Three-phase asymmetric fractional winding at 2p = 6 with poles in z = 42 grooves, performed by a two-layer m ′ = 3-zone with the number of grooves per pole and a phase q = z / 3p = 14/3 of 3p from coil groups with a group of 545455554, repeated with times, characterized in that the concentric coils have _groove steps y _pi = 1l-2 (i-1) with the number of turns (1-x) w _to coils with i = 1,5 and (1 + x) w _to , coils with i = 3 for all five-coil groups, y ′ _pi = 10-2 (i′-1) with the number of turns (1 + x) w _{to the} coil with i ′ = 3 for all four-coil groups with w _{to the} turns in the remaining coils of the groups , where c = 1, 2, 3, ..., i ′ = 1 ... 5 and i ′ = l ... 4 are the numbers of the coils of the groups another with the outside, x = 0.55 and 2w _to - the number of turns of the grooves, completely filled with a winding.
