THREE-PHASED TWO-LAYERED ELECTRO-MECHANICAL WINDING WITH 2p=2c POLES WITHIN z=21c 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=21c grooves is made of 6p alternating four- and three-coiled groups with concentric coils with their average groove step value being equal to y_c=7 and value c=1,2,3,... . Odd four-coiled groups with groove steps values being equal to y_c=10-2(i-1) and even three-coiled ones with groove steps values being equal to y'_gi=9-2(i'-1) have coil numbers (1+x)w_c each for coils with i=1,2, i'=1, and (1-x)w_c coils for coils with i=3,4, i'=3. Coils with i'=2 have (1-x)w_c coils. Within each grove 2w_c coils are present, i=1...4 and i'=1...3 - numbers of coils in groups, starting from external one, while x = 0,57.

EFFECT: decreased differential dissipation of σ_d m'=6-zoned electro-mechanical split (q=3,5) loop-like winding.
