Pofuna kupititsa patsogolo ubwino wa galimoto, m'zaka zaposachedwa, phokoso la galimoto laphatikizidwa mu chimodzi mwa zizindikiro zowunikira khalidwe, makamaka kwa malo ogwiritsira ntchito galimoto komanso kukhudzana ndi anthu pafupi ndi zomwe zikuchitika, phokoso la galimoto lakhala ngati zofunikira kwambiri zowunika.
Kuti muzitha kulamulirainjini ya asynchronousphokoso, kuwonjezera pa mapangidwe a stator ndi rotor slot ndi kusankha koyenera kwa stator ndi rotor slot kupatulapo slant slot ingagwiritsidwe ntchito pofuna kuchepetsa phokoso lamagetsi lamagetsi la galimoto. Koma ndendende kuchuluka kwa malo otsetsereka komwe kuli koyenera, kuyezetsa kwina kumafunika kuti mutsimikizire.
Kawirikawiri, malo otsetsereka a rotor asynchronous motors akhoza kutengedwa ngati phula limodzi la dzino la stator, lomwe lingathenso kukwaniritsa zofunikira. Komabe, kuti mupititse patsogolo phokoso lagalimoto, ndikofunikira kufufuza malo otsetsereka otsetsereka, omwe amafunikira mawerengedwe ambiri ndi kutsimikizira.
Kuwunikiridwa kuchokera pamalingaliro opanga, kupanga mowongoka kagawo ka mota ndikukonza kukhala kosavuta, koma ngati kuli kofunikira, ndikofunikira kukhala stator slot kapena rotor slot torsion. The stator slot torsion ndizovuta, choncho, nthawi zambiri, rotor slot tilting. Rotor slot torsion nthawi zambiri kudzera pa shaft processing torsion ya keyway kuti mukwaniritse, mabizinesi apamwamba kwambiri a zida, kugwiritsa ntchito kukhomerera kozungulira, munjira yopangira ma rotor pachimake kuti mukwaniritse.
Phokoso la electromagnetic zimayambitsa ndi njira zopewera
Phokoso lagalimoto nthawi zonse lakhala vuto lovuta kulithetsa, limapangidwa makamaka ndi ma elekitirodi, makina, mpweya wabwino pazifukwa zitatu. Phokoso la electromagnetic mu motor asynchronous ndi chifukwa cha mafunde a stator ndi rotor mu mpweya wa mpweya womwe umakhazikitsidwa mu harmonic magnetic field interaction ndi electromagnetic force wave chifukwa cha kugwedezeka kwa goli, kukakamiza ozungulira.kugwedezeka kwa mpweyandi opangidwa. Choyambitsa chachikulu ndi chifukwa cha malo osayenera, stator ndi rotor eccentricity kapena mpweya wochepa kwambiri.
Phokoso la electromagnetic limayamba chifukwa cha kugwedezeka kwa maginito komwe kumapangitsa kusintha kwa nthawi ndi malo ndipo kumachitika ndi magawo osiyanasiyana a mota. Chifukwa chake, kwa ma asynchronous motors, zomwe zimapangitsa kuti phokoso la ma elekitiromu likhale ndi:
● Mafunde a mphamvu ya radial mu danga la mpweya maginito amapangitsa kusintha kwa ma radial ndi kugwedezeka kwanthawi ndi nthawi kwa stator ndi rotor.
● Mafunde amphamvu amphamvu amphamvu kwambiri amphamvu yamphamvu ya maginito akugwira ntchito pa stator ndi rotor cores, zomwe zimachititsa kuti mafunde asokonezeke komanso kugwedezeka nthawi ndi nthawi.
● Kusintha kwa ma harmonics osiyanasiyana a stator core kumakhala ndi maulendo osiyanasiyana amkati, ndipo resonance imayamba pamene mafunde amphamvu a radial ali pafupi kapena ofanana ndi amodzi mwa mafunde apakati pakatikati.
Kupindika kwa stator kumapangitsa kuti mpweya wozungulira uzigwedezeka, ndipo phokoso lalikulu la ma elekitiromu ndi phokoso la katundu.
Pakatikati pamakhala, gawo lachitatu la harmonic limachulukitsidwa, ndipo phokoso lamagetsi limawonjezeka.
Malo otsetsereka a stator ndi rotor onse ali otseguka, ndipo pali "mafunde otsegula" ambiri omwe amapangidwa pansi pa mphamvu ya mafunde amphamvu mu mpweya wa maginito, ndi kuchepa kwa mpweya, kufalikira kwa mipata, kukulirakulira kwake.
Pofuna kupewa vutoli, ofesi mu mapangidwe siteji ya mankhwala kudzera njira zina zothandiza kusintha, monga: kusankha wololera maginito kusinthasintha kachulukidwe, kusankha yoyenera mapiringidzo mtundu ndi chiwerengero cha misewu kugwirizana, kuwonjezera chiwerengero cha stator. kukhomerera mipata, kuchepetsa harmonic kugawa koyenera wa ma windings stator, processing yoyenera ya stator-rotor mpweya gap galimoto, kusankha stator ndi ozungulira poyambira ndi ozungulira kolowera poyambira, ntchito rotor, ndi zina zenizeni miyeso.
