Corona inokonzerwa nemagetsi asina kuenzana anogadzirwa nemaconductor asina kuenzana. Akakomberedza magetsi asina kuenzana uye pedyo neelectrode ine radius diki yekukombama, kana voltage yakwira kusvika padanho rakati, kubuda kwemhepo yakasununguka kunoitika nekuda kwemhepo yakasununguka, zvichigadzira korona.
Kubva mumamiriro ezvinhu ekugadzira korona, tinogona kuona kuti minda yemagetsi isina kuenzana, maconductor asina kuenzana, uye voltage yakakwira zvakakwana zvinhu zvinodiwa pakugadzira korona. Nokudaro, korona ichagadzirwa pamagumo emagetsi ane simba guru.motamawindings, kunyanya pamavoltage akayerwa. Kune mota dzakakwira kupfuura 6kV, corona ye stator winding ichave pachena, uye kana voltage yakakwira, dambudziko re corona richava rakakura. Saka, kune mawindings emota ane voltage yakakwira, matanho ekurapa ekudzivirira corona anotorwa nekushandisa waya dzemagetsi dzakagadzirwa uye kuwedzera matepi ekudzivirira kunze kwema winding coils.
Mota yevariable frequency inofambiswa ne frequency converter. Voltage output ne frequency converter yakasiyana ne sine wave ye industrial frequency power supply, asi square wave ine steep rising and fall. Iyi special pulse wave inoita kuti input voltage yemota ive ne periodically uye high voltage. Sharp overvoltage inopetwa kaviri pane rated voltage, nekuda kwekumhanya kukuru kwe pulse overvoltage iyi, inokonzera kusagovaniswa kwakanyanya kwe electric field muma motor windings. Kunyangwe akawanda ma variable frequency motors ari low-voltage motors, special power supply method yakagadzirirwa kuva ne electric fields dzisina kufanana muma windings adzo.
Kubva pakuongorora hunhu hwehuwandu hwekutenderera uye kureba kwemota, kutenderera kwekutanga nekwekupedzisira kwemota ine simba rakaderera remagetsi anosvika pahuwandu hwemagetsi akawandisa, uye zvakare ndiwo anonyanya kukonzera matambudziko mukutenderera kwemota. Uyezve, kubva pakuongorora maitiro ekubatanidza mawinding, Kukuvadzwa kwekoiri yekutanga yekutendeuka kwakakura, uye nekudaro njodzi yakakura. Ndokusaka vagadziri vazhinji vemota vachipa dziviriro yakakosha kumakoiri ekutanga neekupedzisira. Kune mota dzine simba rakaderera remagetsi akawandisa, nekuda kwesimba remunda risina kuenzana uye voltage yekuputika kwepulse, kuguma kwemota kune mamiriro ekutanga ekugadzira korona. Kuti kudzivirira kuitika kwekorona mumota ine simba rakawanda, waya dzemagetsi dzinorwisa corona dzinofanira kushandiswa mumawinding emota ine simba rakawanda, uye matanho ekudzivirira akakosha anofanira kutorwa kumakoiri ekutanga neekupedzisira.
