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=14c poles within z=75c grooves with grouping of coils in accordance with row 4 4 3 4 3 4 3, repeated further for 3c times, is made of 3p=21c coil groups with numbers 1Gamma,... 21(c)Gamma, with serial and matching connection of groups in phases and average step of concentric coils across grooves being equal to value yc=5. In accordance to the invention, in first grouping 1Gamma,...7Gamma inner coils of groups 1Gamma,2Gamma,4Gamma,6Gamma, while groove steps are equal to value ygi=8,6,4,2, have (1-x)wc coils each, and middle coils of groups 3Gamma,5Gamma,7Gamma, while groove steps are equal to value y'gi=7,5,3, 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=0,65, as described in detail above, is repeated in each following grouping of coils in accordance with aforementioned row, while c=1,2,3. ^ EFFECT: decreased differential dissipation. ^ 4 dwg |
