FIELD: electricity. ^ SUBSTANCE: present invention pertains to electric machine engineering. The invention seeks to simplify manufacturing and increase use of active materials, while reducing input of insulating materials and coefficient of differential scattering âd% m=3-phase 2p1=6k- and 2p2=8k- pole lap windings of a stator in z=144k slots. The essence of the invention lies in that, the double-winding stator of an asynchronous motor has m=3-phase 2p1=6k- and 2p2=8k-pole lap windings in z=144k slots, each of which is made symmetrical from m=6-zone from equally spaced coils, put into the slots in two layers. According to this invention: from K=z coils with numbers from 1K to (z)K, the 2p1 pole winding relates to K/2 coils with odd numbers 1K, 3K,Ç(z-1)K, containing wK1 turns and connected into 6p1 coil semi-groups with q'1=4 neighbouring coils in each. The 2p2 pole winding relates to K/2 coils with even numbers 2K, 4K,Ç,(z)K, containing wk2 turns and connected into 6p2 coil semi-groups with q'2=3 neighbouring coils in each. All coils have uneven spacing in the slots, equal to yk=19, or yk=21, where k=1, 2 given q'1=z/12p1 and q'2=z/12p2. ^ EFFECT: easier manufacturing and increases use of active materials, while reducing input of insulating materials and coefficient of differential scattering. ^ 3 dwg |
