FIELD: electric engineering and electro-mechanical industry, possible use for construction of three-phased asynchronous and synchronous electric machines. ^ SUBSTANCE: three-phased split (q=6,75) winding of electric machines is made with grouping 7 7 7 6, two-layer 2p=8c-polar in z=81c grooves of 12c coil groups with numbers 1Gamma...12(c)Gamma with concentric coils with their average step by grooves yc=10, integer number c=1,2,..., numbers i',i=1...7 coils in groups, starting from external one, 2wc coils of each groove. In accordance to invention, in groups 1Gamma...4Gamma of first grouping, seven-coil groups have coil steps ygi=16-2(i-1) with coil number (1-x)wc in i=7 of groups 1Gamma, 3Gamma and in i=1 of group 2Gamma, (1+x)wc in i=4 of group 2Gamma, and six-coiled 4Gamma-y'gi=15-2(i'-1) with coil numbers (1+x)wc in i'=3 and 4 for wc coils in remaining coil groups, while aforementioned distribution of not even-coiled coils is repeated in next grouping, where x=0,48. ^ EFFECT: decreased differential dissipation sigmaD of m'=3-zoned split (q=z/3p=6,75) winding. ^ 3 dwg |
