description FIELD: electric radio engineering and electric mechanical engineering, possible use in three-phase asynchronous and synchronous electric machines. ^ SUBSTANCE: three-phase two-layer split (q=4,75) winding is made 2p=8c-polar two-layered with grouping 5 5 5 4 in z=57c grooves of 12c coil groups with numbers 1Gamma...12(c)Gamma with concentric coils having average step by grooves yc=7, integer value c=1,2,..., numbers i',i=1...5 coils in groups, starting from outer one, 2wc of each groove. In accordance to invention, in groups 1 Gamma...4 Gamma of first grouping five-coil groups have coil steps ygi=11-2(i-1) with coil numbers (1-x)wc in i=5 of groups 1Gamma,3Gamma and in i=1 of group 2Gamma,(1+x)wc in i=3 of group 2Gamma, and four-coil one 4Gamma - y'gi=10-2(i'-1) with coil numbers (1+x)wc in i'=2 and 3 for wc coils in remaining coils of groups, while said distribution of not even-coil coils is repeated in each following grouping, where x=0,48. ^ EFFECT: decreased differential dissipation sigmad of symmetric m'=3-zone split (q=z/3p=4,75) winding. ^ 3 dwg
