Vpliv modulacijske frekvence na izgube elektromotornega pogona, harmonsko popačenje toka in temperaturo asinhronskega motorja = The impact of modulation frequency on losses, current harmonic distortion and motor temperature in an induction motor driveMarčič, Tine ...Delovanje elektromotornega pogona spremenljive hitrosti spremljajo izgube v pretvorniku in motorju, ki so odvisne od modulacijske frekvence. V delu je predstavljena analiza vpliva modulacijske ... frekvence na izgube celotnega pogona, pretvornika in površinsko hlajenega trifaznega asinhronskega motorja zaprte izvedbe s kratkostično kletko. Vpliv modulacijske frekvence je ovrednoten na podlagi primerjave rezultatov meritev segrevanja nazivno obremenjenega asinhronskega motorja, ki je napajan s pretvornikom. Pri tem so referenčne vrednosti amplitude in frekvence izhodnih napetosti pretvornika ves čas konstantne, modulacijska frekvenca pa se spreminja. V delu predstavljeni izsledki kažejo, da se izgube pretvornika večajo, izgube motorja pa manjšajo z večanjem modulacijske frekvence. Za testni pogon je določena modulacijska frekvenca, pri kateri so izgube celotnega pogona najmanjše. Podani rezultati kažejo, da je harmonsko popačenje toka motorja neposredno povezano s povečanjem izgub in temperaturo motorja.Source: Elektrotehniški vestnik. - ISSN 0013-5852 (Vol. 73, no. 2-3, 2006, str. 125-130)Type of material - article, component part ; adult, seriousPublish date - 2006Language - slovenianCOBISS.SI-ID - 10672150
