Abstract:
1. A windingly laminated core of a rotary electric machine, having a first number of magnetic poles in total, the first number being a natural number that is dividable by two, comprising: a plurality of unit cores, each of the plurality of unit cores having an arc and thin plate shape and having a second number of magnetic poles, the second number being a natural number except for an aliquot part of the first number and being less than the first number and being equal to or more than three; and an adjustment unit core having the arc and thin plate shape; wherein a winding lamination is applied to the unit cores in a circumferential direction and in a spiral manner so as to form a cylindrical shape, wherein a lamination thickness in an axial direction of the winding lamination is set to a predetermined thickness, wherein the adjustment unit core is arranged at at least one of a start and an end of the winding lamination, in a circumferential direction such that a rotational phase of the start of the winding lamination is aligned to correspond to a rotational phase of the end of the winding lamination, and wherein the adjustment unit core has a third number of magnetic poles that is less than the second number.
