STATOR WINDING OF THREE-PHASE MOTOR Russian patent published in 2005 - IPC

FIELD: electromechanical engineering; multipole induction motors.

SUBSTANCE: proposed stator winding has twelve pairs of coaxial different-pitch single-layer and double-layer coils placed in 36 slots at stator pole pairs 2p = 20. External ones are double-layer coils; finishing leads of double- and single-layer coils of each pair are interconnected. Starting lead of single-layer coil in pair (4i-3) is connected to starting lead of single-layer coil of pair 4i; starting lead of double-layer coil of pair 4i is connected to starting lead of double-layer coil (4i+3); starting lead of single-layer coil of pair (4i+3) is connected to starting lead of single-layer coil of pair (4i+6). Phase leads are formed from starting leads of double-layer coils of pair (4i-3) and starting leads of double-layer coils of pair (4i+6) are interconnected to form neutral point (i = 1, 2, 3; number 12 is subtracted from numbers greater than 12).

EFFECT: enlarged functional capabilities.
