor; sebenzisa indlela yokuhlukanisa i-division drive; sebenzisa izindlela zokunciphisa umswakama, okuhlanganisa nendlela yokunciphisa umswakama ngomshini. Zonke izindlela ezingenhla zingaqeda ngempumelelo ukushukuma kwe-motor futhi zigweme isimo sokungalandeli isinyathelo.
(5) Ukulahlekelwa ukushaya kwenhliziyo lapho kushintsha indlela
Incazelo:
Kuboniswa ukuthi inembile kunoma iyiphi indlela, kodwa iqoqa ukuphambuka ngokushesha nje lapho indlela ishintsha, futhi lapho ishintsha kaningi, kulapho iphambuka khona kakhulu.
Isixazululo:
I-general stepper drive esiqondisweni kanye nezimpawu ze-pulse zinezidingo ezithile, njengokuthi: isiqondiso sesignali ku-pulse yokuqala eceleni komphetho okhuphukayo noma umphetho owela phansi (izidingo ezahlukene ze-drive azifani) ngaphambi kokufika kwama-microsecond ambalwa okuzonqunywa, ngaphandle kwalokho kuzoba ne-pulse ye-engeli yokusebenza kanye nesidingo sangempela sokuphendukela kolunye uhlangothi, futhi ekugcineni isenzakalo sokuhluleka sibonakala lapho uhamba uthambekele kakhulu, lapho ukuwohloka kuncane kakhulu, ikhambi lisetshenziswa kakhulu kusofthiwe ukushintsha i-logic yokuthumela i-pulse Isixazululo ikakhulukazi ukusebenzisa isofthiwe ukushintsha i-logic yokuthumela ama-pulse noma ukwengeza ukubambezeleka.
(6) Amaphutha esofthiwe
Incazelo:
Izinqubo zokulawula eziholela esinyathelweni esilahlekile azivamile, isidingo sokuhlola uhlelo lokulawula akuyona inkinga.
Isixazululo:
Angikwazi ukuthola imbangela yenkinga isikhathi esithile, kukhona nonjiniyela abazovumela imoto ye-stepper ukuthi isebenze isikhathi esithile ukuze bathole kabusha imvelaphi yayo.
