Ruzha rwemagetsi emagetsi runogona kukamurwa kuita mapoka matatu: aerodynamic, mechanical uye electromagnetic ruzha masosi. Mumakore achangopfuura, vanhu vakabhadhara zvakanyanya uye zvakanyanya kutarisisa kukanganiswa kwemagetsi emagetsi ruzha. Izvi zvinonyanya kukonzerwa nezvikonzero zviviri: (a) kune madiki uye epakati-saizi mota, kunyanya mota dzakayerwa pazasi 1.5kW, ruzha rwemagetsi runotonga munda weacoustic; (b) rudzi urwu rweruzha runonyanya kukonzerwa nekuoma kwekuchinja magineti emota kana yangogadzirwa.
Muzvidzidzo zvakapfuura, kukanganisa kwezvinhu zvakasiyana-siyana paruzha rwemotokari kwakaongororwa zvakanyanya, senge mhedzisiro yepulse wide modulation ikozvino pane acoustic ruzha maitiro emukati asingagumi magineti synchronous mota madhiraivha; mhedzisiro ye windings, mafuremu uye impregnation pane stator resonant frequency; mhedzisiro ye core clamping pressure, windings, wedges, mazino chimiro, tembiricha, etc. pane vibration maitiro e stator yemhando dzakasiyana dzemotor.
Nekudaro, maererano ne stator core laminations, maitiro eiyo vibration maitiro emota haasati anyatso dzidza, kunyangwe zvichizivikanwa kuti clamping ye laminations inogona kuwedzera kuoma kwepakati uye kunyangwe mune dzimwe nguva vanogona kuita senge. chinhu chekuvhunduka. Zvidzidzo zvizhinji zvinoenzanisira iyo stator musimboti sehukobvu uye yunifomu cylindrical musimboti kudzikisa kuomarara kwemuenzaniso uye mutoro wekombuta.
Muongorori weYunivhesiti yeMcGill Issah Ibrahim nechikwata chake vakadzidza mabatiro emaminetsi uye asina-laminated stator cores paruzha rwemota nekuongorora nhamba huru yemasampuli emota. Vakavaka modhi dzeCAD zvichienderana neyakayerwa geometric dimensions uye zvimiro zveiyo mota chaiyo, ine referensi modhi iri 4-pole, 12-slot yemukati inogara magineti synchronous mota (IPMSM). Kuenzanisira kweiyo laminated stator core yakapedzwa uchishandisa Laminated Model Toolbox muSimcenter 3D, iyo yakaiswa maererano neyakagadzirwa nemugadziri, kusanganisira parameters senge damping coefficient, lamination nzira, interlayer allowance, uye shear uye zvakajairika kushushikana kweadhesive. Kuti vanyatso ongorora ruzha rweacoustic rwakaburitswa nemota, vakagadzira inoshanda acoustic modhi inobvumira kubatanidza pakati pe stator uye fluid, kuenzanisira acoustic fluid yakatenderedza iripo stator chimiro chekuongorora iyo acoustic ndima yakatenderedza IPM mota.
Vatsvakurudzi vakacherechedza kuti maitiro ekudengenyeka kweiyo laminated stator core ane yakaderera resonant frequencies maererano ne-non-laminated stator core yeimwe injini geometry; zvisinei nekudzokororwa kazhinji panguva yekushanda, iyo inzwi rekumanikidza kweiyo laminated stator core mota dhizaini yaive yakaderera pane yaitarisirwa; iyo correlation coefficient value inodarika 0.9 inoratidza kuti computational cost ye modelling laminated stators for acoustic studies inogona kuderedzwa nekuvimba ne surrogate model kuti inyatso fungira kuti sound pressure level yeyakaenzana solid solid stator core.
