Zaznavanje napačnega kota pri komutaciji sinhronega motorja s trajnimi magneti : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoBačar, UrbanZaradi svojih dobrih lastnosti, kot so visoka efektivnost, moč in gostota moči se sinhroni motorji zelo uporabljajo v industrijskem okolju. V zadnjem času, ko se avtomobilski pogoni vse bolj ... premikajo od klasičnih motorjev z notranjim izgorevanjem k električnim ali vsaj hibridnim pogonskim sklopom, pa imajo vse večji pomen v avtomobilski industriji. Uporabljajo se kot pogonski element v obliki centralnega motorja, in sicer v blizu-kolesni ali v-kolesni obliki. Zadnja je večji razvoj in pozornost začela doživljati v zadnjih nekaj letih. Pri tem je dobro izvedeno in zanesljivo krmiljenje pomemben faktor, saj zelo vpliva na višji izkoristek sistema, zmanjšanje hrupnosti in vibracij ter večjo varnosti potnikov. V diplomski nalogi je potrebno raziskati, kako bi lahko s pomočjo napetosti Ud, ki jo dobimo pri krmiljenju motorja na osnovi polja, zaznali, ali je prišlo do napačne zaznave kota med statorjem in rotorjem elektromotorja. Le ta je namreč bistvenega pomena za pravilno komutacijo. Na merilnem mestu smo zajeli meritve in iz njih interpolirali površine, ki predstavljajo odvisnost napetosti Ud od hitrosti motorja in navora v celotnem delovnem območju motorja, pri različnih kotnih nastavitvah. Te smo na koncu primerjali še z meritvami na avtomobilu in določli ali je metoda primerna za nadaljno uporabo.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [U.
