FIELD: electric radio engineering and electric mechanical engineering, possible use in three-phase asynchronous and synchronous electric machines.
SUBSTANCE: three-phase two-layer split (q=3,5) winding is made 2p=4c-polar in z=6cq grooves of 6c coil groups with four-coil odd and three-coil even ones with average step of concentric coils yc≈z/2pc. In accordance to invention, four-coil groups have coil steps ygi=8,6,4,2 with coil numbers (1-x)wc,(1+x)wc,wc,(1-x)wc, and three-coil ones - y'gi=7,5,3 with coil numbers wc,(1+x)wc,wc, where c=1,2,3,..., - integer number, z=21c, yc=1,5q-0,25=5 and 2wc - number of coils of each groove for value x=0,54.
EFFECT: better composition of harmonic operation ampere-turns, decreased differential dissipation σd of symmetric m'=3-zone split (q=z/3p=4,25) winding.
