THREE-PHASE SPLIT (q=2,75) WINDING OF ELECTRIC MACHINES Russian patent published in 2005 - IPC

Abstract RU 2267212 C2

FIELD: electric engineering and electro-mechanical industry, can be implemented in three-phase asynchronous and synchronous electric machines.

SUBSTANCE: three-phase split (q=2,75) winding of electric machines is made with grouping 3 3 3 2 two-layer 2p=8c-polar in z=33c grooves of 12c coil groups with numbers 1Γ...12(c)Γ with concentric coils with their average step of grooves yc = 4, integer number c = 1, 2, ..., numbers i', i = 1...3 coils in groups, starting from external one, 2wc coils of each groove. Also, in accordance to invention, in groups 1Γ...4Γ of first group three-coil groups have coil steps yπi = 6 - 2(i - 1) with coil numbers (1 - x)wc in i = 3 of groups 1Γ, 31 and in i = 1 group 2Γ, (1+x)wc in i=2 group 2Γ, and two-coil 4Γ-y'πi = 5-2 (i'-1) with coil numbers (1+x)wc each for wc coils in remaining coils of groups, while said distribution of not even-coiled coils is repeated in each following group, where x=0,48.

EFFECT: decreased differential dissipation σd of m' = three-zone split (q=z/3p=2,75) winding.
