1. Menenemotar stepper?
Motocin stepper suna motsawa daban-daban fiye da sauran injina. Motocin stepper na DC suna amfani da motsi mara ci gaba. Akwai ƙungiyoyin coil da yawa a jikinsu, waɗanda ake kira "phases", waɗanda za a iya juyawa ta hanyar kunna kowane mataki a jere. Mataki ɗaya bayan ɗaya.
Ta hanyar sarrafa motar stepper ta hanyar na'urar sarrafawa/kwamfuta, za ka iya sanya ta daidai a daidai gudun. Saboda wannan fa'idar, galibi ana amfani da injin stepper sosai a cikin kayan aiki waɗanda ke buƙatar motsi daidai.
Motocin Stepper suna da girma dabam-dabam, siffofi da ƙira daban-daban. Wannan labarin zai yi bayani musamman kan yadda ake zaɓar motar stepper bisa ga buƙatunku.
2. Menene fa'idodininjinan stepper?
A. Matsayi- Saboda motsi na injinan stepper daidai ne kuma maimaituwa ne, ana iya amfani da su a cikin samfuran da aka sarrafa daidai, kamar bugawa ta 3D, CNC, dandamalin kyamara, da sauransu, wasu rumbunan hard drives kuma suna amfani da step Motor don sanya kan karatu.
B. Sarrafa gudu- matakai masu daidai kuma suna nufin cewa zaku iya sarrafa saurin juyawa daidai, wanda ya dace da yin takamaiman ayyuka ko sarrafa robot
C. Ƙaramin gudu da ƙarfin juyi mai yawa- Gabaɗaya, injinan DC suna da ƙarancin ƙarfin juyi a ƙananan gudu. Amma injinan stepper suna da matsakaicin ƙarfin juyi a ƙananan gudu, don haka zaɓi ne mai kyau don aikace-aikacen ƙananan gudu masu inganci.
3. Rashin amfanimotar stepper :
A. Rashin inganci- Ba kamar injinan DC ba, yawan amfani da injinan stepper ba shi da alaƙa da nauyin da ake buƙata. Idan ba sa aiki, har yanzu akwai wutar lantarki ta hanyar, don haka yawanci suna da matsalolin zafi fiye da kima, kuma ingancinsa ya fi ƙasa.
B. Karfin juyi a babban gudu- yawanci karfin injin stepper a babban gudu yana ƙasa da na ƙaramin gudu, wasu injinan har yanzu suna iya samun ingantaccen aiki a babban gudu, amma wannan yana buƙatar ingantaccen tuƙi don cimma wannan tasirin
C. Ba a iya sa ido ba- injinan stepper na yau da kullun ba za su iya ba da amsa / gano matsayin motar a halin yanzu ba, muna kiransa "buɗe madauki", idan kuna buƙatar sarrafa "rufe madauki", kuna buƙatar shigar da mai shigar da bayanai da direba, don ku iya Kulawa / sarrafa madaidaicin juyawar motar a kowane lokaci, amma farashin yana da yawa kuma bai dace da samfuran yau da kullun ba
Matakin Mota na Matakai
4. Rarraba matakai:
Akwai nau'ikan injinan stepper da yawa, waɗanda suka dace da yanayi daban-daban.
Duk da haka, a cikin yanayi na yau da kullun, galibi ana amfani da injinan PM da injinan stepper masu haɗin gwiwa ba tare da la'akari da injinan sabar masu zaman kansu ba.
5. Girman Mota:
Abu na farko da za a yi la'akari da shi wajen zabar injin shine girman injin. Injinan Stepper sun kama daga ƙananan injinan 4mm (wanda ake amfani da su don sarrafa motsin kyamarori a cikin wayoyin komai da ruwanka) zuwa ƙananan injinan kamar NEMA 57.
Motar tana da karfin juyi mai aiki, wannan karfin juyi yana tantance ko zai iya biyan bukatarka ta karfin juyi.
Misali: Ana amfani da NEMA17 gabaɗaya a cikin firintocin 3D da ƙananan kayan aikin CNC, kuma ana amfani da manyan injinan NEMA a cikin samar da masana'antu.
NEMA17 a nan tana nufin diamita na waje na injin shine inci 17, wanda shine girman tsarin inci, wanda shine 43cm lokacin da aka canza shi zuwa santimita.
A ƙasar Sin, galibi muna amfani da santimita da milimita don auna girma, ba inci ba.
6. Adadin matakan mota:
Adadin matakai a kowace juyin mota yana ƙayyade ƙudurinsa da daidaitonsa. Injinan Stepper suna da matakai daga 4 zuwa 400 a kowace juyin. Yawanci ana amfani da matakai 24, 48 da 200.
Yawanci ana bayyana daidaito a matsayin matakin kowane mataki. Misali, matakin injin mai matakai 48 shine digiri 7.5.
Duk da haka, rashin kyawun daidaiton aiki shine gudu da karfin juyi. A daidai wannan mita, saurin injunan da ke da daidaiton aiki ya yi ƙasa.
7. Akwatin kaya:
Wata hanyar inganta daidaito da karfin juyi ita ce amfani da akwatin gearbox.
Misali, akwatin gear mai lamba 32: 1 zai iya canza injin mai matakai 8 zuwa injin daidaitacce mai matakai 256, yayin da yake ƙara ƙarfin juyi sau 8.
Amma saurin fitarwa zai ragu zuwa kashi ɗaya bisa takwas na ainihin.
Ƙaramin mota kuma zai iya cimma tasirin babban ƙarfin juyi ta hanyar akwatin ragewa.
8. Shaft:
Abu na ƙarshe da ya kamata ka yi la'akari da shi shine yadda za ka daidaita shaft ɗin motar da kuma yadda za ka daidaita tsarin tuƙinka.
Nau'ikan shafts sune:
Shaft mai zagaye / Shaft mai D: Wannan nau'in shaft shine shaft mafi daidaitaccen fitarwa, wanda ake amfani da shi don haɗa pulleys, gear sets, da sauransu. Shaft ɗin D ya fi dacewa da ƙarfin juyi mai ƙarfi don hana zamewa.
Shaft ɗin gear: Shaft ɗin fitarwa na wasu injina gear ne, wanda ake amfani da shi don daidaita takamaiman tsarin gear.
Shaft ɗin sukurori: Ana amfani da injin da ke da shaft ɗin sukurori don gina mai kunna layi, kuma ana iya ƙara zamiya don cimma ikon sarrafawa ta layi
Da fatan za a iya tuntuɓar mu idan kuna sha'awar kowane ɗayan injinan stepper ɗinmu.
