Title:
ROTATING ELECTRIC MACHINE ARMATURE CORE AND ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/145631
Kind Code:
A1
Abstract:
The present invention provides a rotating electric machine armature core and a rotating electric machine such that material yield and productivity can be enhanced without degrading the characteristics of a rotating electric machine even when the width-enlarged portion of a magnetic pole tooth is increased in width dimension. In a linearly expanded divided-iron-core connected body, the distance between adjacent width-reduced portions is larger than the width dimension of a width-enlarged portion when the adjacent divided iron cores are at an enlarging position, and the distance between the adjacent width-reduced portions is smaller than the width dimension of the width-enlarged portion when the adjacent divided iron cores are at a reducing position. When the distance between the center lines of adjacent magnetic pole teeth that are at the enlarging position is denoted by τs', the width dimension of a tooth main portion by te, and the width dimension of the width-reduced portion by tn, the divided-iron-core connected body is constructed so as to satisfy the relationship of (te - tn)/τs' > 0 and 0 < (te - tn)/te ≤ 0.27.
