FIELD: electric machine building. ^ SUBSTANCE: three-phase non-symmetric fractional winding at 2p=12.c poles in z=57.c grooves is made as double-layer m'=3-zone with number of grooves per pole and phase q=z/3p=19/6 from 18.c coil groups with numbers 1G...18G c and grouping of 433333343333334333, which is repeated c times. Concentric coils of groups have steps by grooves ygi=8, 6, 4, 2 with number of turns (1-x)wc, wc, wc, (1-x)wc for all four-coil and y'gi=7, 5, 3 with (1-x)wc, (1+x)wc, wc turns for all three-coil groups, where c=1, 2, 3,..., 2wc - number of grooves turns that are completely filled with winding, and value of x=0.52. ^ EFFECT: reduction of non-symmetric coefficient and differential scattering for m=3-phase, m'=m=3-zone non-symmetric loop fractional winding at 2p=12.c poles in z=57.c grooves and q=z/3p=19/6. ^ 4 dwg |
