The Magnetic Field of Three Phased Chain Windings

Abstract

There was carried out the research of the three phased chain windings magnetic field. There were showed that the spatial functions of these windings magnetic forces in some time moments are symmetrical with respect to the coordination axis start point and in some - they are asymmetrical. This means, that the functions of such type have not only odd harmonics, but also the even spatial harmonics unreprated for three. There were made the analytical expressions for the spreading into Fourier series of step form magnetic forces curves, which are symmetrical with respect to the coordination axis start point. On this basis there was carried out harmonical analysis of searching windings magnetic forces. There were compared magnetic fields of chain windings and equivalent to them concentrated windings.
