VPLIV KONSTRUKCIJE ROTORJA NA SAMODRŽNI VRTILNI MOMENT GENERATORJA S POVRŠINSKO NAMEŠČENIMI TRAJNIMI MAGNETI
Povzetek
Članek obravnava analizo samodržnega vrtilnega momenta generatorja s površinsko nameščenimi trajnimi magneti z namenom določitve konstrukcijskih izboljšav oz. metod za zmanjšanje tovrstnega vrtilnega momenta. Obravnavan je štiri polni generator s površinsko nameščenimi trajnimi magneti pri čemer je analiza izvedena z uporabo metode končnih elementov (MKE). V prispevku so analizirane možnosti za zmanjšanje samodržnega vrtilnega momenta z uvedbo asimetrije na rotorju. Analizirana sta dva tipa asimetrije: spremenjena dolžina obodnega loka trajnih magnetov in zamik trajnih magnetov. Pridobljeni numerični rezultati za asimetrične primere so primerjani z simetričnimi. V zaključku sledi razprava v zvezi s pridobljenimi rezultati numeričnih simulacij.
