FIELD: electric engineering and electro-mechanical industry, possible use for construction of three-phased asynchronous and synchronous electric machines. ^ SUBSTANCE: three-phased split (q=3,75) winding of electric machines is made with grouping 4 4 4 3, two-layer 2p=8c-polar in z=45c grooves of 12c coil groups with numbers 1Gamma...12(c)Gamma with concentric coils with their average step by grooves yc=6, integer number c=1,2,..., numbers i',i=1...4 coils in groups, starting from external one, 2wc coils of each groove. In accordance to invention, in groups 1Gamma...4Gamma of first grouping, four-coil groups have coil steps ygi=9-2(i-1) with coil number (1-x)wc in i=4 of groups 1Gamma, 3Gamma and in i=1 group 2Gamma, (1+x)wc in input=3 of group 2Gamma, and three-coiled 4Gamma-y'gi=8-2(i'-1) with coil numbers (1+x)wc in i'=2 and 3 for wc coils in remaining coil groups, while aforementioned distribution of not even-coiled coils is repeated in next grouping, where x=0,47. ^ EFFECT: decreased differential dissipation sigmaD of m'=3-zoned split (q=z/3p=3,75) winding. ^ 3 dwg |
