Stepper lub cev muaj zog tsiv nyob rau hauv me me kauj ruam yog feem ntau qhia nyob ntawm daim ntawv nyob rau hauv degrees. A kauj ruam lub cev muaj zog rau kiv nyob rau hauv ib tug coj ntawm tam sim no yog dhau los ntawm ib tug kauj, ces lwm, ces nyob rau hauv thawj winding ntawm opposite polarity, ces tus thib ob nrog rov qab polarity, kuj. Qhov no ib theem zuj zus yog pheej rov qab ua kev nruam kev sib hloov. Cov kev sib hloov kev taw qhia nyob rau cua, lub "thawj coj", tus "Follower" yog. Cov rov qab kev sib hloov thaum ib tug winding yog ntxeev. Nws yog yuav piv rau lub chaw siv versions rau qhov tam sim no reversal los ntawm qhov chaw siv yog kev cob cog rua rau Vcc thiab txhua kawg ntawm lub kauj yuav raug rho mus rau hauv av qho. Tsis-powered motors yuav tsum tau ib tug tswj voltage bipolar los yog ib tug me ntsis ntau tshaj Circuit Court switching. Thaum lub hwj chim yog thov kom ob tug coils, lub Stepper lub cev muaj zog ntawm ob theem (khoom, feem ntau xa mus rau raws li "ib nrab kauj ruam"). Nyob rau hauv ib nrab-kauj ruam lub tswv yim mus rau lub heev, ib tug yuav thov ob sine tsis nyob rau hauv quadrature rau lub windings thiab rau ib tug heev tus kev sib hloov. Cov txheej txheem no tsis yog tshwj xeeb zoo, txij li thaum lub maub los yuav npaum li cas tsawg zog rau dissipate li lub cav, tab sis yog hais tias tus zoo suab yog tsim nyog, tej zaum yuav muaj nqis ib zaug! Los yog rau cov neeg uas tsis ntshai cov complexity ntawm lub sinusoids yuav approximated nraaj los ntawm kev siv lub nce mus nce los luag hauj lwm mus los. Tab sis lub hom phiaj yog kom tau cov tshuab tawm ntawm lub thawv ntawm qua ntxi, tsis muaj ntau yog vim li cas xav kom lawv yuav tsum nyob ib leeg! Yog li ntawd, ntawm no yog tej yam yooj yim lub tswv yim mus sim.
