Kwintsebenzo eqhelekileyo, ii-motor ye-stepperihambisa i-engile yenyathelo elinye, okt inyathelo elinye ukuya phambili, kwi-pulse yolawulo nganye efunyenweyo. Ukuba ii-pulses zokulawula zifakwe ngokuqhubekayo, i-motor ijikeleza ngokuqhubekayo ngokufanelekileyo. Ukukhupha i-motor ngaphandle kwenyathelo kubandakanya inyathelo elilahlekileyo kunye ne-overstep. Xa inyathelo lilahlekile, inani lamanyathelo aqhutywe yi-rotor lingaphantsi kwenani le-pulses; xa inyathelo liwela, inani lamanyathelo aqhutywe yi-rotor lingaphezulu kwenani lee-pulses. Inani lamanyathelo kwinyathelo elinye elilahlekileyo kunye nokugqitha lilingana nenani elipheleleyo lenani leebhithi ezibalekayo. Ukulahleka kwenyathelo elibi kuya kubangela ukuba i-rotor ihlale kwindawo enye okanye ingcangcazele ijikeleze indawo enye, kwaye inyathelo elibi elingaphaya liya kubangela ukuba imoto idubule.
Ukulahlekelwa ngunobangela wenyathelo kunye neqhinga
(1) Ukukhawuleza kwe-rotor kuyacotha kunomhlaba ojikelezayo wemagnethii-motor ye-stepper
Ingcaciso:
Xa ukukhawuleza kwe-rotor kuhamba kancinci kunommandla ojikelezayo wamagnetic we-motor stepper, oko kukuthi, ngaphantsi kwesantya sokutshintsha kwesigaba, i-motor stepper yenza ngaphandle kwesinyathelo. Oku kubangelwa igalelo lamandla anganeleyo kwi-motor kunye ne-torque yokuvumelanisa eyenziwe kwi-motor stepper ayivumeli isantya se-rotor ukuba silandele isantya sokujikeleza kwe-stator magnetic field, ngaloo ndlela ibangela ukuphuma-kwenyathelo. Kuba i-torque eguquguqukayo yemveliso ye-stepper motor iyancipha njengoko isantya sokusebenza ngokuqhubekayo sinyuka, nayiphi na i-frequency yokusebenza ephezulu kunoko iya kuvelisa inyathelo elilahlekileyo. Le lahleko yenyathelo ibonisa ukuba i-stepper motor ayinayo i-torque eyaneleyo kwaye ayinayo umthamo owaneleyo wokutsala.
Isisombululo:
a. Yenza i-torque ye-electromagnetic eveliswe yimoto yokunyathela ngokwayo yonyuke. Oku kunokuba kuluhlu lwangoku olulinganisiweyo ukunyusa umbane wokuqhuba; kwi-high-frequency range of torque akwanele, unokuphucula i-voltage yokuqhuba isiphaluka sokuqhuba; utshintsho ukusebenzisa torque ukunyathela motor enkulu, njl b, ukuze ukunyathela motor kufuneka ukoyisa torque kuncitshiswe. Oku kunokwenziwa ngokunciphisa ngokufanelekileyo i-frequency ye-motor yokusebenza ukwenzela ukwandisa i-torque ye-motor; ukubeka ixesha elide lokukhawuleza ukwenzela ukuba i-rotor ifumane amandla aneleyo.
(2) Isantya somndilili we-rotor siphezulu kunesantya somndilili wokujikeleza we-stator magnetic field
Ingcaciso:
Isantya esiphakathi se-rotor siphezulu kunesantya esijikelezayo se-stator magnetic field, xa i-stator inikwe amandla kwaye ivuya ixesha elide kunexesha elifunekayo ukuze i-rotor iqhube phambili, emva koko i-rotor ifumana amandla amaninzi ngexesha lenkqubo yokunyathela, eyenza i-torque ephumayo iveliswe kukunyuka kwemoto, ngaloo ndlela ibangela ukuba i-motor igqithe. Xa i-motor yokunyathela isetyenziselwa ukuqhuba ezo ndlela zenza umthwalo unyuke kwaye uhle, kunokwenzeka ukuba uvelise isenzeko sokugqithisa, okubangelwa kukuba i-torque efunwa yi-motor iyancipha xa umthwalo uhla.
Isisombululo:
Ukunciphisa i-drive yangoku ye-motor yokunyathela ukuze unciphise i-torque ye-motor yokunyathela.
(3) Inertia yeukunyathela injininomthwalo owuthweleyo
Ingcaciso:
Ngenxa ye-inertia yemoto yokunyathela ngokwayo kunye nomthwalo owuthweleyo, i-motor ayikwazi ukuqaliswa kwaye imiswe ngokukhawuleza ngexesha lokusebenza, kodwa inyathelo elilahlekileyo lenzeka ngexesha lokuqala kwaye ukugqithisa kwenzeka ngexesha lokumisa.
Isisombululo:
Ngokusebenzisa inkqubo yokunyusa isantya kunye nokwehlisa isantya, oko kukuthi, ukuqala ngesantya esisezantsi, emva koko unyuke ngokuthe chu ukuya kwisantya esithile sokusebenza, emva koko wehlise ngokuthe ngcembe de ume. Ukukhawulezisa okunengqiqo kunye nokugudileyo kunye nolawulo lokunciphisa isitshixo sokuqinisekisa ukusebenza okuthembekileyo, okusebenzayo kunye nokuchanekileyo kwenkqubo ye-stepper drive.
(4) Ukuvakala kwenjini yokunyathela
Ingcaciso:
I-resonance ikwangunobangela wokuphuma kwinqanaba. Xa i-motor stepper isebenza ngokuqhubekayo, ukuba i-frequency ye-pulse yokulawula ilingana ne-intrinsic frequency ye-motor stepper, i-resonance iya kwenzeka. Ngaphakathi kwexesha elinye lokulawula i-pulse, ukungcangcazela akuthintelwanga ngokwaneleyo, kwaye i-pulse elandelayo iza, ngaloo ndlela impazamo eguquguqukayo kufutshane ne-resonance frequency yeyona inkulu kwaye iya kubangela ukuba i-stepper motor ilahlekelwe yinyathelo.
Isisombululo:
Ukunciphisa ngokufanelekileyo i-drive current ye-motor stepper; sebenzisa indlela yokuqhuba yokwahlulahlula; sebenzisa iindlela zokumanzisa, kuquka indlela yokumanzisa ngoomatshini. Zonke ezi ndlela zingasentla zinokuphelisa ngempumelelo i-motor oscillation kwaye zigweme into ephuma ngaphandle.
(5) Ukulahlekelwa yintliziyo xa utshintsha indlela
Ingcaciso:
Kuboniswa ukuba ichanile nakweliphi na icala, kodwa iqokelela ukutenxa kamsinya nje yakuba itshintshiwe, yaye okukhona iguqulwa ngakumbi, kokukhona itenxa.
Isisombululo:
Gqirha stepper drive kwicala kunye nemiqondiso ipulse zineemfuno ezithile, ezifana: isalathiso umqondiso kwipulse yokuqala ecaleni komphetho onyukayo okanye edge ehlayo (iimfuno ezahlukeneyo drive azifani) phambi kokufika microseconds ezimbalwa ukuze kumiselwe, kungenjalo kuya kubakho ipulse of i-engile yokusebenza kunye nemfuneko yokwenyani ukujikela kwicala elichaseneyo, kwaye ekugqibeleni ukusilela kukubonakaliswa kancinci i-breakdown ibonakaliswe ngakumbi, isisombululo sisetyenziswa kakhulu kwi-software ukutshintsha ingqiqo yokuthumela i-pulse Isisombululo ngokuyinhloko kukusebenzisa isofthiwe ukuguqula ingqiqo yokuthumela i-pulses okanye ukongeza ukulibaziseka.
(6) Iziphene zeSoftware
Ingcaciso:
Iinkqubo zokulawula zikhokelela kwisinyathelo esilahlekileyo asiqhelekanga, kufuneka uhlolisise inkqubo yokulawula ayikho ingxaki.
Isisombululo:
Awunakufumana unobangela wengxaki okwethutyana, kukho iinjineli eziya kuvumela i-stepper motor ukuba iqhube kangangexesha elithile ukuze iphinde ifumane imvelaphi yekhaya.
