Ukufunda ngokulahlekelwa okuyisisekelo kwe-silicon steel motor stator uma kucatshangelwa izinga lokushisa kanye nengcindezi ecindezelayo

Njengoba i-motor core ivame ukuthinteka yizinto ezihlukahlukene ezibonakalayo ezifana nenkundla kazibuthe, indawo yokushisa, inkambu yokucindezeleka, kanye nemvamisa phakathi nenqubo yokusebenza; ngasikhathi sinye, izici ezihlukene zokucubungula ezifana nengcindezi eyinsalela ekhiqizwe ukugxivizwa nokucheba amashidi ensimbi ye-silicon, ibanga phakathi kwegobolondo ne-stator core Ukucindezeleka okucindezelwayo okukhiqizwa umkhono wokushisa, ukungezwani kwe-centrifugal okukhiqizwa ukusebenza kwesivinini esikhulu. we-rotor, kanye nezinga lokushisa le-gradient elikhiqizwe izici zokukhuphuka kwezinga lokushisa kuzothinta ukusebenza okuphelele kwengqikithi. Lezi zici zizobangela ukulahlekelwa kwensimbi ye-motor core ibe phezulu kunevelu evamile futhi kubangele ukuwohloka okungenakunakwa.

Imiphumela yocwaningo ekhaya nakwamanye amazwe ikhombisa ukuthi: umgogodla wensimbi wenjini uvamise ukusebenza ekushiseni okuphezulu, ukulahleka kwensimbi kweshidi lensimbi elijwayelekile le-silicon kuncipha ngokunyuka kwezinga lokushisa, kanti ukulahleka kwensimbi okungu-6.5% okuphezulu kwe-silicon kukhuphuka ukwanda kwezinga lokushisa. Kumamotho afakwe ngokulingana kokuphazamiseka ecaleni, icala lizofaka ingcindezi enkulu kumongo wensimbi, kanti umgogodla wensimbi uzothwala ukucindezeleka okucindezelwayo okungaba ngu-10Mpa-150Mpa ngesikhathi sokusebenza, kanti uhlobo lwe-iron core lusiza kakhulu ukukhiqizwa ngobuningi, okuvamise ukuba Inqubo yokuncipha noma yokuminyanisa iyadingeka ukuze kulungiswe umongo, futhi ukulahlekelwa kwensimbi nge-shrink fit noma ukulingana kokucindezela kukhuphuka kakhulu uma kuqhathaniswa nekesi elingacindezelwe. Okuqukethwe kwe-silicon okungu-6.5% okuphezulu kwe-silicon steel kuphakeme kakhulu kunokwensimbi ye-silicon yendabuko, ngakho-ke ukulahlekelwa kwensimbi kwe-6.5% high silicon steel kuphansi ngenxa yokwanda kwengcindezi yokucindezela, kuyilapho ukulahlekelwa kwensimbi yensimbi ye-silicon yendabuko kuphezulu ngenxa ekwandeni kokucindezeleka okucindezelayo. Ukuwohloka kokulahlekelwa kwensimbi ngokucindezeleka okucindezelayo kulinganiselwe, futhi lapho ukucindezeleka kufinyelela inani elithile, ukuwohloka kokulahlekelwa kwensimbi akusabonakali.

U-Ma Deji, umcwaningi e-Shenyang University of Technology, uhlole izakhiwo kazibuthe zensimbi engu-6.5% ephezulu ye-silicon ngaphansi kwezimo zokucindezelwa okucindezelwayo nokuhlangana kwezinga lokushisa, futhi wabuyekeza imodeli yokulahlekelwa kwensimbi, futhi waqhathanisa u-6.5 % wensimbi ephezulu ye-silicon ne-silicon yendabuko. insimbi. Ngokombono wezinto zokwakha, izinzuzo ze-6.5% high silicon steel ziyahlaziywa. Futhi buyisela kumongo wemoto ukuze wenze ukusebenza kwawo kube kuhle kakhulu.

Ngocwaningo mayelana nokusebenza kokulahlekelwa kwensimbi okungu-6.5% Si ngaphansi kwezinga lokushisa eliguquguqukayo nokucindezeleka, abacwaningi bathola ukuthi: lapho izinga lokushisa kanye nokucindezeleka okucindezelwayo okusebenza kulokho kukhula, uma kuqhathaniswa nezinye izinsimbi ze-silicon zendabuko, ukuwohloka kokulahlekelwa kwe-6.5 % Si. kuncane kakhulu; I-6.5% yensimbi ephezulu ye-silicon inokuwohloka okuncane kokulahlekelwa kwensimbi ngaphansi kwezimo zokuhlanganisa eziningi ze-physics ngenxa yokucindezeleka kwangaphakathi, i-hysteresis coefficient encane kanye nosayizi omkhulu wokusanhlamvu; lapho insimbi engu-6.5% ephezulu ye-silicon isetshenziselwa ukwenza i-motor stator core, i-casing ithatha i-shrink fit Ifakwe ngendlela efanayo, kuzoba nokulahlekelwa okuncane kwensimbi.
