Kodi mphamvu yoyambira ya injini ndi yayikulu bwanji?

Pali malingaliro osiyanasiyana pa kangati poyambira pakali pano pakali pano, ndipo ambiri a iwo amatengera momwe zinthu ziliri.Monga kakhumi, 6 mpaka 8, 5 mpaka 8, 5 mpaka 7 ndi zina zotero.

Chimodzi ndi kunena kuti pamene liwiro la injini ndi zero panthawi yoyambira (ndiko kuti, mphindi yoyamba ya ndondomeko yoyambira), mtengo wamakono panthawiyi uyenera kukhala mtengo wake wotsekedwa.Pamagalimoto omwe amagwiritsidwa ntchito pafupipafupi a Y mndandanda wamagawo atatu asynchronous motors, pali malamulo omveka bwino mu JB/T10391-2002 "Y mndandanda wamagawo atatu asynchronous motors".Pakati pawo, mtengo wotchulidwa wa chiŵerengero cha zokhoma-rotor panopa kwa oveteredwa panopa wa galimoto 5.5kW ndi motere: pa synchronous liwiro 3000, chiŵerengero cha zokhoma-rota panopa kwa oveteredwa panopa ndi 7.0;pa liwiro la synchronous la 1500, chiŵerengero cha zokhoma-rotor panopa ndi panopa oveteredwa ndi 7.0;Pamene liwiro synchronous ndi 1000, chiŵerengero cha zokhoma-rota panopa kwa oveteredwa panopa ndi 6.5;pamene liwiro synchronous ndi 750, chiŵerengero cha zokhoma-rota panopa kwa oveteredwa panopa ndi 6.0.Mphamvu yagalimoto ya 5.5kW ndi yayikulu, ndipo mota yokhala ndi mphamvu yaying'ono ndi chiŵerengero cha poyambira mpaka pano.Iyenera kukhala yaying'ono, kotero mabuku ophunzirira zamagetsi ndi malo ambiri amati kuyambika kwa injini ya asynchronous ndi 4 ~ 7 nthawi yomwe idavoteledwa pakali pano..

Chifukwa chiyani injini imayamba kutsika kwambiri?Pambuyo poyambira panopa ndi yaying'ono?

Apa tikuyenera kumvetsetsa kuchokera kumalingaliro a mfundo yoyambira yamagalimoto ndi mfundo yozungulira yamoto: pomwe injini yolowera ili pamalo oyimitsidwa, kuchokera pamawonekedwe amagetsi, imakhala ngati thiransifoma, ndi mafunde a stator olumikizidwa ndi mphamvu. kuperekera kuli kofanana ndi koyilo yoyamba ya transformer , Kutsekedwa kozungulira kozungulira kozungulira kumakhala kofanana ndi koyilo yachiwiri yachidule ya transformer;kugwirizana kopanda magetsi pakati pa stator winding ndi rotor winding ndi kugwirizana kwa maginito kokha, ndipo maginito a maginito amapanga dera lotsekedwa kupyolera mu stator, mpweya wa mpweya, ndi rotor core.Panthawi yotseka, rotor sinatembenuke chifukwa cha inertia, ndipo mphamvu yozungulira maginito imadula mafunde a rotor pa liwiro lalikulu kwambiri.-Liwiro la synchronous, kotero kuti mafunde a rotor apangitse mphamvu yamagetsi yapamwamba kwambiri.Choncho, kuchuluka kwa magetsi kumayenda mu rotor conductor.Mphamvu yamagetsi, yomwe ilipo imatulutsa mphamvu ya maginito yomwe imalepheretsa mphamvu ya maginito ya stator, monga momwe maginito amtundu wina amasinthira kutulutsa kwamphamvu kwa maginito.Pofuna kusunga maginito oyambirira a maginito kuti agwirizane ndi magetsi panthawiyo, stator imangowonjezera mphamvuyi.Chifukwa chakuti ma rotor panopa ndi aakulu panthawiyi, stator panopa imakulanso kwambiri, ngakhale 4 mpaka 7 nthawi yomwe idavotera panopa.Ichi ndi chifukwa chachikulu choyambira pano.Chifukwa chiyani pano ndi yaying'ono mutangoyamba: Pamene liwiro la galimoto likuwonjezeka, liwiro limene maginito a stator amadula kondakitala wa rotor amachepetsa, mphamvu yamagetsi yamagetsi mu rotor conductor imachepa, ndipo mphamvu yamagetsi mu rotor conductor imachepanso, choncho stator panopa amagwiritsidwa ntchito kuthetsa rotor panopa kwaiye Mbali ya panopa akukhudzidwa ndi maginito flux amachepetsanso, kotero stator panopa kusintha kuchokera lalikulu mpaka laling'ono mpaka yachibadwa.
