THREE-PHASED TWO-LAYERED ELECTRO-MECHANICAL WINDING WITH 2p=14, z=96, q=16/7 Russian patent published in 2006 - IPC H02K3/28 H02K3/04 

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=96 grooves and with q=16/7 with grouping of coils in accordance with row 3 2 2 3 2 2 2, repeated further for 6 times, is made of 6p=42 coil groups with numbers 1Γ,... 42Γ, 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 y_c=6. In accordance to the invention, in first grouping 1Γ,...7Γ inner coils of groups 1Γ,4Γ with groove step values being equal to y_gi=8,6,4 and groups 2Γ, 3Γ, 5Γ, 6Γ, 7Γ with groove step values being equal to y'_gi=7,5 have (1-x)w_c coils each, while remaining coils of groups have w_c coils each. Distribution of not even-coiled coils with coils unevenness coefficient being equal to value x=0,46, as described in detail above, is repeated for each following grouping of coils in accordance with aforementioned row.

EFFECT: decreased differential dissipation.
