    • In a rotary electric machine laminated core, a rotating shaft portion is disposed closer to an outer circumferential surface than an inner circumferential surface of a back yoke portion. A notch portion is disposed on at least one of first and second end portions of the back yoke portion so as to form a gap between a vicinity of the rotating shaft portion of a projecting portion and a recess portion when core segments are arranged in an annular shape or a circular arc shape. The first end portion and the second end portion of the back yoke portion are configured such that a predetermined gap that connects from the outer circumferential side to the inner circumferential side is formed between adjacent projecting portions and recess portions when the core segments are expanded rectilinearly such that magnetic pole tooth portions are parallel to each other.
    • 在旋转电机层叠铁心中,旋转轴部比背轭部的内周面靠近外周面配置。 在后轭部的第一端部和第二端部中的至少一方设置有切口部,以在芯部分布置成环状时在突出部的旋转轴部的附近与凹部之间形成间隙 形状或圆弧形状。 后轭铁部分的第一端部和第二端部被构造成使得当芯部段被直线地扩展时,在相邻的突出部分和凹部之间形成从外周侧到内周侧连接的预定间隙 磁极齿部彼此平行。
