Chifukwa chiyani maginito okhazikika amapulumutsa mphamvu?

M'zaka zingapo zapitazi, makampani magalimoto pamene mkulu mbiri ya okhazikika maginito Motors, mlingo wa kutchuka limasonyeza chizolowezi kukula. Malinga ndi kusanthula, chifukwa chimene okhazikika maginito Motors akhoza kuwirikiza kawiri nkhawa, osalekanitsidwa ndi thandizo amphamvu a mfundo za boma kuti mkulu-mwachangu okhazikika maginito Motors monga woimira mkulu-mwachangu, kopitilira muyeso mkulu-mwachangu magalimoto galimoto akhoza kutchuka mwamsanga kuthandiza kupulumutsa mphamvu ndi kuchepetsa umuna, kusunga mapiri obiriwira ndi madzi obiriwira. Kupulumutsa mphamvu ndi kuteteza chilengedwe kuyenera kukhala tsogolo lachitukuko, makamaka m'makampani oyendetsa magalimoto, mawonekedwe osungira maginito amagetsi okhazikika akuwonetsa zabwino zake kuchokera pamlingo wake wopulumutsa mphamvu ukhoza kukhala wapamwamba kuposa 20%, padziko lapansi osowa maginito okhazikika maginito mphamvu zopulumutsa mphamvu ndi motere:

Zosowa zapadziko lapansi zokhazikika maginito motor zisanu ndi chimodzi zopulumutsa mphamvu

1, injini yamagetsi yokhazikika kuposa mphamvu yamagetsi wamba yopulumutsa 5% -30%, zida zenizeni zogwirira ntchito zamitundu yosiyanasiyana yopulumutsa mphamvu ndizosiyana.

2, maginito okhazikika a synchronous motor kuti akwaniritse mulingo wamagetsi, mphamvu zamagetsi zopitilira 95%; wamba magawo atatu asynchronous mota ndi mphamvu zamagetsi zitatu, mphamvu zamagetsi zimangokhala 90%.

3, maginito okhazikika a synchronous motor rotor ali ndi chitsulo chosowa padziko lapansi maginito osatha, safuna kuti stator ipereke mphamvu yopatsa mphamvu, kuposa kutayika kwamoto wamba ndikochepa;

4, okhazikika maginito synchronous galimoto stator kutsogolera waya ndi nyenyezi (Y) kugwirizana, akhoza kusunga mphamvu zosasintha panopa ndi yaing'ono; ma mota wamba nthawi zambiri △ kulumikizana;

5, okhazikika maginito synchronous galimoto mu ntchito ndondomeko, pamene katundu kusintha pamene mphamvu mphamvu mphamvu kukhalabe wosasintha, wamba asynchronous galimoto pamene katundu kusintha pamene mphamvu dzuwa mtengo kusintha, wamba asynchronous galimoto mu katunduyo mpaka magawo atatu mwa magawo atatu a mphamvu yogwira ntchito sizisintha, pamene katunduyo ndi wosakwana 70% ya mtengo wake wamagetsi udzagwa molunjika.

6, okhazikika maginito synchronous galimoto palibe katundu panopa ndi yaing'ono, gawo limodzi mwa magawo khumi okha oveteredwa panopa, pamene wamba asynchronous galimoto mu palibe katundu panopa kufika gawo limodzi mwa magawo atatu.

Osowa padziko lapansi okhazikika maginito mota zigawo zikuluzikulu zitatu

1, Osowa dziko lapansi okhazikika maginito galimoto utenga mkulu-ntchito okhazikika maginito, amene amathetsa kukomerera panopa wa stator kapena rotor mbali ya galimoto, choncho kumatha imfa mkuwa wa mbali iyi (zokhotakhota kutentha imfa);

2, kugwiritsa ntchito kapangidwe ka brushless, palibe kaboni burashi ya kutayika kwamakina, koma mota ya brushless imadutsa pamakina amagetsi kuti azindikire kusintha, apa pali gawo la zida zamagetsi zotayika, ndikusunga kutayika kwamakina poyerekeza ndi mtengo wotayika ndi wocheperako, kotero gawo lotayika la kutayika kuposa kutayika kwa burashi yamoto ndi yaying'ono;

3, kugwiritsa ntchito maginito osowa kwambiri padziko lapansi, mu mphamvu yomweyo yovotera komanso liwiro lovotera, voliyumu yamagalimoto imatha kukhala yaying'ono, kupulumutsa pepala lachitsulo la silicon, kuchepetsa kutayika kwachitsulo. Ma motors amphamvu ang'onoang'ono omwe amagwiritsa ntchito maginito osowa padziko lapansi amatha kufikira pafupifupi 90%, ma mota ambiri amakhala pafupifupi 75%.

Kugwiritsa ntchito PMSM kwakhala chizolowezi kwa mabizinesi kupulumutsa mphamvu, kuchepetsa kutulutsa mpweya, komanso kukwaniritsa chitukuko chobiriwira.
