Abstract
A method for manufacturing an armature core is provided, in which a plurality of split cores, which are formed by laminating core pieces produced through punching by punching dies, are coupled together to form an annular shape as a whole, so as to manufacture one armature core. The method includes: preparing a plurality of sets of the split cores, each set having three split cores, so as to form one armature core; and arranging the three split cores in each set at intervals of 120° in the circumferential direction. The three split cores in each set are formed by core pieces that have been punched by the same part of the same punching die.

A method for manufacturing an armature core, wherein a plurality of split cores, which are formed by laminating core pieces produced through punching by punching dies, are coupled together to form an annular shape as a whole, so as to manufacture one armature core, the method comprising:
- preparing a plurality of sets of the split cores, each set having three split cores, so as to form one armature core, the three split cores in each set being formed by a plurality of core pieces that have been punched by the same part of the same punching die;
- and
- arranging the three split cores in each set at intervals of 120° in the circumferential direction.
A method for manufacturing an armature core, comprising:
- guiding a steel plate along a first direction, the steel plate having a plurality of areas that have a predetermined width and extend in a second direction perpendicular to the first direction;
- simultaneously punching a plurality of core pieces from each of the areas using each of a plurality of punching dies;
- forming a plurality of split cores by laminating core pieces produced through punching by the punching dies;
- forming one armature core by coupling the split cores together to form an annular shape as a whole;
- preparing a plurality of sets of the split cores, each set having three split cores, so as to form one armature core, the three split cores in each set being formed by a plurality of core pieces that have been punched by the same part of the same punching die;
- and
- arranging the three split cores in each set at intervals of 120° in the circumferential direction.
