Ama-stepper motorszisebenza ngesimiso sokusebenzisa i-electromagnetism ukuguqula amandla kagesi abe amandla omshini. Iyimoto yokulawula evulekile eguqula izimpawu zokushaya kukagesi zibe ukuhamba kwe-angular noma okuqondile. Isetshenziswa kabanzi kuimboni, izindiza, amarobhothi, ukulinganisa okuncane kanye neminye imikhakha, njengezinsimbi ze-latitude ne-longitude ze-photoelectric zama-satellite abukayo, izinsimbi zempi, ukuxhumana kanye ne-radar, njll. Kubalulekile ukuqonda ama-stepper motors.
Uma kungalayishwa ngokweqile, isivinini semoto, indawo yokumiswa incike kuphela ekuvameni kwesignali ye-pulse kanye nenani lama-pulse, futhi ayithinteki izinguquko emthwalweni.
Uma umshayeli we-stepper ethola isignali ye-pulse, ushayela imoto ye-stepper ukuze ijike indawo yokubuka engaguquki ohlangothini olubekiwe, olubizwa ngokuthi "i-step angle", futhi ukujikeleza kwayo kugijima isinyathelo ngesinyathelo ngendawo yokubuka engaguquki.
Inani lama-pulse lingashintshwa ukuze kulawulwe inani lokufuduka kwe-angular, bese kufinyelelwa inhloso yokuma okunembile; ngesikhathi esifanayo, imvamisa yama-pulse ingashintshwa ukuze kulawulwe isivinini kanye nokusheshisa kokugingqika kwenjini, bese kufinyelelwa inhloso yokulawulwa kwesivinini.
Ngokuvamile i-rotor yemoto iyimagnethi ehlala njalo, lapho ugesi ugeleza ngokugoqa i-stator, ukugoqa i-stator kukhiqiza insimu yamagnetic ye-vector. Le nsimu yamagnetic izoqhuba i-rotor ukuthi ijikeleze indawo yokubuka, ukuze isiqondiso sezinkundla zamagnetic ze-rotor ezimbili sifane nesiqondiso sensimu ye-stator. Lapho insimu ye-vector ye-stator ijikeleza indawo yokubuka eyodwa. I-rotor nayo ilandela le nsimu ngombono owodwa. Kokufaka ngakunye kwe-pulse kagesi, imoto igoqa umugqa owodwa wokubona phambili. Ukufuduka kwe-angular kokukhipha kuhambelana nenani lokufakwa kwe-pulse futhi ijubane lihambisana nemvamisa ye-pulse. Ngokushintsha ukuhleleka kokunika amandla okugoqa, imoto izophenduka. Ngakho-ke ungalawula inani le-pulse, imvamisa kanye nomyalelo wokunika amandla ama-windings emoto esigabeni ngasinye ukulawula ukugoqa kwe-stepper motor.
