Abstract:
This work is devoted to preliminary investigations concerning the effect of an inertia moment and load-speed characteristics on currents, power losses and windings temperature of an induction machine supplied with voltage containing subharmonics. The results of numerical simulations are presented for a totally-enclosed fan-cooled cage induction motor of rated power 3 kW. The computations were carried out with a field method and a hybrid field-circuit method. The results of preliminary investigations show that load properties may have significant influence on currents, power losses and windings temperature of an induction machine under considered power quality disturbances.
Streszczenie:
Artykuł jest poświęcony wstępnym badaniom wpływu momentu bezwładności i charakterystyki obciążenia na prądy, straty mocy oraz temperaturę uzwojeń silnika indukcyjnego, zasilanego napięciem zawierającym subharmoniczne. Wyniki obliczeń numerycznych przedstawiono dla silnika indukcyjnego klatkowego budowy całkowicie zamkniętej o mocy 3 kW. Obliczenia wykonano za pomocą metody polowej oraz polowo-obwodowej. Prezentowane wyniki badań dowodzą, że właściwości obciążenia mogą mieć istotny wpływ na prądy, straty mocy oraz temperaturę uzwojeń silnika indukcyjnego w warunkach rozważanych zaburzeń.
