  • J. Buksnaitis Kauno technologijos universitetas


There is carried out the research of three phased fractional slot windings magnetic forces, while using these windings magnetic force waves, which are changing in the time and space, graphical pattern, which are obtained on the basis of this windings electric circuit and phases current vectors diagrams. It is selected in the moment of time for the obtained magnetic force spatial function like for the periodical step function is carried out harmonic analysis. The newly maid expressions on the principle of superposition basis were used for this analysis. The relative quantities were calculated lower and higher rows spatial harmonics with respect to fundamental out of obtained results. In the work it is carried out the electromagnetic estimation of three phased fractional slot windings.
