1.General kuumbwa kwe stepper motor open-loop servo system
Iyo armature yekumisa uye yekudzima nguva yeinotsika mota uye simba-pakutevedzana kwechikamu chega chega inoona inobuda angular displacement uye mafambiro.Iyo yekudzora pulse kugovera frequency inogona kuwana yekumhanyisa kutonga kweinotsika mota.Naizvozvo, iyo stepper mota control system inowanzo tora yakavhurika-loop control.
2.Hardware kutonga kwe stepper motor
Iyo inotsika mota inotenderedza inoenderana nhanho kona pasi pechiito che pulse, sekureba imwe nhamba yemapulses ichidzorwa, iyo inoenderana kona iyo inotsika mota inotenderera inogona kudzorwa nemazvo.Nekudaro, iwo mahwindi emota inotsika anofanirwa kupihwa simba mune imwe kurongeka kuti ishande nemazvo.Iyi nzira yekugadzira mota ichivhurika nekudzima zvinoenderana nekutonga kwemapurusi ekuisa inonzi ring pulse distribution.
Pane nzira mbiri dzekuwana kugoverwa kwedenderedzwa.Imwe ndeyekugovera software yekombuta.Tafura yekutarisa kana nzira yekuverenga inoshandiswa kuita kuti mapini matatu ekubuda ekombuta aite sequentially kuburitsa denderedzwa rekuparadzira pulse siginecha inosangana nekumhanya uye negwara zvinodiwa.Iyi nzira inogona kushandisa zvizere komputa software zviwanikwa kudzikisa mutengo wehardware, kunyanya kupararira kwepulse kwema-multi-phase motors kunoratidza zvakanakira.Nekudaro, nekuti iyo software inomhanya inotora nguva yekumhanya kwekombuta, iyo yakazara nguva yekududzira basa ichawedzera, izvo zvinokanganisa kumhanya kweiyo stepper mota.
Imwe yacho ndeye Hardware mhete kugovera, iyo inoshandisa dhijitari maseketi kuvaka kana yakakosha kugovera mhete michina kugadzirisa inoenderera mberi pulse masaini uye kubuda mhete pulses mushure mekugadzirisa wedunhu.Mhete dzinogovanisa dzakavakwa nemaseketi edhijitari dzinowanzo sanganisira zvinhu zvakasiyana (senge flip-flops, logic gedhi, nezvimwewo), izvo zvinoratidzwa nehukuru hukuru, mutengo wakakwira, uye kusavimbika.
