Phokoso la ma motors amagetsi likhoza kugawidwa m'magulu atatu: magwero a aerodynamic, mechanical ndi electromagnetic phokoso. M'zaka zaposachedwa, anthu akhala akuyang'anitsitsa kwambiri mphamvu ya magwero a phokoso la electromagnetic. Izi makamaka chifukwa cha zifukwa ziwiri: (a) kwa Motors ang'onoang'ono ndi sing'anga-kakulidwe, makamaka Motors oveteredwa pansipa 1.5kW, electromagnetic phokoso limalamulira munda wamayimbidwe; (b) Phokoso lamtundu uwu makamaka chifukwa chazovuta kusintha mphamvu ya maginito ya injini ikangopangidwa.
M'maphunziro am'mbuyomu, zotsatira za zinthu zosiyanasiyana paphokoso lagalimoto zakhala zikufufuzidwa mofala, monga momwe kusinthira kwamphamvu kwamphamvu pamayendedwe a phokoso lamayendedwe amkati okhazikika a maginito synchronous motor; zotsatira za windings, mafelemu ndi impregnation pa stator resonant pafupipafupi; zotsatira za pachimake clamping kuthamanga, windings, wedges, dzino mawonekedwe, kutentha, etc. pa kugwedera khalidwe la stator a mitundu yosiyanasiyana ya Motors.
Komabe, ponena za stator core laminations, zotsatira za khalidwe la kugwedezeka kwa galimoto sizinaphunzire mokwanira, ngakhale zimadziwika kuti kugwedeza kwa laminations kumatha kuonjezera kuuma kwa pachimake ndipo ngakhale nthawi zina amatha kuchita ngati. chomangira mantha. Maphunziro ambiri amatengera ma stator core ngati cylindrical core yokhuthala komanso yofananira kuti achepetse zovuta zamafanizo komanso kulemedwa.
Wofufuza pa yunivesite ya McGill, Issah Ibrahim ndi gulu lake adaphunzira momwe ma stator cores okhala ndi laminated komanso opanda laminated pa phokoso la galimoto pofufuza zitsanzo zambiri zamagalimoto. Anapanga zitsanzo za CAD kutengera miyeso ya geometric ndi zinthu zakuthupi za injiniyo, ndi chitsanzo chokhala ndi 4-pole, 12-slot inside permanent magnet synchronous motor (IPMSM). The chitsanzo cha laminated stator pachimake anamaliza ntchito Laminated Model Toolbox mu Simcenter 3D, amene anaikidwa malinga ndi specifications wopanga, kuphatikizapo magawo monga damping coefficient, njira lamination, interlayer allowance, ndi kukameta ubweya ndi kupsyinjika wabwinobwino wa zomatira. Pofuna kuwunika molondola phokoso lamayimbidwe opangidwa ndi galimotoyo, adapanga njira yabwino yolumikizirana yomwe imalola kulumikizana pakati pa stator ndi madzimadzi, kutengera mawonekedwe amadzimadzi ozungulira mawonekedwe a stator omwe alipo kuti athe kusanthula gawo lamayimbidwe mozungulira injini ya IPM.
Ofufuzawo adawona kuti mitundu yogwedezeka ya pakatikati ya stator ya laminated imakhala ndi ma frequency otsika ocheperako poyerekeza ndi pakatikati pa stator yopanda laminated ya geometry yamoto yomweyo; ngakhale ma resonances pafupipafupi pakugwira ntchito, kuthamanga kwamphamvu kwa kapangidwe ka mota ka laminated stator kunali kocheperako kuposa momwe amayembekezera; mtengo wamalumikizidwe wopitilira 0.9 ukuwonetsa kuti mtengo wowerengera wa ma stator a laminated pamaphunziro amawu ukhoza kuchepetsedwa podalira mtundu wina kuti uyerekeze molondola kuchuluka kwa mawu amtundu wofanana wa stator core.
