Kwindlela eqhelekileyo yokusebenza,imoto ye-stepperihambisa i-engile yenyathelo elinye, oko kukuthi inyathelo elinye ukuya phambili, kwi-pulse nganye yokulawula efunyenweyo. Ukuba ii-pulse zokulawula zifakwa rhoqo, i-motor ijikeleza rhoqo ngokufanelekileyo. I-motor ephuma kwinyathelo ibandakanya inyathelo elilahlekileyo kunye ne-overstep. Xa inyathelo lilahlekile, inani lamanyathelo aqhutywe yi-rotor lingaphantsi kwenani lee-pulse; xa inyathelo liwelwa, inani lamanyathelo aqhutywe yi-rotor lingaphezulu kwenani lee-pulse. Inani lamanyathelo enyathelo elinye elilahlekileyo kunye ne-overstep lilingana ne-integer multiple yenani lee-beats ezibalekayo. Ukulahleka okukhulu kwenyathelo kuya kubangela ukuba i-rotor ihlale kwindawo enye okanye idlidlize ijikeleze indawo enye, kwaye inyathelo elibalulekileyo elidluleyo liya kubangela ukuba i-motor idubule kakhulu.
Ukulahleka kwesizathu senyathelo kunye nesicwangciso
(1) Ukukhawuleziswa kwerotor kucotha kunentsimi yemagnethi ejikelezayo yeimoto ye-stepper
Ingcaciso:
Xa ukukhawuleziswa kwerotor kucotha kunentsimi yemagnethi ejikelezayo yemoto yestepper, oko kukuthi, iphantsi kunesantya sokutshintsha isigaba, imoto yestepper ivelisa ngaphandle kwenyathelo. Oku kungenxa yokungena kwamandla aneleyo kwimoto kwaye i-torque ehambelanayo eveliswa kwimoto yestepper ayivumeli isantya serotor ukuba silandele isantya sokujikeleza sentsimi yemagnethi yestator, ngaloo ndlela ibangela ukuphuma kwenyathelo. Ekubeni i-torque eguquguqukayo yemoto yestepper iyancipha njengoko isantya sokusebenza okuqhubekayo sinyuka, naliphi na isantya sokusebenza esiphezulu kuneso siya kuvelisa inyathelo elilahlekileyo. Oku kulahleka kwenyathelo kubonisa ukuba imoto yestepper ayinayo i-torque eyaneleyo kwaye ayinawo amandla okutsala aneleyo.
Isisombululo:
a. Yenza i-torque ye-electromagnetic eveliswa yi-stepping motor ngokwayo inyuke. Oku kungaba kuluhlu lwangoku olulinganisiweyo ukuze kwandiswe umsinga wokuqhuba; kuluhlu lwamaxesha aphezulu e-torque akwanelanga, ungaphucula i-drive voltage yesekethe yokuqhuba; tshintsha usebenzise i-torque enkulu yokunyathela i-torque, njl. b, ukuze i-stepping motor ifune ukoyisa i-torque incitshiswe. Oku kungenziwa ngokunciphisa ngokufanelekileyo i-frequency yokusebenza kwe-motor ukuze kwandiswe i-output torque ye-motor; ukuseta ixesha elide lokukhawulezisa ukuze i-rotor ifumane amandla aneleyo.
(2) Isantya esiqhelekileyo serotor siphezulu kunesantya esiqhelekileyo sokujikeleza kwentsimi yemagnethi ye-stator
Ingcaciso:
Isantya esiqhelekileyo serotor siphezulu kunesantya esiqhelekileyo sokujikeleza kwe-stator magnetic field, xa i-stator inikwa amandla kwaye ivuselelwe ixesha elide kunexesha elifunekayo ukuze irotor inyathele phambili, ke irotor ifumana amandla amaninzi ngexesha lenkqubo yokunyathela, nto leyo eyenza i-output torque eveliswa yi-stepping motor inyuke, nto leyo ebangela ukuba i-motor inyathele ngaphezulu. Xa i-stepping motor isetyenziselwa ukuqhuba ezo ndlela zenza umthwalo unyuke uye phezulu, kunokwenzeka ukuba ivelise i-overstep, nto leyo ebangelwa kukuba i-torque efunekayo yi-motor iyancipha xa umthwalo uhla.
Isisombululo:
Nciphisa umsinga wokuqhuba wemoto yokunyathela ukuze unciphise i-torque yokukhupha yemoto yokunyathela.
(3) Ukungabi namandlaimoto yokunyathelakunye nomthwalo ewuthwalayo
Ingcaciso:
Ngenxa yokungasebenzi kakuhle kwemoto yokunyathela kunye nomthwalo ewuthwalayo, imoto ayinakuqalwa kwaye ayimiswa kwangoko ngexesha lokusebenza, kodwa inyathelo elilahlekileyo liyenzeka ngexesha lokuqalisa kwaye inyathelo elingaphezulu liyenzeka ngexesha lokuma.
Isisombululo:
Ngokusebenzisa inkqubo yokukhawulezisa nokunciphisa isantya, oko kukuthi, ukuqala ngesantya esiphantsi, uze ukhawulezise kancinci kancinci ukuya kwisantya esithile, uze ukhawulezise kancinci kancinci ude uyeke. Ukukhawulezisa okufanelekileyo nokugudileyo kunye nolawulo lokuncitshiswa kwesantya ngundoqo wokuqinisekisa ukusebenza okuthembekileyo, okusebenzayo nokuchanekileyo kwenkqubo yokuqhuba i-stepper.
(4) Isandi semoto yokunyathela
Ingcaciso:
I-Resonance nayo yimbangela yokungaqhubeki kakuhle. Xa i-stepper motor isebenza ngokuqhubekayo, ukuba i-frequency ye-control pulse ilingana ne-intrinsic frequency ye-stepper motor, i-resonance iya kwenzeka. Kwixesha elinye le-control pulse, i-vibration ayinciphi ngokwaneleyo, kwaye i-pulse elandelayo iyafika, ngoko ke i-dynamic error ekufutshane ne-resonance frequency yeyona inkulu kwaye iya kubangela ukuba i-stepper motor ilahlekelwe yi-step.
Isisombululo:
Nciphisa ngokufanelekileyo i-drive current ye-stepper motor; sebenzisa indlela yokwahlulahlula i-subdivision drive; sebenzisa iindlela zokunciphisa ubushushu, kuquka nendlela yokunciphisa ubushushu ngoomatshini. Zonke ezi ndlela zingasentla zinokuphelisa ngempumelelo ukushukuma kwe-motor kwaye ziphephe isiganeko sokuphuma kwinqanaba elithile.
(5) Ukulahlekelwa yintliziyo xa utshintsha indlela
Ingcaciso:
Kuboniswa ukuba ichanekile nakweyiphi na indlela, kodwa iqokelela ukuphambuka kwangoko nje ukuba indlela itshintshe, kwaye okukhona itshintsha amaxesha amaninzi, kokukhona iphambuka ngakumbi.
Isisombululo:
I-general stepper drive kwicala kunye nemiqondiso ye-pulse ineemfuno ezithile, ezinje: indlela yomqondiso kwi-pulse yokuqala ecaleni komda onyukayo okanye umda owelayo (iimfuno ze-drive ezahlukeneyo azifani) ngaphambi kokufika kwe-microseconds ezimbalwa eziza kugqitywa, kungenjalo kuya kubakho i-pulse ye-engile yokusebenza kunye nesidingo sokwenyani sokujika kwicala elichaseneyo, kwaye ekugqibeleni isenzeko sokungaphumeleli sibonakala kokukhona uhamba uthambekele ngakumbi, kokukhona ukuqhekeka kuncinci kucaca ngakumbi, isisombululo sisetyenziswa kakhulu kwisoftware ukutshintsha ingqiqo yokuthumela i-pulse. Isisombululo ikakhulu kukusebenzisa isoftware ukutshintsha ingqiqo yokuthumela ii-pulse okanye ukongeza ukulibaziseka.
(6) Iziphene zesoftware
Ingcaciso:
Iinkqubo zolawulo ezikhokelela kwinyathelo elilahlekileyo aziqhelekanga, kufuneka ujonge inkqubo yolawulo ukuba ayiyongxaki.
Isisombululo:
Andikwazi ukufumana unobangela wengxaki okwethutyana, kukwakho neenjineli eziza kuvumela i-stepper motor ukuba isebenze ixesha elithile ukuze iphinde ifumane imvelaphi yayo.
