STATOR CORE, METHOD OF STATOR MANUFACTURING AND ROTATING ELECTRICAL MACHINE Russian patent published in 2025 - IPC H02K1/18 H02K1/14 H02K15/95 

FIELD: electrical engineering.

SUBSTANCE: stator core 20 has a band first core 24 and a plurality of second cores 26. First core 24 has a plurality of first yoke-forming parts 24a and a plurality of connecting parts 24b, which connect the first yoke-forming parts 24a next to each other in the peripheral direction to each other. Second core 26 has a second yoke-forming portion 26a located in the middle between a pair of adjacent first yoke-forming portions 24a, and tooth-forming portion 26b, which protrudes inward in radial direction from first yoke-forming parts 24a. First yoke forming part 24a and the second yoke forming part 26a are connected to each other in the first connecting surface 40 and the second connecting surface 60. To achieve the technical result, connecting surfaces 40, 60 comprise corresponding planes 40a, 40b, 60a, 60b, which are inclined relative to the reference line L1 passing through the centre of the first yoke forming part 24a in the peripheral direction.

EFFECT: high strength of mutual attachment of elements of the split core of the stator.
