1. Menenestepper motor?
Motocin Stepper suna tafiya daban da sauran injina. Motocin stepper na DC suna amfani da motsi mai katsewa. Akwai ƙungiyoyin coil da yawa a cikin jikinsu, ana kiran su "phases", waɗanda za a iya juya su ta kunna kowane lokaci a jere. Mataki daya a lokaci guda.
Ta hanyar sarrafa motar motsa jiki ta hanyar mai sarrafawa / kwamfuta, zaku iya matsayi daidai a madaidaicin gudu. Saboda wannan fa'idar, ana amfani da injinan stepper akai-akai a cikin kayan aikin da ke buƙatar madaidaicin motsi.
Motocin Stepper suna da girma dabam dabam, siffofi da ƙira. Wannan labarin zai bayyana musamman yadda za a zabi wani stepper motor bisa ga bukatun.
2. Menene amfaninstepper Motors?
A. Matsayi- Saboda motsi na stepper Motors daidai ne kuma mai maimaitawa, ana iya amfani da su a cikin nau'ikan samfuran sarrafawa iri-iri, kamar bugu na 3D, CNC, dandamali na kyamara, da sauransu, wasu rumbun kwamfyutoci kuma suna amfani da mataki Motor don sanya shugaban karantawa.
B. Gudanar da sauri- Madaidaicin matakai kuma suna nufin cewa zaku iya sarrafa saurin jujjuyawa daidai, dacewa don aiwatar da takamaiman ayyuka ko sarrafa robot.
C. Ƙarƙashin gudu da ƙaƙƙarfan ƙarfi- Gabaɗaya, motocin DC suna da ƙananan juzu'i a ƙananan gudu. Amma stepper Motors suna da matsakaicin karfin juyi a ƙananan gudu, don haka suna da kyakkyawan zaɓi don aikace-aikacen madaidaicin ƙananan sauri.
3. Lalacewarstepper motor :
A. Rashin iya aiki- Ba kamar injinan DC ba, yawan amfani da injinan stepper ba shi da alaƙa da nauyi. Lokacin da ba su yin aiki, akwai har yanzu ta hanyar, don haka yawanci suna da matsalolin zafi, kuma ingancin ya fi ƙasa.
B. Torque a babban gudun- yawanci karfin juyi na stepper motor a babban gudun yana ƙasa da ƙarancin gudu, wasu injinan na iya samun kyakkyawan aiki a babban saurin, amma wannan yana buƙatar mafi kyawun tuƙi don cimma wannan tasirin.
C. Rashin iya saka idanu- Motoci na yau da kullun ba za su iya ba da amsa / gano matsayi na yanzu na motar ba, muna kiran shi "buɗe madauki", idan kuna buƙatar kulawar "rufe madauki", kuna buƙatar shigar da encoder da direba, don ku iya Kulawa / sarrafa daidaitaccen juyawa na motar a kowane lokaci, amma farashin yana da girma sosai kuma bai dace da samfuran talakawa ba.
Matakin Matafiya
4. Rarraba takawa:
Akwai da yawa iri stepper Motors, dace da daban-daban yanayi.
Koyaya, a ƙarƙashin yanayi na al'ada, ana amfani da injin PM da matasan stepper gabaɗaya ba tare da la'akari da injunan sabar uwar garken masu zaman kansu ba.
5. Girman Motoci:
La'akari na farko lokacin zabar mota shine girman motar. Motocin Stepper sun fito ne daga ƙananan injuna 4mm (an yi amfani da su don sarrafa motsin kyamarori a cikin wayoyin hannu) zuwa behemoths kamar NEMA 57.
Motar tana da jujjuyawar aiki, wannan juzu'in yana ƙayyade ko zai iya biyan buƙatun ku na ƙarfin motar.
Misali: Ana amfani da NEMA17 gabaɗaya a cikin firintocin 3D da ƙananan kayan aikin CNC, kuma ana amfani da manyan injin NEMA wajen kera masana'antu.
NEMA17 a nan yana nufin diamita na waje inci 17 ne, wanda shine girman tsarin inci, wanda shine 43cm idan aka canza shi zuwa centimita.
A kasar Sin, gabaɗaya muna amfani da santimita & millimeters don auna girma, ba inci ba.
6. Yawan matakan mota:
Adadin matakan kowane juyi na mota yana ƙayyade ƙudurinsa da daidaito. Motocin Stepper suna da matakai daga 4 zuwa 400 a kowace juyin juya hali. Yawancin lokaci ana amfani da matakai 24, 48 da 200.
Ana bayyana daidaito yawanci azaman matakin kowane mataki. Alal misali, mataki na 48-mataki mota ne 7.5 digiri.
Duk da haka, da drawbacks na high daidaici ne gudu da kuma karfin juyi. A daidai wannan mita, gudun madaidaicin injuna ya ragu.
7. Akwatin Gear:
Wata hanya don inganta daidaito da juzu'i shine amfani da akwatin gear.
Misali, akwatin gear 32: 1 na iya canza motar mai mataki 8 zuwa injin daidaitaccen mataki mai mataki 256, yayin da yake kara karfin da sau 8.
Amma za a rage saurin fitarwa daidai da kashi ɗaya bisa takwas na asali.
Karamin mota kuma zai iya cimma tasirin babban juzu'i ta wurin raguwar gearbox.
8. Shafi:
Abu na ƙarshe da kuke buƙatar la'akari shine yadda ake daidaita mashin ɗin motar da yadda ake daidaita tsarin tuƙi.
Nau'in shafts sune:
Zagaye shaft / D shaft: Wannan nau'in shaft shine mafi daidaitattun kayan fitarwa, ana amfani da su don haɗa abubuwan jan hankali, saitin kaya, da dai sauransu. Ƙaƙwalwar D ya fi dacewa da babban juyi don hana zamewa.
Gear shaft: Kayan fitarwa na wasu injina kayan aiki ne, wanda ake amfani dashi don dacewa da takamaiman tsarin kayan aiki.
Screw shaft: Ana amfani da motar da ke da shingen dunƙulewa don gina injin kunnawa na linzamin kwamfuta, kuma ana iya ƙara maɗaukaki don cimma ikon sarrafa layin.
Da fatan za a ji kyauta don tuntuɓar mu idan kuna sha'awar kowane injin ɗin mu.
