Two basic variants of this winding, the series and parallel ones, are shown. The suppression of higher harmonics is analysed by means of the method of space vectors and symmetrical components. It is shown that the so-called series variant of the combined winding has a better ability to suppress higher spatial harmonics. The paper presents a proposal of an adapted combined winding whose pitch is smaller than that of the used three-phase winding.
