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 chomwe maginito okhazikika amatha kukhudzidwa kawiri, osasiyanitsidwa ndi chithandizo champhamvu cha mfundo zaboma kupita ku maginito apamwamba kwambiri okhazikika monga oimira ochita bwino kwambiri, okwera kwambiri othamanga kwambiri amatha kukhala mwachangu. zotchuka kuti zithandize kupulumutsa mphamvu ndi kuchepetsa umuna, kusunga mapiri obiriwira ndi madzi obiriwira.Kupulumutsa mphamvu ndi kuteteza chilengedwe kuyenera kukhala chitukuko chamtsogolo, makamaka m'makampani oyendetsa magalimoto, mawonekedwe osungira maginito amagetsi okhazikika akuwonetsa zabwino zake kuchokera pakupulumutsa mphamvu zake zitha kukhala zapamwamba kuposa 20%, padziko lapansi osowa maginito mphamvu zamagetsi. -zabwino zopulumutsa ndi izi:

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, samafunikira stator kuti apereke 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, maginito okhazikika a synchronous motor pakuchita opaleshoni, pamene katundu amasintha pamene mphamvu yowonjezera mphamvu imakhalabe yosasinthika, galimoto yamtundu wa asynchronous pamene katundu umasintha pamene mphamvu yowonjezera mphamvu idzasintha, injini wamba ya asynchronous pa katunduyo mpaka magawo atatu. za mphamvu yogwira ntchito bwino sizisintha, pamene katunduyo ndi wocheperapo 70% ya mtengo wa mphamvu zake zowonongeka zidzagwa pansi.

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 gawo ili (zokhotakhota kutentha imfa);

2, kugwiritsa ntchito kapangidwe ka brushless, palibe kaboni burashi kapangidwe ka kutayika kwa makina, koma mota ya brushless imadutsa pamagetsi amagetsi kuti azindikire kusintha, apa pali gawo la zida zamagetsi zotayika, ndikusunga kuwonongeka kwamakina poyerekeza. ku chiwonongeko chamtengo wapatali ndi chochepa, kotero gawo la kutayika kwa imfa kuposa kutaya kwa brush motor imfa ndilochepa;

3, kugwiritsa ntchito maginito osowa kwambiri padziko lapansi, mu mphamvu yomweyo yovotera komanso liwiro lovotera, voliyumu yamagalimoto imatha kuchepetsedwa, kupulumutsa pepala lachitsulo la silicon, kuchepetsa gawo lachitsulo.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.
