Abstract
A laminated core having a first number of magnetic poles, the first number being a natural number divided by two, of a rotary electric machine, includes a plurality of arc-shaped unit cores each having a second number of magnetic poles, the second number being a natural number except for an aliquot part of the first number. The unit cores are wound and laminated a predetermined number of times in a circumferential direction into a spiral shape in such a manner that an axial lamination amount of the unit cores is obtained by an equation of X=θ*t/360, X being the axial lamination amount, θ being a winding angle of the unit cores, and t being a thickness of the unit core. The unit cores are adjacent to each other in the circumferential direction connected to each other at a part of an outer circumference thereof.
