Poyerekeza ndi ma asynchronous motors, maginito okhazikika a synchronous motors ali ndi zabwino zambiri zodziwikiratu.Ma motors okhazikika a maginito omwe ali ndi ma synchronous motors ali ndi zinthu zambiri monga mphamvu yayikulu, chilozera choyendetsa bwino, kukula kochepa, kulemera pang'ono, kutentha pang'ono, ndi zina zambiri. ku mphamvu ya gridi yamagetsi yomwe ilipo, ndikusunga ndalama za gridi yamagetsi.
Kuchita bwino komanso kufananiza kwamphamvu
Asynchronous galimoto mu ntchito, ndi rotor mapiringidzo kuyamwa mbali ya mphamvu kuchokera gululi chisangalalo, kotero kuti mowa wa gululi mphamvu, mbali iyi ya mphamvu mpaka mapeto apano mu rotor mapiringidzo mu kutentha anadya, nkhani imfa pafupifupi 20-30% ya kutayika kwathunthu kwagalimoto, komwe kumabweretsa kutsika kwachangu kwagalimoto.Kukokera kwa rotor yomwe imasinthidwa kukhala mafunde a stator ndi inductive pano, kotero kuti mafunde akumapeto a stator akutsalira kumbuyo kwa voteji ya gululi, zomwe zimapangitsa kuchepa kwa mphamvu yamagalimoto.
Kuphatikiza apo, asynchronous motor mu katundu factor (= P2 / Pn) <50%, magwiridwe ake ogwiritsira ntchito komanso mphamvu zogwiritsira ntchito mphamvu zimatsika kwambiri, motero zimafunikira kuti zizigwira ntchito m'malo azachuma, ndiye kuti, kuchuluka kwa 75% - 100%.
Okhazikika maginito synchronous galimoto mu rotor ophatikizidwa mu maginito okhazikika, maginito okhazikika kukhazikitsa rotor maginito munda, mu ntchito yachibadwa, ozungulira ndi stator maginito synchronous ntchito, palibe anachititsa panopa mu rotor, palibe kutayika rotor kukana, ndi chimodzi chokha chomwe chingathe kusintha mphamvu ya injini ndi 4% mpaka 50%.Panthawi imodzimodziyo, chifukwa palibe kulowetsedwa kwamakono mu rotor ya injini yokhazikika ya maginito synchronous motor, stator yokhotakhota ikhoza kukhala yopingasa katundu, kotero kuti mphamvu ya galimotoyo imakhala pafupifupi 1. Permanent maginito synchronous motor pa mlingo wa katundu. > 20%, mphamvu zake zogwirira ntchito komanso mphamvu zogwiritsira ntchito zokhala ndi kusintha pang'ono, komanso magwiridwe antchito ndi> 80%.
Kuyambira torque
Asynchronous motor kuyambira, galimotoyo imayenera kukhala ndi torque yayikulu yoyambira, koma ndikuyembekeza kuti poyambira siikulu kwambiri, kuti isapange kutsika kwamagetsi ochulukirapo mugululi ndikukhudza magwiridwe antchito amtundu wina wamagetsi ndi zida zamagetsi zolumikizidwa. ku gridi.Kuonjezera apo, pamene choyambira chimakhala chachikulu kwambiri, galimoto yokhayo imakhala ndi mphamvu yowonjezereka yamagetsi, ngati nthawi zambiri imayamba, pali ngozi yowotcha ma windings.Chifukwa chake, mapangidwe oyambira asynchronous motor nthawi zambiri amakumana ndi vuto.
Permanent maginito synchronous motor angagwiritsidwenso ntchito asynchronous poyambira mode, chifukwa chanthawi zonse maginito synchronous motor ntchito yanthawi zonse ya rotor makhota sikugwira ntchito, mu kapangidwe ka okhazikika maginito mota, makhoti a rotor amatha kupangidwa kuti akwaniritse zofunikira za mkulu kuyambira makokedwe Mwachitsanzo, kuti kuyambira makokedwe multiplier ndi asynchronous galimoto 1.8 nthawi 2.5, kapena kuposa, njira yabwino kwa zida ochiritsira mphamvu, Iwo bwino amathetsa chodabwitsa cha "akavalo aakulu kukoka galimoto yaing'ono".t” m’zida zamagetsi wamba.
Ntchitokukwera kwa kutentha
Monga asynchronous galimoto ntchito, ndi koloko yokhota mafunde otaya panopa, ndipo panopa ndi kwathunthu mu mawonekedwe a matenthedwe matenthedwe matenthedwe, kotero mu koloko yokhotakhota adzatulutsa kuchuluka kwa kutentha, kotero kuti kutentha kwa galimoto kukwera, zomwe zimakhudza kwambiri. moyo utumiki wa galimoto.
Ponena za injini yokhazikika ya maginito synchronous motor, chifukwa champhamvu kwambiri ya injini yamagetsi yokhazikika, palibe kukana kutayika mumayendedwe a rotor, pali zochepa kapena pafupifupi palibe zotakataka mumayendedwe a stator, kotero kuti kukwera kwamoto kwamoto kumakhala kochepa. , zomwe zimawonjezera moyo wautumiki wa injini.
Mphamvu pakugwiritsa ntchito gridi
Chifukwa cha mphamvu yochepa ya injini ya asynchronous motor, galimotoyo imayenera kuyamwa mphamvu zambiri zowonongeka kuchokera ku gridi yamagetsi, zomwe zimapangitsa kuti pakhale mphamvu zambiri zowonongeka mu gridi yamagetsi, zida zotumizira ndi kusintha ndi zida zopangira magetsi, motero khalidwe la kuchepa kwa gridi yamagetsi, zomwe sizimangowonjezera katundu wa gridi yamagetsi ndi zida zotumizira ndi kusintha ndi zida zopangira magetsi, panthawi imodzimodziyo, zowonongeka zamakono zimadya mbali ya mphamvu yamagetsi mu gridi yamagetsi, kufalitsa ndi zida zosinthira ndi zida zopangira magetsi, zomwe zimapangitsa kuti pakhale kuchepa kwachangu komanso kukhudza grid yamagetsi amagetsi.Panthawi imodzimodziyo, mphamvu yowonongeka imagwiritsa ntchito mbali ya mphamvu yamagetsi mu gridi yamagetsi, zipangizo zotumizira ndi kusintha ndi zida zopangira magetsi, zomwe zimapangitsa kuti gululi likhale lopanda mphamvu komanso limakhudza kugwiritsa ntchito mphamvu zamagetsi.Momwemonso, chifukwa cha kuchepa kwamphamvu kwa ma asynchronous motors, kuti akwaniritse kufunikira kwa mphamvu zotulutsa, ndikofunikira kutenga mphamvu zambiri kuchokera pagululi, motero kukulitsa kutayika kwa mphamvu zamagetsi ndikuwonjezera katundu pagululi.
Ndipo kwa okhazikika maginito synchronous motor, rotor yake popanda kulowetsedwa kwaposachedwa, mphamvu yamagalimoto ndipamwamba, zomwe sizimangowonjezera mtundu wa gululi, kotero kuti gululi siliyeneranso kukhazikitsa zida zolipirira mphamvu zamagetsi.Kuphatikiza apo, chifukwa chakuchita bwino kwambiri kwa injini yokhazikika ya maginito synchronous, imapulumutsanso mphamvu ya gululi
Anhui Mingteng Permanent-Magnetic Machinery&Electrical Equipment Co., Ltd.idakhazikitsidwa mu 2007 ndipo ndi amodzi mwa opanga koyambirira ku China kuti apange ndikupanga ma mota amagetsi okhazikika.Ili ndi R&D yokwanira, kupanga, kugulitsa, ndi gulu lazogulitsa pambuyo pake.Kampaniyo nthawi zonse imatsatira luso lodziyimira pawokha ndikutsata mfundo zamakampani za "zogulitsa zapamwamba, kasamalidwe ka kalasi yoyamba, mautumiki apamwamba, ndi mtundu woyamba", kukonza njira zopulumutsira maginito okhazikika amagetsi opulumutsa mphamvu kwa ogwiritsa ntchito. , ndi kuyesetsa kukhala mtsogoleri ndi muyezo setter mu osowa padziko lapansi okhazikika maginito makampani galimoto China.
