Ma mota amphamvu kwambiri amapanga korona, chifukwa chiyani ma mota osinthasintha amabala korona?

Korona imayamba chifukwa cha mphamvu yamagetsi yosalingana yomwe imapangidwa ndi ma conductor osalingana. Mozungulira mphamvu yamagetsi yosalingana komanso pafupi ndi elekitirodi yokhala ndi radius yaying'ono yokhota, pamene mphamvu yamagetsi ikukwera kufika pamlingo winawake, kutuluka kwa mpweya kudzachitika chifukwa cha mpweya womasuka, zomwe zimapangitsa korona.

Kuchokera ku mikhalidwe yopangira korona, titha kupeza kuti minda yamagetsi yosalingana, ma conductor osalingana, ndi ma voltage okwera mokwanira ndizofunikira kuti korona ipangidwe. Chifukwa chake, korona idzapangidwa kumapeto kwa mphamvu yamagetsi yapamwamba.motama windings, makamaka pa ma voltage ovoteledwa. Pa ma mota okwera kuposa 6kV, korona wa stator winding idzakhala yoonekera bwino, ndipo voltage ikakwera, vuto la corona lidzakhala lalikulu kwambiri. Chifukwa chake, pa ma windings a ma mota amphamvu kwambiri, njira zothanirana ndi corona zimatengedwa pogwiritsa ntchito mawaya apadera amagetsi ndikuwonjezera matepi oletsa kugwedezeka kunja kwa ma winding coils.

Mota ya ma frequency variable imayendetsedwa ndi chosinthira ma frequency. Mphamvu yamagetsi yotuluka ndi chosinthira ma frequency ndi yosiyana ndi mafunde a sine amagetsi a ma industrial frequency, koma mafunde a sikweya okhala ndi kukwera ndi kugwa kwakukulu. Mafunde apadera a pulse awa amachititsa kuti magetsi olowera a mota azikhala ndi magetsi okhazikika komanso okwera. Mphamvu yowonjezereka yomwe ili kawiri kuposa mphamvu yovotera, chifukwa cha liwiro lachangu kwambiri la mphamvu yowonjezereka ya pulse iyi, imayambitsa kufalikira kwakukulu kwa magetsi m'ma windings a mota. Ngakhale kuti ma mota ambiri a ma frequency variable ndi ma mota otsika mphamvu, njira yapadera yoperekera mphamvu imapangidwira kukhala ndi magetsi osagwirizana m'ma windings awo.

Kuchokera ku kusanthula kwa makhalidwe a kuchuluka kwa ma turns ndi kutalika kwa mota, ma turns oyamba ndi omaliza a low-voltage high-power winding motor amanyamula pafupifupi ma voltage amplitude onse, ndipo ndi omwe amapezeka kwambiri pamavuto a motor winding. Komanso, kuchokera ku kusanthula kwa njira yolumikizira ma curding, Kuwonongeka kwa coil yoyamba yotembenukira kumakhala kwakukulu, motero chiopsezo chimakhala chachikulu. Ichi ndichifukwa chake opanga magalimoto ambiri amapereka chitetezo chapadera pa ma coil oyamba ndi omaliza. Pa ma motors otsika-voltage high-power variable-frequency, chifukwa cha mphamvu yosafanana yamunda ndi voltage ya pulse spike, kumapeto kwa ma curding a mota kuli ndi zinthu zoyambira zopangira corona. Pofuna kupewa kupezeka kwa corona mu mota ya variable frequency, mawaya apadera a anti-corona electromagnetic ayenera kugwiritsidwa ntchito mu ma windings a mota ya variable frequency, ndipo njira zapadera zotetezera ziyenera kutengedwa pa ma coil oyamba ndi omaliza.
