I-Corona ibangelwa insimu kagesi engalingani ekhiqizwa ama-conductor angalingani. Eduze kwensimu kagesi engalingani naseduze kwe-electrode ene-radius encane yokugoba, lapho i-voltage ikhuphuka iye ezingeni elithile, kuzophuma ugesi ngenxa yomoya okhululekile, okwakha i-corona.
Kusukela ezimweni zokukhiqizwa kwe-corona, singathola ukuthi amasimu kagesi angalingani, ama-conductor angalingani, kanye nama-voltage aphezulu ngokwanele kuyizimo ezidingekayo ukuze kukhiqizwe i-corona. Ngakho-ke, i-corona izokhiqizwa ekugcineni kwe-high-voltage.injiniama-windings, ikakhulukazi kuma-voltage alinganisiwe. Kuma-motor aphezulu kune-6kV, i-corona ye-stator winding izoba sobala kakhulu, futhi uma i-voltage iphakeme, inkinga ye-corona izoba nkulu kakhulu. Ngakho-ke, kuma-motor windings aphezulu, kuthathwa izinyathelo zokwelapha i-anti-corona ngokusebenzisa izintambo ezikhethekile ze-electromagnetic kanye nokufaka amatheyipu okumelana ngaphandle kwama-winding coils.
Injini yemvamisa eguquguqukayo inikwa amandla yi-frequency converter. Ukukhishwa kwe-voltage yi-frequency converter kuhlukile ku-sine wave yokunikezwa kwamandla e-industrial frequency, kodwa igagasi eliyisikwele elinokwenyuka nokwehla okukhulu. Leli gagasi elikhethekile le-pulse libangela ukuthi i-input voltage yemoto ibe ne-voltage ephindaphindwayo nephezulu. I-voltage ebukhali ephindwe kabili kune-voltage elinganisiwe, ngenxa yejubane elisheshayo kakhulu lale pulse overvoltage, izobangela ukusatshalaliswa okungalingani okukhulu kwensimu kagesi kuma-windings e-motor. Nakuba iningi lama-variable frequency motors kuyi-low-voltage motors, indlela ekhethekile yokunikezwa kwamandla ihloselwe ukuba nezinkundla zikagesi ezingalingani kuma-windings azo.
Kusukela ekuhlaziyweni kwezici zenani lokujika nobude bemoto, ukujika kokuqala nokokugcina kwemoto enamandla aphezulu aphansi kuthinta cishe wonke amandla kagesi, futhi futhi kuyinkinga enkulu ekujikeni kwemoto. Ngaphezu kwalokho, kusukela ekuhlaziyweni kwenqubo yokushumeka kwemoto, Umonakalo wekhoyili yokuqala yokujika mkhulu kakhulu, ngakho-ke ingozi inkulu. Yingakho abakhiqizi abaningi bemoto behlinzeka ngokuvikelwa okukhethekile kwamakhoyili okuqala nawokugcina. Kumamori anamandla aphezulu aphansi anamandla aphezulu aguquguqukayo, ngenxa yamandla ensimu angalingani kanye ne-pulse spike voltage, ukuphela kokujikisa kwemoto kunezimo eziyisisekelo zokukhiqizwa kwe-corona. Ukuze kuvinjelwe ukwenzeka kwe-corona kumoto eguquguqukayo eguquguqukayo, izintambo ezikhethekile ze-anti-corona electromagnetic kufanele zisetshenziswe ekujikeni kwemoto eguquguqukayo eguquguqukayo, futhi kufanele kuthathwe izinyathelo ezikhethekile zokuvikela kumakhoyili okuqala nawokugcina.
