Kufotokozera

Iyi ndi mota ya NEMA8 (20mm kukula) yokhala ndi shaft yothamanga, yotchedwa shaft yosagwira.
Mosiyana ndi mota ya stepper yokhala ndi shaft yozungulira/D, shaft iyi yothamanga ndi yaulere kuyenda mmwamba ndi pansi uku ikuzungulira mofanana.
Iyi imadziwika kuti linear stepper motor, yomwe imatha kuyenda molunjika.
Liwiro loyenda molunjika limatsimikiziridwa ndi kuchuluka kwa kayendedwe ka galimoto ndi screw ya lead.
Pali nati yamanja kumbuyo kwa mota, yomwe ingagwiritsidwe ntchito kuzungulira motayo pamanja ikazima, kapena ikhoza kupangidwa ndi ma encoder kuti igwire ntchito mozungulira.

Zokhudza screw ya lead

Chokulungira cha lead chomwe chimagwiritsidwa ntchito pa mota ya hybrid stepper chimakhala mu screw ya lead ya trapezoidal.
Mwachitsanzo pa screw ya Tr3.5*P0.3*1N lead.
Tr imatanthauza mtundu wa screw ya trapezoidal lead
P0.3 imatanthauza kuti pitch ya lead screw ndi 0.3mm
1N imatanthauza kuti ndi screw ya single start lead.
Chokulungira cha lead = nambala yoyambira * phula
Kotero pa screw yeniyeni iyi, ndi lead ya 0.3mm.
Ngodya ya stepper ya mota ya hybrid stepper ndi madigiri 1.8 pa sitepe, zomwe zimatenga masitepe 200 kuti zizungulire kamodzi.
Kutalika kwa sitepe ndi kayendedwe kolunjika komwe injini imapanga, ikatenga sitepe imodzi.
Pa screw ya lead ya 0.3mm, kutalika kwa sitepe ndi 0.3mm/200 sitepe=0.0015mm/sitepe

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.

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

Kapangidwe ka injini kakhoza kusinthidwa kutengera zomwe kasitomala akufuna kuphatikizapo:
M'mimba mwake mwa injini: tili ndi mainchesi 6mm, 8mm, 10mm, 15mm ndi 20 mm.
Kukana kwa coil/ voteji yovomerezeka: kukana kwa coil kumatha kusinthidwa, ndipo ndi kukana kwakukulu, voteji yovomerezeka ya injini imakhala yokwera.
Kapangidwe ka bulaketi/ kutalika kwa sikuru ya lead: ngati kasitomala akufuna kuti bulaketi ikhale yayitali/yaifupi, yokhala ndi kapangidwe kapadera monga mabowo oikira, imatha kusinthidwa.
PCB + zingwe + cholumikizira: Kapangidwe ka PCB, kutalika kwa chingwe ndi malo olumikizira zonse zimatha kusinthidwa, zitha kusinthidwa kukhala FPC ngati makasitomala angafune.

Nthawi yotsogolera

Ngati tili ndi zitsanzo zomwe zilipo, titha kutumiza zitsanzozo mkati mwa masiku atatu.
Ngati tilibe zitsanzo zomwe zilipo, tiyenera kuzipanga, nthawi yopangira ndi pafupifupi masiku 20.
Pakupanga zinthu zambiri, nthawi yotsogolera imadalira kuchuluka kwa oda.

Njira yolipira ndi nthawi yolipira

Kwa zitsanzo, nthawi zambiri timalandira Paypal kapena alibaba.
Pakupanga zinthu zambiri, timalandira malipiro a T/T.
Pa zitsanzo, timasonkhanitsa ndalama zonse tisanapange.
Pakupanga zinthu zambiri, tikhoza kulandira 50% yolipira pasadakhale tisanapange, ndikusonkhanitsa ndalama zotsala 50% tisanatumize.
Tikagwirizana pa oda nthawi zoposa 6, tikhoza kukambirana za malipiro ena monga A/S (titawonana)

FAQ

1. Kodi nthawi yotumizira zitsanzo nthawi zambiri imakhala yayitali bwanji? Kodi nthawi yotumizira maoda akuluakulu a back-end ndi yayitali bwanji?
Nthawi yotsogolera ku oda ya chitsanzo ndi pafupifupi masiku 15, nthawi yotsogolera ku oda yochuluka ndi masiku 25-30.
2. Kodi mumalandira ntchito zomwe zimaperekedwa ndi kasitomala?
Timalandira zinthu zomwe zimasinthidwa kukhala makonda. Kuphatikizapo gawo la injini, mtundu wa waya wotsogola, shaft yotuluka ndi zina zotero.
3. Kodi n'zotheka kuwonjezera cholembera ku injini iyi?
Pa mota yamtunduwu, tikhoza kuwonjezera encoder pa chivundikiro cha mota.
