Document Type and Number:
WIPO Patent Application WO/2021/024318
Kind Code:
A1
Abstract:
This electric motor stator core has a plurality of divided cores disposed annularly. The plurality of divided cores respectively make contact with adjacent another divided core through mutual contact surfaces, thereby forming a plurality of contact portions in the circumferential direction. The mutual contact surfaces of at least one of the plurality of contact portions have linear portions extending linearly in the radial direction when viewed in the central axis direction of the stator core. In addition, one of the mutual contact surfaces has a triangle-shaped protrusion portion, and the other has a triangle-shaped recessed portion. The mutual contact surfaces are connected in such a way that the linear portions are contacted with each other and the triangle-shaped protrusion portion and the triangle-shaped recessed portion are engaged with each other.
