THREE-PHASE STATOR ASSEMBLY Russian patent published in 2022 - IPC H02K1/14 H02K3/28 H02K3/52 H01R4/2416 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the node (1) of the three-phase stator of the drive motor of the electric pump. The stator assembly (1) contains three sets of segments (S_{i, j}) placed in an annular arrangement around the stator axis (R) extending in the axial direction. Each set of segments (S_{i, j}) contains n ≥ 2 segments (S_{i, j}), with each specified segment (S_{i, j}) containing a coil (3) having a first end (5) and a second end (7) of the coil wire, and a plurality of 3n-3 connecting wires (W_{i, k}) placed on the axial front side (9) of the segments (S_{i, j}). Each connecting wire (W_{i, k}) connects two coils (3) of the corresponding set of segments (S_{i, j}) in series, while the first intermediate segment (S_{i, j}) and the second intermediate segment (S_{i, j}) of the other two sets of segments (S_{i, j}) are placed in a circular direction between two connected coils (3) of the specified set of segments (Si, j). At least 3n-5 connecting wires (W_{i, k}) pass through the first intermediate segment (S_{i, j}) at the first radial distance (r₁) to the stator axis (R) and through the second intermediate segment (S_{i, j}) at the second radial distance (r₂) to the axis (R) of the stator. The second radial distance (r₂) is greater than the first radial distance (r₁).

EFFECT: improving the manufacturability of the stator.
