1. Kodistepper mota?
Ma mota a Stepper amayenda mosiyana ndi ma mota ena. DC stepper motors ntchito discontinuous movement. Pali magulu angapo a coil m'matupi awo, otchedwa "magawo", omwe amatha kuzunguliridwa poyambitsa gawo lililonse motsatizana. Gawo limodzi panthawi.
Poyang'anira stepper motor kudzera pa controller / kompyuta, mutha kuyika molondola pa liwiro lenileni. Chifukwa cha mwayiwu, ma stepper motors nthawi zambiri amagwiritsidwa ntchito kwambiri pazida zomwe zimafunikira kuyenda bwino.
Ma motors a Stepper ali ndi makulidwe osiyanasiyana, mawonekedwe ndi mapangidwe. Nkhaniyi ifotokoza mwatsatanetsatane momwe mungasankhire stepper mota malinga ndi zosowa zanu.
2. Ubwino wake ndi chiyanima stepper motors?
A. Kuyika- Chifukwa mayendedwe a ma stepper motors ndi olondola komanso obwerezabwereza, amatha kugwiritsidwa ntchito pazinthu zosiyanasiyana zoyendetsedwa bwino, monga kusindikiza kwa 3D, CNC, nsanja ya kamera, ndi zina zambiri, ma hard drive ena amagwiritsanso ntchito step Motor poyika mutu wowerengedwa.
B. Kuwongolera liwiro- masitepe olondola amatanthauzanso kuti mutha kuwongolera liwiro la kuzungulira, koyenera kuchita ndendende kapena kuwongolera maloboti
C. Liwiro lochepa komanso torque yayikulu- Nthawi zambiri, ma mota a DC amakhala ndi torque yotsika pama liwiro otsika. Koma ma stepper motors ali ndi torque yayikulu pa liwiro lotsika, ndiye kuti ndi chisankho chabwino pamapulogalamu otsika kwambiri othamanga kwambiri.
3. Kuipa kwastepper mota :
A. Kusachita bwino- Mosiyana ndi ma mota a DC, kugwiritsa ntchito ma stepper motors sikukhudzana kwambiri ndi katundu. Pamene sakugwira ntchito, pamakhalabe pompopompo, choncho nthawi zambiri amakhala ndi vuto la kutentha kwambiri, ndipo magwiridwe antchito amakhala otsika kwambiri.
B. Torque pa liwiro lalikulu- nthawi zambiri ma torque a stepper motor pa liwiro lalitali amakhala otsika kuposa liwiro lotsika, ma mota ena amathabe kuchita bwino pa liwiro lalikulu, koma izi zimafunikira kuyendetsa bwino kuti mukwaniritse izi.
C. Kulephera kuyang'anira- Wamba ma stepper motors sangathe kuyankha / kuzindikira momwe galimoto ilili, timayitcha "loop lotseguka", ngati mukufuna "kutsekeka" kuwongolera, muyenera kuyika encoder ndi dalaivala, kuti mutha kuyang'anira / kuwongolera kuzungulira kwagalimoto nthawi iliyonse, koma mtengo wake ndi wokwera kwambiri ndipo siwoyenera pazinthu wamba.
Magawo Oyenda Magalimoto
4. Gulu la makwerero:
Pali mitundu yambiri ya ma stepper motors, oyenera pazinthu zosiyanasiyana.
Komabe, nthawi zonse, ma motors a PM ndi ma hybrid stepper motors amagwiritsidwa ntchito mosaganizira ma seva achinsinsi.
5. Kukula kwagalimoto:
Chinthu choyamba kuganizira posankha galimoto ndi kukula kwa galimotoyo. Ma Stepper motors amachokera ku 4mm miniature motors (yomwe imagwiritsidwa ntchito kuwongolera kayendedwe ka makamera mu mafoni a m'manja) mpaka ma behemoth ngati NEMA 57.
Motor ili ndi torque yogwira ntchito, torque iyi imatsimikizira ngati ingakwaniritse zomwe mukufuna mphamvu zamagalimoto.
Mwachitsanzo: NEMA17 imagwiritsidwa ntchito kwambiri mu osindikiza a 3D ndi zida zazing'ono za CNC, ndipo ma motors akulu a NEMA amagwiritsidwa ntchito popanga mafakitale.
NEMA17 apa akutanthauza m'mimba mwake akunja injini ndi 17 mainchesi, umene ndi kukula kwa inchi dongosolo, amene ndi 43cm pamene kutembenuzidwa kukhala centimita.
Ku China, timagwiritsa ntchito masentimita & mamilimita kuyeza kukula, osati mainchesi.
6. Chiwerengero cha masitepe agalimoto:
Kuchuluka kwa masitepe pakusintha kwagalimoto kumatsimikizira kutsimikizika kwake ndi kulondola kwake. Ma Stepper motors ali ndi masitepe kuchokera ku 4 mpaka 400 pakusintha. Nthawi zambiri masitepe 24, 48 ndi 200 amagwiritsidwa ntchito.
Kulondola nthawi zambiri kumafotokozedwa ngati mlingo wa sitepe iliyonse. Mwachitsanzo, sitepe ya 48-step motor ndi madigiri 7.5.
Komabe, zovuta za kulondola kwambiri ndi liwiro komanso torque. Pafupipafupi, kuthamanga kwa ma motors olondola kwambiri ndi otsika.
7. Bokosi la zida:
Njira ina yowonjezerera kulondola komanso torque ndikugwiritsa ntchito bokosi la gear.
Mwachitsanzo, bokosi la gear 32: 1 limatha kusintha mota ya masitepe 8 kukhala mota yolondola masitepe 256, ndikuwonjezera torque nthawi 8.
Koma liwiro lotulutsa lidzakhala lochepetsedwa kukhala gawo limodzi mwa magawo asanu ndi atatu a choyambirira.
Galimoto yaying'ono imathanso kukwaniritsa mphamvu ya torque yayikulu kudzera mu gearbox yochepetsera.
8. Shaft:
Chinthu chomaliza chomwe muyenera kuganizira ndi momwe mungagwirizanitse shaft ya galimoto ndi momwe mungagwirizane ndi kayendetsedwe kanu.
Mitundu ya shafts ndi:
Round shaft / D shaft: Mtundu uwu wa shaft ndiyomwe umatuluka kwambiri, womwe umagwiritsidwa ntchito polumikiza ma pulleys, ma gear seti, ndi zina zotere.
Shaft ya giya: Shaft yotulutsa ma motors ena ndi giya, yomwe imagwiritsidwa ntchito kufananiza ndi zida zinazake
Screw shaft: Mota yokhala ndi screw shaft imagwiritsidwa ntchito kupanga cholumikizira mzere, ndipo chowongolera chitha kuwonjezeredwa kuti chiwongolere mzere.
Chonde khalani omasuka kulumikizana nafe ngati mukufuna ma stepper motors athu.
