Ingxolo yeenjini zombane inokwahlulwa ibe ngamacandelo amathathu: imithombo yengxolo ye-aerodynamic, oomatshini kunye ne-electromagnetic. Kwiminyaka yakutshanje, abantu baye banikela ingqalelo ngakumbi nangakumbi kwimpembelelo yemithombo yengxolo ye-electromagnetic. Oku kungenxa yezizathu ezibini: (a) kwiinjini ezincinci kunye neziphakathi, ngakumbi iimotor ezibekwe ngaphantsi kwe-1.5kW, ingxolo ye-electromagnetic ilawula intsimi ye-acoustic; (b) olu hlobo lwengxolo lubangelwa ikakhulu kubunzima bokutshintsha iimpawu zemagnethi zemoto xa sele yenziwe.
Kwizifundo zangaphambili, impembelelo yezinto ezahlukeneyo kwingxolo yemoto iye yaphononongwa ngokubanzi, njengesiphumo sokumodareyitha kobubanzi be-pulse ngoku kwindlela yokuziphatha yengxolo ye-acoustic yangaphakathi yemagnethi esisigxina ye-synchronous motor drives; impembelelo yee-windings, iifreyimu kunye nokufakelwa kwi-stator resonant frequency; impembelelo yoxinzelelo lwe-core clamping, i-windings, i-wedges, imilo yezinyo, ubushushu, njl.njl kwi-vibration yokuziphatha kwe-stator yeentlobo ezahlukeneyo zeenjini.
Nangona kunjalo, ngokwemiqathango ye-stator core laminations, impembelelo kwindlela yokuziphatha kwe-vibration ye-motor ayizange ifundwe ngokupheleleyo, nangona iyaziwa ukuba i-clamping ye-laminations inokunyusa ukuqina kombindi kwaye nakwezinye iimeko zinokwenza njenge. into yokutsala ukothuka. Uninzi lwezifundo zenza imodeli ye-stator core njengombindi otyebileyo kunye nofanayo wecylindrical ukunciphisa ubunzima bemodeli kunye nomthwalo wokubala.
Umphandi weYunivesithi yaseMcGill u-Issah Ibrahim kunye neqela lakhe bafunde impembelelo ye-stator cores laminated kunye ne-non-laminated kwi-motor ingxolo ngokuhlalutya inani elikhulu leesampuli zeemoto. Bakhe iimodeli ze-CAD esekwe kumlinganiselo olinganisiweyo wejometri kunye neepropathi zezinto eziphathekayo zemoto yokwenyani, kunye nemodeli yesalathiso ibe yi-4-pali, i-12-slot yangaphakathi yemagnethi esisigxina ye-synchronous motor (IPMSM). Ukwenziwa kondoqo we-stator elaminethiweyo kwagqitywa kusetyenziswa i-Laminated Model Toolbox kwi-Simcenter 3D, eyamiselwa ngokweenkcukacha zomenzi, kubandakanywa iiparamitha ezifana ne-coefficient ye-damping, indlela yokulahla, isibonelelo se-interlayer, kunye nokucheba kunye noxinzelelo oluqhelekileyo lwe-adhesive. Ukuze uvavanye ngokuchanekileyo ingxolo ye-acoustic ekhutshwe yi-motor, baphuhlise imodeli esebenzayo ye-acoustic evumela ukudibanisa phakathi kwe-stator kunye nolwelo, imodeli ye-acoustic fluid malunga nesakhiwo esikhoyo se-stator ukuhlalutya intsimi ye-acoustic malunga ne-IPM motor.
Abaphandi baqaphela ukuba iindlela zokungcangcazela kwe-stator core ye-laminated ine-resonant frequencies ephantsi ngokumalunga ne-non-laminated stator core ye-motor geometry efanayo; nangona i-resonances rhoqo ngexesha lokusebenza, inqanaba loxinzelelo lwesandi kwi-laminated stator core motor design yayingaphantsi kunokulindelekile; ixabiso le-coefficient yolungelelaniso elidlula i-0.9 libonisa ukuba iindleko zokubala zokulinganisa i-stator laminated kwizifundo ze-acoustic zingancitshiswa ngokuthembela kwimodeli ye-surrogate ukuqikelela ngokuchanekileyo inqanaba loxinzelelo lwesandi se-stator eqinile elinganayo.
