FIELD: electrical engineering. SUBSTANCE: mush concentric winding of electric machine is of single-double layer type. Even number of slots are filled in one layer by conductors of one phase in coil group. Ratio is given in description of invention. Main element of winding, which is turn, is shortened both in slot pitch and in end portion length. Invention makes it possible to provide uniform skewing of coil groups both at even and odd numbers of slots per pole and phase and at unequal values of number of slots in winding phases. EFFECT: facilitated repairs of electric machines. 3 dwg
