Umsindo wamamotho kagesi ungahlukaniswa izigaba ezintathu: imithombo yomsindo we-aerodynamic, mechanical kanye ne-electromagnetic. Eminyakeni yamuva nje, abantu baye banaka kakhulu umthelela wemithombo yomsindo we-electromagnetic. Lokhu ikakhulukazi kungenxa yezizathu ezimbili: (a) kumamotho amancane naphakathi nendawo, ikakhulukazi amamotho alinganiselwe ngaphansi kuka-1.5kW, umsindo kazibuthe ubusa inkambu ye-acoustic; (b) lolu hlobo lomsindo ngokuyinhloko lubangelwa ubunzima bokushintsha izici kazibuthe zenjini uma seyenziwa.
Ezifundweni zangaphambilini, umthelela wezici ezihlukahlukene kumsindo wezimoto uye wahlolwa kabanzi, njengomphumela wokuguquguquka kobubanzi be-pulse wamanje ekuziphatheni komsindo we-acoustic wamadrayivu e-motor synchronous motor yangaphakathi unomphela ozibuthe; umthelela wama-windings, amafreyimu kanye nokufakwa ku-stator resonant frequency; umthelela wokucindezelwa kwe-core clamping, ama-winding, ama-wedji, ukuma kwamazinyo, izinga lokushisa, njll. ekudlidlizeni kokuziphatha kwe-stator yezinhlobo ezahlukene zamamotho.
Kodwa-ke, ngokuya nge-stator core laminations, umthelela ekuziphatheni kokudlidliza kwemoto awukafundwa ngokugcwele, nakuba kwaziwa ukuthi ukugoqa ama-laminations kungandisa ukuqina komgogodla futhi kwezinye izimo bangase basebenze njenge-clamping. i-shock absorber. Ucwaningo oluningi lumodela umgogodla we-stator njengomgogodla owugqinsi futhi ofanayo ukuze kuncishiswe ubunkimbinkimbi bokumodela kanye nomthwalo wokubala.
Umcwaningi waseNyuvesi yaseMcGill u-Issah Ibrahim kanye nethimba lakhe bafunde umthelela wama-stator cores alaminethiweyo nangenawo laminate emsindweni wemoto ngokuhlaziya inani elikhulu lamasampula emoto. Bakhe amamodeli e-CAD asuselwa kubukhulu bejometri obukaliwe kanye nezakhiwo zezinto ezibonakalayo zenjini yangempela, imodeli eyireferensi eyi-4-pole, 12-slot inside permanent magnet synchronous motor (IPMSM). Ukumodela kwe-laminated stator core kwaqedwa kusetshenziswa I-Laminated Model Toolbox ku-Simcenter 3D, eyasethwa ngokuvumelana nezicaciso zomkhiqizi, okuhlanganisa nemingcele efana ne-damping coefficient, indlela yokugcoba, i-interlayer allowance, nokugunda nokucindezeleka okuvamile kokunamathelayo. Ukuze kuhlolwe kahle umsindo we-acoustic okhishwa injini, bathuthukise imodeli ye-acoustic esebenza kahle evumela ukuhlangana phakathi kwe-stator noketshezi, imodela uketshezi lwe-acoustic eduze kwesakhiwo esikhona se-stator ukuhlaziya inkambu ye-acoustic ezungeze injini ye-IPM.
Abacwaningi baqaphele ukuthi izindlela zokudlidliza ze-laminated stator core zinemvamisa ephansi ye-resonant ehlobene ne-non-laminated stator core ye-motor geometry efanayo; naphezu kwama-resonances avamile phakathi nokusebenza, izinga lokucindezela komsindo we-laminated stator core motor design laliphansi kunalokho obekulindelwe; inani le-coefficient yokuhlobanisa elingaphezu kuka-0.9 libonisa ukuthi izindleko zokubala zokumodela izilinganiselo ze-laminated zezifundo ze-acoustic zingancishiswa ngokuthembela kumodeli yokuthatha indawo yokuhlala ukuze ilinganisele ngokunembile izinga lokucindezela komsindo we-stator core eqinile efanayo.
