FIELD: electric engineering, possible use for technologies of electro-mechanical engineering, engineering and production of three-phased asynchronous and synchronous devices. ^ SUBSTANCE: three-phased two-layered electro-mechanical winding having 2p=14 poles within z=108 grooves and with q=18/7 with grouping of coils in accordance with row 3 3 2 3 2 3 2, repeated further for 6 times, is made of 6p=42 coil groups with numbers 1Gamma,... 42Gamma, with opposite connection of even coil groups in phases relatively to odd ones and with average step of coils across grooves being equal to value yc=6. In accordance to the invention, in first grouping 1Gamma,...7Gamma first coil of groups 1Gamma,6Gamma and third coil of groups 2Gamma,4Gamma, groups 1Gamma,2Gamma,4Gamma,6Gamma with groove step value being equal to yg=6 have (1-x)wc coils each. External coils of concentric groups 3Gamma,5Gamma,7Gamma with groove step value being equal to yg=7,5 have (1+x)wc coils each, while remaining coils of groups have wc coils each. Distribution of not even-coiled coils with coils unevenness coefficient being equal to value x=0,40, as described in detail above, is repeated for each following grouping of coils in accordance with aforementioned row. ^ EFFECT: decreased differential dissipation. ^ 4 dwg |
