W artykule przedstawiono źródło i porównano skutki zniekształceń w generowanych napięciach fazowych trójgałęziowego falownika napięcia na przebiegi napięć i prądów w zasilanym silniku indukcyjnym dwu- i trójfazowym, wywołanych występowaniem czasów martwych. Zaprezentowano również metodę kompensacji czasów martwych opartą na śledzeniu kierunku prądów wyjściowych falownika.

The article presents the source and compares results of phase voltage distortions generated in three-leg voltage source inverter on voltage and current waveforms in two- and three-phase induction motor caused by the presence of dead-time. Presented dead-time compensation method is based on tracking direction of the inverter output currents.

The article presents researches results of one-phase drivers equipped with two- and three-phase induction cage motors with solid rotor core. The motors have been constructed on the base of typical three-phase induction cage motor with two-poles and shaft height 90 mm. Typical sliced core was removed from shaft and replaced with solid core. The solid rotor was tested in two- and three-phase stators of experimental motors powered from electronic inverter. There are presented comparative researches results of drivers at continuous work with decreased load due to highest temperature growth and torques characteristics at different frequency. All comparisons were preformed for several air gap value.

In this article has been presented researches results of drivers constructed on the base of typical three-phase induction cage motor with rated power 1500 W, shaft height 90 mm and one pole pair. There has been described changes concerning the types and parameters of windings used in experimental two-phase and three-phase motors. There has been presented parameters and characteristics of motors which are in cooperation with energoelectronic inverters powered from one-phase power grid 230 V and smoothly tuned the rotation speed. Additionally to comparison of motors parameters there has been presented also researches results of this machines powered from three-phase power grid 3×400 V appropriately. There has been comprised manners of motors powered from power grid and from inverters. Moreover, there has been performed costs analysis of motors and inverters produces. There have been performed also comparison analyses of two-phase and three-phase motors powered from power grid and from inverters. The comparison concerned the parameters of one motor powered from different power sources as well as parameters different motors powered from the same power source.
