THREE-PHASED TWO-LAYERED ELECTRO-MECHANICAL WINDING WITH 2p=2c POLES WITHIN z=27c GROOVES 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 loop-like winding with 2p=2c poles within z=27c grooves is made of 6p alternating five- and four-coiled groups with concentric coils with their average groove step value being equal to y_c=9 and value c=1,2,3,... . Odd five-coiled groups with groove steps values being equal to 13-2(i-1) and even four-coiled ones with groove steps values being equal to y'_gi=12-2(i'-1) have coil numbers (1+x)w_c each for coils with i=1,2, i'=1,2, and (1-x)w_c coils for coils with i=4,5, i'=3,4, for w_c. Coils with i=3 have w_c coils. Within each grove 2w_c coils are present, i=1...5 and i'=1...4 - numbers of coils in groups, starting from external one, while x = 0,54.

EFFECT: decreased differential dissipation of σ_d m'=6-zoned electro-mechanical split (q=4,5) loop-like winding.
