Uluhlu olubanzi lwesantya
Iinjini zeStepper zinesantya esikhawulezayo, kwaye isantya semoto sinokutshintshwa ngokuhlengahlengisa isantya sepulse. Oku kuvumela i-stepper motor ukuba iqhelane nezantya ezahlukeneyo zokusebenza kunye neemfuno zomthwalo.
Ukuqalisa Okulungileyo-Yeka kunye neMpendulo ebuyileyo
Iinjini ze-Stepper ziphendula ngokukhawuleza ukulawula iimpawu xa ziqala kwaye zimisa, kwaye zigcine ukuchaneka okuphezulu kunye nokuzinza xa ubuyela umva. Eli nqaku lenza ukuba i-stepper motor ifune ukuqala-ukuyeka rhoqo kwaye ukuguqulwa kwesicelo kunenzuzo.
II, izinto ezingeloncedo kwiinjini ze-stepper
Kulula ukuphulukana nenyathelo okanye ngaphezulu
Ukuba ayilawulwa ngokufanelekileyo, ii-motor stepper zisengozini yokuphuma kwinqanaba okanye ngaphezulu. Ukuphuma-inyathelo kuthetha ukuba i-motor iyasilela ukujikeleza ngokuhambelana nenani elimiselweyo lamanyathelo, ngelixa i-out-of-step ithetha ukuba i-motor ijikeleza ngaphezu kwenani elimiselweyo lamanyathelo. Zombini ezi zinto zibangela ukulahleka kokuchaneka kwesikhundla semoto kwaye zichaphazela ukusebenza kwenkqubo.
Isizukulwana se-out-of-step kunye ne-over-step sinxulumene nezinto ezifana nomthwalo wemoto, isantya sokujikeleza, kunye ne-frequency kunye ne-amplitude yesiginali yokulawula. Ngoko ke, xa usebenzisa ii-motor stepper, ezi zinto kufuneka ziqwalaselwe ngononophelo kwaye kuthathwe amanyathelo afanelekileyo ukuze kugwenywe ukwenzeka kokuphuma kwinqanaba kunye nangaphezulu.
Ubunzima bokufikelela kwizantya eziphezulu zokujikeleza
