1, Kodi mitundu ya ma miniature stepper motors ndi iti? Kodi makhalidwe awo ndi otani?
Yogawidwa m'magulu atatu kutengera kapangidwe ka rotor. Mtundu wa PM (mtundu wa maginito okhazikika) uli ndi kapangidwe kosavuta, mtengo wotsika kwambiri, ndi ngodya ya sitepe yomwe nthawi zambiri imakhala 7.5 ° kapena 15 °. Ili ndi torque yaying'ono ndipo ndi yoyenera kugwiritsa ntchito monga ma printer ndi ma gimbal a kamera omwe safuna kulondola kwambiri; ma rotor amtundu wa VR (kusafuna kusintha) amapangidwa ndi zinthu zofewa zamaginito zomwe zimakhala ndi resolution yotsika (pafupifupi theka la mtundu wa HB) komanso mawonekedwe osakhalitsa, ndipo tsopano sagwiritsidwa ntchito kawirikawiri; Mtundu wa HB (wosakanizidwa) umaphatikiza zabwino ziwiri zoyambirira, ndi ngodya yofanana ya sitepe ya 1.8 ° kapena 0.9 °, torque yokwera, komanso resolution yapamwamba, zomwe zimapangitsa kuti ikhale chisankho chachikulu cha zida zazing'ono zolondola.
2, Kodi kulondola kwa ngodya ya sitepe ya mota yaing'ono yoyendera masitepe ndi kotani? Kodi zolakwika zidzachulukana?
Kulondola kwa mota ya stepper ndi 3% mpaka 5% ya ngodya ya sitepe ndipo sikumasonkhana. Izi zikutanthauza kuti ngakhale mutagwira ntchito kangapo, zolakwika za sitepe iliyonse sizimasonkhana mpaka pamalo omaliza. Kulondola kwanthawi zonse kwa mota ya hybrid micro stepper ya magawo awiri kumatha kufika 0.18 ° (pa ngodya ya sitepe ya 1.8 °).
3, Kodi injini ya miniature stepper motor ingatulutse mphamvu yochuluka bwanji?
Kutalika kwa ma scope ndi kwakukulu kwambiri. Mphamvu yogwira ya kukula kwa maziko a makina pansi pa 20mm ya mtundu wa PM ikhoza kukhala 0.02N · m; NEMA 8~NEMA 11 (20mm~28mm) nthawi zambiri imayambira pa 0.03~0.1N · m; NEMA 14~NEMA 17 (35mm~42mm) imatha kufika pa 0.2~0.5N · m. Kupitirira 0.8N · m nthawi zambiri kumafuna maziko a NEMA 17 kapena apamwamba, omwe amapitirira gulu la "micro".
4, N’chifukwa chiyani mphamvu ya mota ya stepper imachepa pamene liwiro likuwonjezeka?
Pozungulira, kugwedezeka kwa maginito kumapanga mphamvu yosinthira maginito, ndipo ma frequency akakwera, mphamvu yosinthira maginito imakula, zomwe zimapangitsa kuti mphamvu yamagetsi yosinthira maginito ichepe komanso mphamvu yotulutsa ichepe. Ma mota ang'onoang'ono amakhala ndi ma current current ochepa komanso ma inductance ochepa, zomwe zimapangitsa kuti izi ziwonekere bwino kwambiri pa liwiro lalikulu.
5, Kodi ma micro stepper motors angagwiritsidwe ntchito poyenda molunjika?
Inde. Mota ya stepper yolunjika imalumikiza screw mu rotor ndipo imatulutsa mwachindunji kayendedwe ka mzere, zomwe zimapangitsa kuti pasakhale kufunikira kwa njira zotumizira zakunja. Kugunda kwa ma mota a stepper olunjika ang'onoang'ono nthawi zambiri kumakhala pakati pa 10mm ~ 200mm, ndi mphamvu ya 0.5N ~ 10N. Amagwiritsidwa ntchito kwambiri m'mapampu olowetsa madzi, mapampu olowetsa madzi, ndi zida zazing'ono zopangira opaleshoni.
6, Ndi magawo ati omwe amatsimikiziridwa koyamba posankha mota ya micro stepper?
Choyamba, dziwani mphamvu yoyika katundu ndi malo oikira. Mphamvu yoikira katundu iyenera kukhala yoposa nthawi 1.3 ya mphamvu yeniyeni yoyika katundu. Poganizira kuti ma micro motors ndi osavuta kwambiri kudzaza katundu, tikukulimbikitsani kutenga chitetezo cha nthawi 1.4 mpaka 2. Potsimikizira malo oikira omwe alipo, kukula nthawi zambiri kumakhala choletsa choyamba pazida zazing'ono.
7, Kodi kusiyana kotani pakati pa kusunga mphamvu ndi mphamvu yosinthasintha?
Kusunga mphamvu yamagetsi ndi mphamvu yayikulu kwambiri yomwe mota imatha kusunga ndi mphamvu yamagetsi yoyesedwa ikakhala yosasuntha, kuwonetsa mphamvu yake yosasunthika. Mphamvu yamagetsi ndi mphamvu yeniyeni yotulutsa mphamvu panthawi yogwira ntchito, yomwe imadalira mphamvu yamagetsi yamagetsi panthawi yogwira ntchito ndipo imachepa ndi liwiro lowonjezeka. Posankha, sitingangoyang'ana kwambiri pakusunga mphamvu yamagetsi, tiyenera kuyang'ana pa curve ya torque frequency characteristic curve.
8, Kodi mungasankhe bwanji kukula kwa maziko kutengera torque?
Chidziwitso cha zomwe zachitika: NEMA 8~NEMA 17 ikhoza kusankhidwa pansi pa 0.8N · m; Pansi pa 0.1N · m, NEMA 8~NEMA 11 nthawi zambiri imakhala yokwanira. Muzochitika za micro-application, kufunikira kwa torque nthawi zambiri kumakhala mkati mwa 0.5N · m, ndipo NEMA 14~NEMA 17 ndiye mtundu waukulu.
9, Kodi mungamvetse bwanji mphamvu yamagetsi ya miniature stepper motor?
Mphamvu yoyendetsera (phase current) ndi mtengo wofotokozera wa mphamvu kumapeto onse a kuzunguliridwa kwa gawo limodzi, ndipo si malire enieni. Ikhoza kusinthidwa mozungulira mtengo woyesedwa malinga ndi momwe ntchito ikuyendera, koma kupitirira mtengo woyesedwa kudzawonjezera kutentha, ndipo pansi pa mtengo woyesedwa kungapangitse kuti mphamvu yamagetsi isakwane. Kukana kwa kuzunguliridwa kwa ma micro motors ndi kwakukulu, ndipo mphamvu yoyendetsera yachizolowezi ili pakati pa 0.2 ~ 1.5A.
10, Kodi kufananiza kwa inertia ndikofunikira posankha ma micro stepper motors?
Chofunika kwambiri. Chiŵerengero cha inertia ya katundu ndi inertia ya rotor ya mota ndi chachikulu kwambiri, zomwe zingayambitse kuyankha koyipa kwa mphamvu komanso kutayika kosavuta kwa sitepe panthawi yothamanga. Inertia ya rotor ya micro motor yokha ndi yaying'ono kwambiri, koma inertia yomwe ili kumbali ya katundu (monga screw ndi coupling) ikhoza kukhala yayikulu kwambiri kuposa ya mota yokha, kotero iyenera kuwerengedwa posankha.
