SPLIT STATOR CORE, STATOR COMPRISING THE SAME SPLIT STATOR CORE, ROTARY ELECTRIC MACHINE COMPRISING THE SAME STATOR, AND METHOD FOR MANUFACTURING SPLIT STATOR CORE

摘要

PROBLEM TO BE SOLVED: To provide a configuration that improves the material yield of a split stator core in a stator made by combining a plurality of split stator cores in a circle.SOLUTION: A split stator core 30 is integration of an arcuate yoke 1 and magnetic pole teeth 2. The magnetic pole teeth 2 project from an inner peripheral part 1b of the yoke 1 toward an inner diameter side, and is provided with a tip 2a extending in the circumferential direction. A notch 1f provided at an inner peripheral part 1a of the yoke 1 extends from the side surface of the magnetic pole teeth 2 to an arc end surface 1k of the yoke 1. The split stator core 30 makes it possible to form a split stator 50 of which an insertion piece 3 is fit into the notch 1f.
