Such a winding can be used in two-speed induction motors for turbo mechanisms. The scheme of the new winding was obtained by using a discretely-specified spatial function method developed at the Tashkent State Technical University. A comparison of the parameters obtained for a similar winding received by the pole amplitude modulation method has been presented. Design of a new motor with a new winding is developed based on the standard induction motor. The paper presents results of laboratory tests, too.}, type={Article}, title={Induction machine with pole-changing winding for turbomechanisms}, URL={http://journals.pan.pl/Content/127610/PDF/art08_int_corr2_AEE.pdf}, doi={10.24425/aee.2023.145417}, keywords={basic scheme of winding, differential leakage factor, Görges polygone, magnetizing forces, pole-changing winding, pole amplitude modulation, winding factor}, }
