Motar stepper wani nau'in mota ne na kowa wanda ke da ikon jujjuya gaba da juyawa. Canza wayoyi yana nufin canza haɗin wutar lantarki na injin stepper don canza alkiblarsa. Akwai hanyoyi daban-daban na canza wayoyi, kuma ɗayan hanyoyin gama gari na canza wayoyi za a yi cikakken bayani a ƙasa.
Motar stepper wani nau'in mota ne na musamman wanda zai iya jujjuya shi a madaidaicin kusurwar mataki. Ana iya juya shi gaba da baya ta hanyar canza polarity na samar da wutar lantarki ko alkiblar kwararar yanzu. Motar stepper yawanci tana kunshe da coils biyu ko hudu, inda kowace na'ura ke tuka ta da wutar lantarki.
Babban ka'idar hanyar canza waya ita ce canza tsari na halin yanzu ta hanyar coils, da canza yanayin motsi na motar stepper ta hanyar kunna coils a cikin wani tsari na daban. Hanyar gama gari ta canza wayoyi a cikin injin stepper mai waya huɗu an kwatanta dalla-dalla a ƙasa.
Da fari dai, wajibi ne a fahimci tsarin da aka shirya coils na stepper motor. Motocin Stepper yawanci sun ƙunshi coils biyu kusa da su, kowanne da tasha. A cikin motar stepper mai waya hudu, akwai coils biyu, ana kiran su coil "A" da coil "B". Kowane nada yana da tashoshi biyu masu lakabin "A1", "A2" da "B1", "B2". Za a haɗa waɗannan tashoshi zuwa wutar lantarki don kunna motar.
A cikin wannan hanyar na sauya wayoyi, za mu yi amfani da wayoyi biyu masu amfani da wutar lantarki, masu lakabin "Vcc" da "Gnd" don fitar da motar stepper. Motocin Stepper yawanci suna buƙatar mai sarrafawa (kamar direba ko microcontroller) don sarrafa haɗin wutar lantarki.
Mataki 1: Haɗa "A1" zuwa "Vcc" da "A2" zuwa "B1". A wannan yanayin, layin samar da wutar lantarki shine kamar haka: "Vcc" - "A1" - "A2" - "B1" - "Gnd". - Gnd".
Mataki 2: Haɗa "B2" zuwa "Vcc" kuma cire haɗin "A1". A wannan gaba, haɗin wutar lantarki shine kamar haka: "Vcc" - "B2" - "A2" - "B1" - "Gnd". - Gnd".
Mataki 3: Haɗa "A2" zuwa "Vcc" kuma cire haɗin "B1". A wannan gaba, haɗin wutar lantarki shine kamar haka: "Vcc" - "B2" - "A2" - "Gnd".
Mataki 4: Cire haɗin "B2" kuma sake haɗa "A2" da "A1". A wannan lokaci, layin samar da wutar lantarki sune kamar haka: "Vcc" - "A1" - "Gnd".
Ta hanyar haɗa kebul na wutar lantarki bisa ga matakan da ke sama, za a iya gane jujjuyawar gaba da juyawa na injin stepper. Da fari dai, wajibi ne a tabbatar da cewa an haɗa igiyar wutar lantarki daidai don guje wa gajerun da'irori da sauran lahani ga kewayen motar. Hakanan wajibi ne don tabbatar da cewa igiyar wutar lantarki za ta iya samar da isasshen halin yanzu don fitar da injin stepper.
Yana da mahimmanci a lura cewa hanyar canza waya don masu motsi na stepper na iya bambanta dangane da takamaiman ƙirar motar da masana'anta. Don haka, lokacin da ake aiki da injin stepper, ana ba da shawarar a koma ga jagorar fasaha na injin ko umarnin masana'anta don tabbatar da cewa an yi amfani da hanyar canza waya daidai.
Don taƙaitawa, hanyar canza waya ta stepper mota hanya ce ta gaba da jujjuyawar motar ta hanyar canza tsarin haɗin yanzu zuwa coils. Ta hanyar haɗa igiyoyin wutar lantarki ta hanyoyi daban-daban, ana iya canza tsarin da aka kunna coils na stepper, don haka canza yanayin motsi na motar. Lokacin yin aikin canza waya ta stepper motor, wajibi ne a karanta littafin fasaha na injin ko umarnin masana'anta kuma tabbatar da cewa an haɗa igiyoyin wutar lantarki da kyau kuma an ba da isassun halin yanzu.
