Abstract

PURPOSE:To equalize all adjacent magnetic area, and to improve electrical characteristics by making a pitch P between slots simultaneously punched pi.(Ri+ Ro)/n (n: the number of slots and Ri, Ro: the inside diameter and outside diameter of the wound core). CONSTITUTION:When the slot pitch between the slots simultaneously punched is made P, the number of the slots n and the inside diameter of the wound core wound and laminated Ri and the outside diameter Ro, the slot pitch is determined so that P pi.(Ri+Ro)/n is formed. The area of a pole-face 13 held by the slot 11 simultaneously punched and the adjacent slot 12 punched at the same time is approximately the same as that of a pole-face 14 held by the mutual slots simultaneously punched. Accordingly, the distribution of magnetic flux in an air gap is improved and the electrical characteristics are ameliorated.

2. Description of the Related Art Conventionally, in order to reduce the manufacturing cost of a double-wound core used in an axially gap type rotating electric machine, a method is known in which a plurality of slots are punched out at the same time. However, the wound core obtained by this manufacturing method is
As is clear from FIG. 1, the magnetic pole faces of the wound laminated core did not all have the same shape, and generally adjacent magnetic pole faces were different. In other words, in general, the magnetic pole face 3 sandwiched between simultaneously punched slots 1 (the slot pitch is constant) and the adjacent simultaneously punched slots 2 is the same as the magnetic pole face 4 sandwiched between simultaneously punched slots. There was a difference in area. As a result, the magnetic flux distribution becomes non-uniform, resulting in distorted waves including harmonics, which has the disadvantage of causing deterioration of electrical characteristics such as an increase in input and input current, an increase in vibration noise, and an increase in temperature.
