Zokhudza mota wa hybrid stepper

Ma mota oyendera ma stepper osakanikirana ali ndi mawonekedwe a sikweya, ndipo mota yoyendera ma stepper imatha kuzindikirika ndi mawonekedwe ake apadera akunja.
Mota yoyendera hybrid stepper ili ndi ngodya ya 1.8°step （200 step/revolution） kapena ngodya ya 0.9°step (masitepe 400/revolution). Ngodya ya step imatsimikiziridwa ndi nambala ya dzino pa rotor's laminations.

Pali njira zingapo zotchulira injini ya hybrid stepper:
Ndi gawo la Metric (gawo: mm) kapena ndi gawo la Imperial (gawo: inchi)
Mwachitsanzo, mota ya 42mm = mota ya stepper ya mainchesi 1.7.
Choncho mota ya 42mm ingathenso kutchedwa mota ya NEMA 17.

Kufotokozera dzina la injini ya hybrid stepper:
Mwachitsanzo, mota ya stepper ya 42HS40:
42 ikutanthauza kuti kukula kwake ndi 42mm, kotero ndi mota ya NEMA17.
HS amatanthauza mota ya Hybrid Stepper.
40 amatanthauza kutalika kwa mota ndi 40mm.
Tili ndi kutalika kosiyana komwe makasitomala angasankhe, ndi kutalika kwakukulu, mota imakhala ndi mphamvu yayikulu, kulemera kwakukulu, komanso mtengo wokwera.
Apa pali kapangidwe ka mkati mwa mota wamba wosakanizidwa.

Kugwiritsa ntchito mota ya Hybrid stepper

Chifukwa cha mphamvu ya injini ya hybrid stepper (masitepe 200 kapena 400 pa kuzungulira), imagwiritsidwa ntchito kwambiri pa ntchito zomwe zimafuna kulondola kwambiri, monga:
Kusindikiza kwa 3D
Kulamulira mafakitale (CNC, makina opukutira okha, makina opangira nsalu)
Zipangizo zamakompyuta
Makina opakira
Ndi machitidwe ena odziyimira okha omwe amafunikira kulamulira kolondola kwambiri.

Zolemba zokhudza ma mota oyendera ma hybrid stepper

Makasitomala ayenera kutsatira mfundo ya "kusankha ma stepper motors kaye, kenako kusankha dalaivala kutengera ma stepper motors omwe alipo kale"
Ndibwino kuti musagwiritse ntchito njira yoyendetsera galimoto yonse poyendetsa mota yoyendera yosakanikirana, ndipo kugwedezeka kumakhala kwakukulu mukayendetsa galimoto yonse.
Mota ya Hybrid stepper ndiyoyenera kwambiri pamasewera otsika liwiro. Tikupangira kuti liwiro lisapitirire 1000 rpm (6666PPS pa madigiri 0.9), makamaka pakati pa 1000-3000PPS (ma digiri 0.9), ndipo ikhoza kulumikizidwa ndi gearbox kuti ichepetse liwiro lake. Motayo imagwira ntchito bwino kwambiri komanso phokoso lochepa pafupipafupi yoyenera.
Chifukwa cha zifukwa zakale, mota yokhala ndi voteji ya 12V yokha ndi yomwe imagwiritsa ntchito 12V. Voltage ina yovomerezeka pakupanga kapangidwe si voteji yoyenera kwambiri pagalimoto. Makasitomala ayenera kusankha voteji yoyenera yoyendetsera ndi dalaivala woyenera kutengera zomwe akufuna.
Ikagwiritsidwa ntchito mota ndi liwiro lalikulu kapena katundu wambiri, nthawi zambiri siimayamba ndi liwiro logwira ntchito mwachindunji. Tikupangira kuti pang'onopang'ono muwonjezere ma frequency ndi liwiro. Pazifukwa ziwiri: Choyamba, motayo sitaya masitepe, ndipo chachiwiri, imatha kuchepetsa phokoso ndikuwonjezera kulondola kwa malo.
Mota siyenera kugwira ntchito pamalo ogwedera (osakwana 600 PPS). Ngati iyenera kugwiritsidwa ntchito pang'onopang'ono, vuto la kugwedera lingachepe posintha magetsi, mphamvu yamagetsi kapena kuwonjezera damping.
Pamene mota ikugwira ntchito pansi pa 600PPS (madigiri 0.9), iyenera kuyendetsedwa ndi mphamvu yamagetsi yaying'ono, inductance yayikulu komanso mphamvu yamagetsi yochepa.
Pa katundu wokhala ndi nthawi yayikulu ya inertia, mota yayikulu iyenera kusankhidwa.
Ngati pakufunika kulondola kwambiri, zitha kuthetsedwa powonjezera gearbox, kuwonjezera liwiro la injini, kapena kugwiritsa ntchito divisionionation driving. Komanso mota ya magawo 5 (unipolar motor) ingagwiritsidwe ntchito, koma mtengo wa makina onse ndi wokwera mtengo, kotero sigwiritsidwa ntchito kawirikawiri.

Kukula kwa mota ya stepper:
Pakadali pano tili ndi ma mota a 20mm(NEMA8), 28mm(NEMA11), 35mm(NEMA14), 42mm(NEMA17), 57mm(NEMA23), 86mm(NEMA34). Tikukulimbikitsani kuti muyambe mwasankha kukula kwa mota, kenako mutsimikizire zina, mukasankha mota ya hybrid stepper.

Utumiki Wosintha Zinthu

Timapereka ntchito yosinthira makina pa injini kuphatikizapo nambala ya waya wa lead (ma waya 4/ma waya 6/ma waya 8), kukana kwa coil, kutalika kwa chingwe ndi mtundu wake, komanso tili ndi kutalika kosiyanasiyana komwe makasitomala angasankhe.
Shaft yotulutsa nthawi zonse ndi D shaft, ngati makasitomala akufuna screw shaft ya lead, timapereka chithandizo chosintha pa lead screws, ndipo mutha kusintha mtundu wa lead screw ndi kutalika kwa shaft.
Chithunzi chili pansipa ndi mota ya hybrid stepper yokhala ndi screw ya trapezoidal lead.
