Ukuze kuphuculwe umgangatho wemoto, kwiminyaka yakutshanje, ingxolo yemoto iye yafakwa kwenye yezalathisi zovavanyo lomgangatho, ngakumbi kwindawo yokusebenza yemoto kunye nokunxibelelana kwabantu kufutshane nemeko, ingxolo yemoto iye yaba yinto ehambelanayo. iimfuno zovavanyo ezibaluleke kakhulu.
Ukuze ulawule ii-asynchronous motoringxolo, ukongeza kuyilo lwe-stator kunye ne-rotor slot kunye nokukhethwa okufanelekileyo kwe-stator kunye ne-rotor slot ngaphandle kwe-slot slot ingasetyenziselwa ukunciphisa ingxolo ye-electromagnetic ye-motor. Kodwa kanye ukuba singakanani i-slope esifanelekileyo esifanelekileyo, uvavanyo olongezelelweyo luyafuneka ukuze kuqinisekiswe.
Ngokubanzi, i-rotor slot ye-slope yee-asynchronous motors inokuthathwa njenge-stator yezinyo pitch enye, enokuthi ihlangabezane neemfuno. Nangona kunjalo, ukuze kuphuculwe ngakumbi ingxolo yeemoto, kuyimfuneko ukuphonononga i-slope ye-slope efanelekileyo, efuna inani elikhulu lokubala kunye nokuqinisekisa.
Ihlalutywe ukusuka kwindawo yokwenziwa kwemboniselo, imveliso ye-motor slot ethe tye kunye nokucubungula ukuba kube lula, kodwa xa kuyimfuneko, kuya kufuneka ukuba ibe yi-stator slot okanye i-rotor slot torsion. I-slot slot torsion inzima, kwaye ke, kwiimeko ezininzi, i-rotor slot tilting. I-Rotor slot torsion ngokubanzi ngokusebenzisa i-shaft processing torsion yendlela engundoqo yokufezekisa, amashishini ezixhobo eziqhubela phambili, ukusetyenziswa kwe-spiral punching, kwinkqubo yokwenziwa kwe-rotor core ukufikelela.
Ingxolo ye-electromagnetic ibangela kunye nemilinganiselo yokuphepha
Ingxolo yeemoto ibisoloko iyingxaki enzima ukuyicombulula, iveliswa ikakhulu ngumbane, oomatshini, ukuphefumla ngezizathu ezithathu. Ingxolo ye-electromagnetic kwi-asynchronous motor kungenxa yestator kunye ne-rotor currents kwi-gap yomoya esekwe kwi-harmonic field magnetic interaction kunye ne-electromagnetic force wave ebangelwa yi-core vibration yedyokhwe, ukunyanzela okujikelezayo.ukungcangcazela komoyakwaye iveliswe. Esona sizathu siphambili kungenxa ye-slot engafanelekanga, i-stator kunye ne-rotor eccentricity okanye i-gap encinci yomoya.
Ingxolo ye-electromagnetic ibangelwa kukuxinana kwemagnethi okwenza utshintsho kwixesha nakwindawo kwaye kusetyenzwa ngamalungu ahlukeneyo enjini. Ke ngoko, kwiinjini ze-asynchronous, oonobangela bokwenziwa kwengxolo ye-electromagnetic ziquka:
● Amaza okukhanya okukhanya kwisithuba somoya umhlaba wemagnethi abangela ukuguqulwa kweradial kunye nokungcangcazela ngamaxesha athile kwistator kunye nerotor.
● Amaza okukhanya emitha yee-harmonics eziphezulu kwi-gap yomoya yomhlaba wemagnethi asebenza kwi-stator kunye ne-rotor cores, ebangela ukuba bangene kwi-deformation ye-radial kunye nokungcangcazela ngamaxesha.
● Ukuguqulwa kweendlela ezahlukeneyo ze-harmonics ze-stator core zineendlela ezahlukeneyo ze-intrinsic, kwaye i-resonance ibangelwa xa i-frequency ye-radial force wave isondele okanye ilingana neyodwa ye-intrinsic frequencies ye-core.
I-stator deformation ibangela ukuba umoya ojikelezileyo ungcangcazele, kwaye uninzi lwengxolo ye-electromagnetic yingxolo yomthwalo.
Xa i-core igcwele, inxalenye yesithathu ye-harmonic iyanda, kwaye ingxolo ye-electromagnetic iyanda.
I-stator kunye ne-rotor slots zivuliwe zonke, kwaye kukho "amaza okuvula i-slot" amaninzi aveliswa phantsi kwentshukumo ye-waves engundoqo enokubakho kwi-air gap magnetic field, kwaye incinci i-gap yomoya, i-slots ebanzi, i-amplitude enkulu.
Ukuze ugweme ingxaki, i-ofisi kwinqanaba loyilo lwemveliso ngeendlela ezithile ezisebenzayo zokuphucula, ezifana: ukukhetha ubuninzi be-magnetic flux, ukukhetha uhlobo olufanelekileyo lokujikeleza kunye nenani leendlela ezinxulumene nazo, ukwandisa inani le-stator. ukubhobhoza kwiindawo zokubeka, ukunciphisa i-harmonic yokusabalalisa i-coefficient ye-stator windings, ukulungiswa okufanelekileyo kwe-stator-rotor air gap motor, ukukhetha i-stator kunye ne-rotor groove kunye ne-rotor slant groove, ukusetyenziswa kwe-rotor, kunye namanye amanyathelo athile.
