The aim of the use of the combined winding is to suppress a chosen group of higher spatial harmonics of the current layer and magnetic flux density in the air gap and the magnetic flux in the yoke. The suppression of the higher spatial harmonics results in decreasing the losses and improving the energy efficiency of the machine. The differential equations are stated for both the considered variants. On the basis of the numerical solution of these equations, the ability of individual variants to suppress higher harmonics has been shown. The validity of the equations has been verified by experimental measurements on a physical model of an induction machine with the combined star-delta stator winding.
