Ubwino nthawi zambiri umatchulidwa ndipo nthawi zambiri umatchedwa cliché, ndipo ngakhale utagwiritsidwa ntchito ngati buzzword, mainjiniya ambiri amachotsa lingalirolo asanayang'ane zomwe zikuchitika.Kampani iliyonse ikufuna kugwiritsa ntchito mawuwa, koma ndi angati omwe ali okonzeka kuwagwiritsa ntchito?Ubwino ndi malingaliro ndi njira yamoyo.Quality n'zosavuta kunena, koma mu nkhani iyi ndi chinachake chimene chingafotokozedwe pa sitepe iliyonse ya kamangidwe.Ubwino, choyamba, uyenera kutengedwa mozama kuyambira pamwamba mpaka pansi.Zogulitsa zamagalimoto zoyenerera zimafunikira chisamaliro: mtundu, kubweretsa, ndi mtengo (panthawi yopangira), ndipo ngati mumayang'ana kwambiri mtengo, mumatha kupatsa makasitomala zinthu zabwino kwambiri popanda ukadaulo wopitilira muyeso.Izi zikutanthauza kuti pali yankho losavuta lomwe ndi losavuta kupanga ndikubweretsa.Zidutswa zonse ziyenera kuphatikizidwa ndipo wogulitsa magalimoto ayenera kumvetsetsa cholinga ndi cholinga cha mapangidwe a wogwiritsa ntchito.
Makina owongolera amkati mwa ogulitsa magalimoto nthawi zambiri amagwiritsa ntchito njira ya 4.5 sigma, ndipo 6 sigma si njira yokhutiritsa pazomwe makasitomala amakumana nazo kuchokera kuzinthu zawo.Pokhapokha poyang'anira khalidwe labwino ndizomwe angatsimikizire kuti chinthucho chikufunika, osati pakupanga mapangidwe.Ndi dongosololi wogwiritsa ntchito amapeza "motor yomwe nthawi zonse komanso modalirika imakwaniritsa zofunikira pa moyo wa galimotoyo".Cholinga ichi ndi chofunikira kwambiri pakupanga kwamphamvu kwambiri, komwe mizere yonse yamagulu imatha kuyima mosavuta chifukwa cha zolakwika zazinthu.Kuti atsimikizire mtundu wa ma stepper motors a kampaniyo, amayang'ana magawo atatu ofunikira, mtundu wagawo, mawonekedwe apangidwe komanso mtundu wopanga.
Kusankhidwa kwa othandizira kumathandiza kwambiri pakupulumuka ndi chitukuko cha makampani opanga mota ndi kupanga, ndipo ndi gawo lofunikira pakuwongolera kasamalidwe kamene kamafunika.Poganizira za khalidwe lachigawo, njira yopangira zinthu imaphatikizapo zigawo zingapo: stators, rotor, shafts, bearings, end caps, windings, lead, connectors, ndi zina.Komanso, msonkhano uliwonse waung'ono ukhoza kugawidwa m'magulu ang'onoang'ono monga mawaya, kusungunula, nyumba ndi zisindikizo, zolumikizira, etc. zonse zikhale zapamwamba kwambiri kotero kuti chomaliza chidutsa.
Kwa ma motors, kulondola kwapang'onopang'ono ndi kukhazikika kwa rotor, stator ndi zotsekera zomaliza ndizofunikira kwambiri, kukulitsa njira yodutsamo kudutsa ma stator ndi mano a rotor ndikuchepetsa kukayikira.Pachifukwa ichi, kusiyana kwa mpweya kapena kusiyana pakati pa rotor ndi stator kuyenera kukhala kochepa.Kuchepa kwa kusiyana kwa mpweya, kumachepetsa danga lolakwika la chipangizocho.Izi zikuwoneka zosavuta kuzimvetsetsa, koma ngati zigawo ziwiri kapena zonse ziwiri sizikukhazikika bwino, zomwe zimapangitsa kuti mpweya usavutike kumapangitsa kuti ntchitoyo isagwirizane.Muzovuta kwambiri, ngati kukhudzana kumachitika, injini imakhala yopanda ntchito.
Rotor inertia imakhudza magwiridwe antchito onse a motor stepper. Low inertia rotor amatha kuyankha mwachangu ndikupatsa ogwiritsa ntchito kuthamanga kwambiri komanso torque yapamwamba kwambiri. Kupanga koyenera komaliza kumatsimikizira kuchuluka kwamkati mkati komwe kumayikidwa mu rotor yayikulu.Zovala zomaliza zimakhala ndi udindo wowongolera bwino rotor.Kuwongolera molakwika kumatha kukhudza kwambiri mtundu wa chinthu chomaliza, ndipo kusalumikizana bwino kwa rotor kungayambitse mipata yosagwirizana ndi mpweya ndikupangitsa kugwira ntchito molakwika.
Kusakanikirana kosagwirizana kumeneku kumalipidwa ndi kuonjezera kukula kwa kusiyana kwa mpweya pakati pa rotor ndi stator, kuchepetsa mwayi wa kukhudzana kwawo.Izi ndizovomerezeka pakuchotsa zolakwika zokha.Njirayi imalepheretsa kwambiri kugwira ntchito kwa ma stepper motors, ndipo kusiyana kwakukulu pakati pa magawo, kumapangitsa kuti ntchitoyo ikhale yosagwirizana.Ngakhale kusintha kwakung'ono kumatha kukhala ndi zotsatira zazikulu pa inertia, kukana, inductance, kutulutsa kwamphamvu kwa torque ndi resonance (kugwedezeka kosafunikira).Mapangidwe a rotor ndi ofunika kwambiri kuti apititse patsogolo ntchito ya galimotoyo, rotor iyenera kusonyeza maginito okwanira pamene imakhalabe yopepuka momwe mungathere kuti muchepetse inertia ya rotor.
Stator ikhoza kusinthidwa molingana ndi cholinga chomaliza cha kapangidwe kake: kulondola kwakukulu, kusalala kapena kutulutsa kwamphamvu kwambiri, ndipo mapangidwe amitengo amatsimikizira kuchuluka kwa zinthu zokhotakhota zomwe zingagwirizane ndi mizati ya stator.Komanso, kuchuluka kwa mizati nthawi zambiri 8, 12 kapena 16 kumalumikizana ndi kulondola komanso kutulutsa kwa torque ya mota.Shaft iyenera kukhala yolimba mokwanira kuti ipirire mobwerezabwereza ma torque ndi mphamvu za axial popanda kupindika kapena kuwonongeka pakapita nthawi.Momwemonso, zonyamula ziyenera kufanana ndi magwiridwe antchito komanso nthawi yamoyo ya chinthu chomaliza.Monga chigawo chomwe chimatsimikizira moyo wamagalimoto, mayendedwe nthawi zambiri amakhala ovala kwambiri.
Zigawo zina zofunika kwambiri zimaphatikizapo zipewa zomaliza, zomwe zimagwira ma berelo ndikuwonetsetsa kulumikizana koyenera pakati pa stator ndi rotor.Ma bearings nawonso amafunika kukhala apamwamba kwambiri kuti asamalire ndikuwonetsetsa kuti ma stepper motor azikhala ndi moyo wautali.Mlongoti uliwonse umakhala ndi maginito amagetsi, zomwe zimafunikira kuti pakhale mafunde osasinthasintha pamtengo uliwonse pogwiritsa ntchito waya wapamwamba kwambiri womwe ulipo.Kusiyanasiyana kwa mainchesi a waya kungayambitse vuto la kusinthasintha kwa ma torque, zomwe zimapangitsa kuti ma torque achuluke, kumveka bwino kapena kugwedezeka, komanso kusasunthika bwino kwa chinthu chomaliza.
Pomaliza
Momwe mungasankhire ogulitsa apamwamba kwambiri komanso opambana pamafunika njira zowunikira zowunikira komanso zida zowunikira zowerengera kuti zithandizire kuwongolera magwiridwe antchito ndikulimbikitsa chitukuko chamakampani opanga magalimoto.Kuti muwonetsetse kuti ma motors akuyenda bwino, mota iliyonse imayesedwa isanatumizidwe kuti ikwaniritse zofunikira zamagetsi (kukana, inductance, kutayikira pakalipano), ma torque (kugwira ndi kuyimitsa torque), makina amakina (kuwonjezedwa kwa axle yakutsogolo ndi kutalika kwa thupi) ndi zina. zinthu zapadera.
