Iimoto ze-stepperzisebenza ngomgaqo wokusebenzisa i-electromagnetism ukuguqula amandla ombane abe ngamandla oomatshini. Yimoto yokulawula evulekileyo eguqula imiqondiso yepulse yombane ibe zii-angular okanye ii-linear displacements. Isetyenziswa kakhulu kwiimboni, inqwelo-moya, iirobhothi, umlinganiselo ocolekileyo kunye nezinye iindawo, ezifana nezixhobo ze-photoelectric latitude kunye ne-longitude zesathelayithi ezijongayo, izixhobo zomkhosi, unxibelelwano kunye ne-radar, njl. Kubalulekile ukuqonda ii-stepper motors.
Kwimeko yokungalayishi kakhulu, isantya semoto, indawo yokumiswa ixhomekeke kuphela kwimvamisa yesignali ye-pulse kunye nenani lee-pulses, kwaye ayichaphazeleki lutshintsho kumthwalo.
Xa umqhubi we-stepper efumana isignali ye-pulse, uqhuba i-stepper motor ukuba ijikelezise indawo eqingqiweyo yokujonga kwicala elimiselweyo, elibizwa ngokuba yi-"step angle", kwaye ukujikeleza kwayo kuqhutywa inyathelo ngenyathelo ngenqanaba elimiselweyo lokujonga.
Inani leepulse linokuguqulelwa ukulawula ubungakanani bokufuduka kwe-angular, uze ufikelele kwinjongo yokuma ngokuchanekileyo; kwangaxeshanye, ukuphindaphinda kweepulse kunokwenziwa ukulawula isantya kunye nokukhawulezisa kwe-motor rolling, uze ufikelele kwinjongo yokulawula isantya.
Ngokwesiqhelo i-rotor yemoto yimagnethi esisigxina, xa umbane udlula kwi-stator winding, i-stator winding ivelisa i-vector magnetic field. Le magnethi iya kuqhuba i-rotor ukuba ijikeleze indawo yokujonga, ukuze ulwalathiso lwesibini see-magnetic field ze-rotor lufane nolwalathiso lwentsimi ye-stator. Xa intsimi ye-vector ye-stator ijikeleza indawo yokujonga. I-rotor ikwalandela le ndawo ngombono omnye. Kwi-electrical pulse input nganye, i-motor iqengqeleka umgca omnye wokubona phambili. Ukuhanjiswa kwe-angular kwemveliso kuhambelana nenani le-pulses input kwaye isantya sihambelana ne-frequency ye-pulses. Ngokutshintsha ulandelelwano lwe-winding energisation, i-motor iya kujika. Ngoko unokulawula inani le-pulses, i-frequency kunye nomyalelo wokunika amandla ii-motor windings kwisigaba ngasinye ukulawula ukuqengqeleka kwe-stepper motor.
