Ma stepper motor ndi mtundu wamba wagalimoto womwe umatha kuzungulira kutsogolo ndi kumbuyo. Kusintha mawaya kumatanthauza kusintha kulumikizidwa kwa mphamvu ya mota ya stepper kuti isinthe momwe imayendera. Pali njira zambiri zosinthira mawaya, ndipo imodzi mwa njira zofala zosinthira mawaya ifotokozedwa mwatsatanetsatane pansipa.
Ma stepper motor ndi mtundu wapadera wa mota womwe umatha kuzunguliridwa mokhazikika. Ikhoza kutembenuzidwira kutsogolo ndi kubwerera kumbuyo mwa kusintha polarity ya magetsi kapena njira yomwe ikuyenda panopa. Makina a stepper nthawi zambiri amakhala ndi ma koyilo awiri kapena anayi, pomwe koyilo iliyonse imayendetsedwa ndi mphamvu yamagetsi.
Mfundo yofunikira ya njira yosinthira waya ndikusintha dongosolo lamayendedwe apano kudzera pamakoyilo, ndikusintha komwe kumayendera kwa stepper motor poyambitsa ma coils mwanjira ina. Njira yodziwika yosinthira mawaya mu injini ya mawaya anayi ikufotokozedwa mwatsatanetsatane pansipa.
Choyamba, ndikofunikira kumvetsetsa momwe ma coils a stepper motor amapangidwira. Ma motors a Stepper nthawi zambiri amakhala ndi zozungulira ziwiri zoyandikana, iliyonse imakhala ndi cholumikizira. Mu injini ya mawaya anayi muli ma coil awiri otchedwa "A" ndi "B". Koyilo iliyonse ili ndi ma terminals awiri olembedwa "A1", "A2" ndi "B1", "B2". Ma terminals awa adzalumikizidwa ndi magetsi kuti atsegule injini.
Munjira iyi yosinthira mawaya, tigwiritsa ntchito mawaya awiri amagetsi, otchedwa "Vcc" ndi "Gnd" kuyendetsa galimoto ya stepper. Ma Stepper motors nthawi zambiri amafunikira wowongolera (monga dalaivala kapena microcontroller) kuti aziwongolera kulumikizana kwamagetsi.
Gawo 1: Lumikizani "A1" kuti "Vcc" ndi "A2" kuti "B1". Pankhaniyi, chingwe magetsi ndi motere: "Vcc" - "A1" - "A2" - "B1" - "Gnd". - Ndi".
Gawo 2: Lumikizani "B2" kuti "Vcc" ndi kusagwirizana "A1". Panthawi imeneyi, kugwirizana magetsi ndi motere: "Vcc" - "B2" - "A2" - "B1" - "Gnd". - Ndi".
Gawo 3: Lumikizani "A2" kuti "Vcc" ndi kusagwirizana "B1". Panthawi imeneyi, kugwirizana magetsi ndi motere: "Vcc" - "B2" - "A2" - "Gnd".
Khwerero 4: Lumikizani "B2" ndikulumikizanso "A2" ndi "A1". Panthawi imeneyi, mizere magetsi ndi motere: "Vcc" - "A1" - "Gnd".
Mwa kulumikiza chingwe chamagetsi molingana ndi masitepe omwe ali pamwambapa, kutembenuka kwa kutsogolo ndi kumbuyo kwa stepper motor kumatha kuzindikirika. Choyamba, ndikofunikira kuwonetsetsa kuti chingwe chamagetsi chikulumikizidwa bwino kuti tipewe mabwalo amfupi ndi kuwonongeka kwina kwamagetsi. M'pofunikanso kuonetsetsa kuti chingwe mphamvu akhoza kupereka panopa zokwanira kuyendetsa galimoto stepper.
Ndikofunika kuzindikira kuti njira yosinthira waya kwa ma stepper motors imatha kusiyanasiyana kutengera mtundu wamoto komanso wopanga. Choncho, pogwiritsira ntchito stepper motor, tikulimbikitsidwa kuti tiyang'ane ku bukhu laumisiri la injini kapena malangizo a wopanga kuti atsimikizire kuti njira yoyenera yosinthira waya ikugwiritsidwa ntchito.
Mwachidule, njira yosinthira mawaya a stepper ndi njira yopititsira patsogolo ndi kubweza mozungulira mozungulira posintha dongosolo la kulumikizana kwaposachedwa ndi ma koyilo. Mwa kulumikiza zingwe zamagetsi m'njira zosiyanasiyana, dongosolo lomwe ma coil a motor stepper amayatsidwa amatha kusinthidwa, motero kusintha komwe kumayendera. Mukamagwira ntchito yosinthira waya ya stepper motor, ndikofunikira kuti muwerenge mosamala buku laukadaulo la injini kapena malangizo a wopanga ndikuwonetsetsa kuti zingwe zamagetsi zimalumikizidwa bwino komanso zomwe zilipo.
