To suppress flux leakage flowing through an end portion of an inner peripheral side of tooth of a stator core.SOLUTION: A stator core 11 has a tooth group 11a in which a plurality of teeth 11a2 are arranged annularly and both of adjoining teeth 11a2 are connected by a thin connection portion 11a1 provided in an inner peripheral side tip portion, and an annular yoke portion 11b within which the tooth group 11a is arranged. The thin connection portion 11a1 has a concave 11a6 whose thickness in a plate thickness direction is thinner than other portion.SELECTED DRAWING: Figure 4A
【課題】固定子鉄心のティースの内周側の端部に流れる漏れ磁束を抑制する。【解決手段】固定子鉄心11は、複数のティース11a2が環状に配置されるとともに、隣接するティース11a2同士が内周側先端部に設けられた薄肉連結部11a1によって連結されたティース群11aと、ティース群11aが内部に配置される環状ヨーク部11bとを備え、薄肉連結部11a1は、板厚方向の厚さが他の部分より薄い凹み11a6を有している。【選択図】図4A
