Porównanie parametrów silnika dwufazowego i trójfazowego zasilanych z przekształtników

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.
