Ekusebenzeni okujwayelekile, ii-stepper motorinyakazisa i-engeli yesinyathelo esisodwa, okungukuthi isinyathelo esisodwa phambili, ku-pulse ngayinye yokulawula etholiwe. Uma ama-control pulses efakwa ngokuqhubekayo, injini ijikeleza ngokuqhubekayo ngokufanele. Ukukhipha i-motor esinyathelweni kufaka phakathi isinyathelo esilahlekile kanye ne-overstep. Uma isinyathelo silahlekile, inani lezinyathelo ezithuthukisiwe yi-rotor lingaphansi kwenani lama-pulses; lapho isinyathelo siwela, inani lezinyathelo ezithuthukisiwe yi-rotor lingaphezu kwenani lama-pulses. Inombolo yezinyathelo zesinyathelo esisodwa esilahlekile kanye nesitebhisi silingana nenombolo ephelele yokuphindaphinda yenani lamabhithi agijimayo. Ukulahlekelwa kwesinyathelo esingathi sína kuzobangela i-rotor ukuthi ihlale endaweni eyodwa noma idlidlize izungeze indawo eyodwa, futhi ukweqa okubucayi kuzobangela ukuthi injini idubule kakhulu.
Ukulahlekelwa yisinyathelo kanye namasu
(1) Ukusheshisa kwe-rotor kuhamba kancane kunenkundla yamagnetic ejikelezayoi-stepper motor
Incazelo:
Lapho ukusheshisa kwe-rotor kuhamba kancane kunenkundla yamagnetic ejikelezayo ye-stepper motor, okungukuthi, ephansi kunejubane lokushintsha kwesigaba, i-stepper motor ikhiqiza ngaphandle kwesinyathelo. Lokhu kubangelwa ukufakwa kwamandla okunganele ku-motor kanye ne-torque yokuvumelanisa eyenziwe ku-stepper motor ayivumeli isivinini se-rotor ukulandela isivinini sokujikeleza kwe-stator magnetic field, ngaleyo ndlela kubangele ukuphuma kwesinyathelo. Njengoba i-torque eguquguqukayo yokuphuma kwe-stepper motor iyancipha njengoba imvamisa yokusebenza okuqhubekayo ikhuphuka, noma iyiphi imvamisa yokusebenza ephakeme kunaleyo izoveza isinyathelo esilahlekile. Lokhu kulahlekelwa kwesinyathelo kubonisa ukuthi i-stepper motor ayinayo i-torque eyanele futhi ayinawo amandla okwanele okudonsa.
Isixazululo:
a. Yenza i-torque ye-electromagnetic ekhiqizwe yi-steping motor ngokwayo ikhule. Lokhu kungaba sebangeni lamanje elilinganiselwe ukuze kwandiswe amandla okushayela; ebangeni le-torque ephezulu akwanele, ungathuthukisa i-voltage yokushayela yesekethe yokushayela; shintsha ukusebenzisa i-torque stepping motor enkulu, njll. b, ukuze injini yokunyathela idinga ukunqoba i-torque iyancipha. Lokhu kungenziwa ngokunciphisa ngokufanelekile imvamisa yokusebenza kwemoto ukuze kwandiswe i-torque ephumayo yenjini; ukubeka isikhathi eside sokusheshisa ukuze i-rotor ithole amandla anele.
(2) Isivinini esimaphakathi se-rotor siphezulu kunesilinganiso sokujikeleza kwesivinini se-stator magnetic field
Incazelo:
Isivinini esimaphakathi se-rotor siphezulu kunesilinganiso sokujikeleza kwe-stator magnetic field, lapho i-stator inikwe amandla futhi ijabule isikhathi eside kunesikhathi esidingekayo ukuze i-rotor iqhubekele phambili, khona-ke i-rotor ithola amandla amaningi kakhulu ngesikhathi senqubo yokunyathela, okwenza i-torque ephumayo ikhiqizwe ukunyuka kwemoto, ngaleyo ndlela ibangele ukuthi injini idlule. Uma isitebhisi semoto sisetshenziswa ukushayela lezo zindlela ezenza umthwalo wehle uye phezulu, maningi amathuba okuthi ukhiqize ukwenzeka kokudlula ngokweqile, okubangelwa ukuthi i-torque edingwa yinjini iyehla lapho umthwalo wehla.
Isixazululo:
Yehlisa idrayivu yamanje ye-steping motor ukuze wehlise i-torque ephumayo ye-steping motor.
(3) Inertia yeukunyathela motornomthwalo ewuthwalayo
Incazelo:
Ngenxa ye-inertia ye-steping motor ngokwayo kanye nomthwalo owuthwalayo, i-motor ayikwazi ukuqaliswa futhi imiswe ngokushesha ngesikhathi sokusebenza, kodwa isinyathelo esilahlekile senzeka ngesikhathi sokuqala futhi kwenzeka ukweqa ngesikhathi sokuma.
Isixazululo:
Ngenqubo yokusheshisa neyokwehlisa ijubane, okungukuthi, ukuqala ngesivinini esiphansi, bese kancane kancane kusheshise ukusebenza kwejubane elithile, bese kwehla kancane kancane kuze kumiswe. Ukusheshisa okunengqondo nokushelelayo nokulawulwa kokunciphisa kuyisihluthulelo sokuqinisekisa ukusebenza okuthembekile, okuphumelelayo nokunembile kwesistimu ye-stepper drive.
(4) Ukuzwakala kwenjini yokunyathela
Incazelo:
I-resonance nayo iyimbangela yokuphuma kwesinyathelo. Lapho i-stepper motor isebenza ngokuqhubekayo, uma imvamisa ye-pulse yokulawula ilingana nemvamisa yangaphakathi ye-stepper motor, i-resonance izokwenzeka. Ngaphakathi kwesikhathi esisodwa sokulawula ishayela, ukudlidliza akunciphisiwe ngokwanele, futhi ishayela elilandelayo liyafika, ngaleyo ndlela iphutha eliguquguqukayo eliseduze nefrikhwensi ye-resonance likhulu kakhulu futhi lizobangela ukuthi i-stepper motor ilahlekelwe isinyathelo.
Isixazululo:
Yehlisa ngokufanele idrayivu yamanje ye-stepper motor; sebenzisa indlela yokuhlukanisa iziqephu; sebenzisa izindlela zokumanzisa, okuhlanganisa indlela yokudambisa ngomshini. Zonke lezi zindlela ezingenhla zingaqeda ngempumelelo i-motor oscillation futhi zigweme ukwenzeka kokuphuma kwesinyathelo.
(5) Ukulahlekelwa ukushaya kwenhliziyo lapho ushintsha indlela
Incazelo:
Kuboniswa ukuthi inembile kunoma iyiphi indlela, kodwa iqongelela ukuchezuka ngokushesha nje lapho isiqondiso sishintshwa, futhi lapho sishintshwa izikhathi eziningi, sichezuka nakakhulu.
Isixazululo:
I-General stepper drive esiqondisweni kanye namasignali we-pulse anezidingo ezithile, njengokuthi: isiqondiso sesignali ku-pulse yokuqala eduze konqenqema olukhuphuka noma onqenqemeni oluwayo (izidingo ezihlukene zokushayela azifani) ngaphambi kokufika kwama-microseconds ambalwa azonqunywa, ngaphandle kwalokho kuzoba ne-pulse ye-angle yokusebenza kanye nesidingo sangempela sokuphendukela kolunye uhlangothi, futhi ekugcineni ukwehluleka kuyabonakala kakhulu ukuwohloka kugqame kakhulu, ikhambi lisetshenziswa ikakhulukazi kusoftware ukuze kuguqulwe i-logic yokuthumela i-pulse Isixazululo ngokuyinhloko ukusebenzisa isofthiwe ukushintsha i-logic yokuthumela ama-pulses noma ukwengeza ukubambezeleka.
(6) Ukonakala kwesoftware
Incazelo:
Izinqubo zokulawula ziholela esinyathelweni esilahlekile akuvamile, isidingo sokuhlola uhlelo lokulawula akuyona inkinga.
Isixazululo:
Awukwazi ukuthola imbangela yenkinga okwesikhashana, kukhona futhi onjiniyela abazovumela i-stepper motor ukuthi isebenze isikhathi esithile ukuze iphinde ithole umsuka we-homing.
