摘要： PROBLEM TO BE SOLVED: To solve a problem such as that, though a magnetic plate is provided with a die-cut caulking so as to prevent magnetic plates from slipping from one another in the case of laminating magnetic plates, thereby making them into a stator for a rotating-electric machine, the die-cut caulking breaks the insulating layer of the magnetic plate and an eddy current path is made via this broken part and eddy current loss increases, and that if the die-cut caulking at a tooth is eliminated to reduce the eddy current loss, the space between lamination layers narrows after winding and the core deforms.
SOLUTION: The die-cut caulking 2 (the first concavo-convex part) is provided only at a core-back part 4, and the tooth 5 is provided with the second concavo-convex part 3. Since the second concavo-convex part 3 is shaped such that it does not have an edge, the insulating layer 26 of the magnetic plate 20 is never broken. Moreover, the radius R of a convex 3b is larger than the radius r of the concave 3a of the second concavo-convex part 3, so when they are laid on tops of one another, proper space 27 arises between a plate and a plate. Consequently, the space between the laminated magnetic plates 20 can be secured, while keeping the insulation between the lamination layers.

摘要翻译：要解决的问题为了解决这样一个问题，即在磁性板设置有模切铆接，以便在层叠磁性板的情况下防止磁性板彼此滑动，从而使它们进入旋转电机的定子中，冲切铆接破坏了磁板的绝缘层，并且通过该断开部分形成了涡流通路，并且涡流损耗增加，并且如果在一个齿被消除以减少涡流损耗，层压层之间的间隔在卷绕之后变窄并且芯变形。解决方案：模切铆钉2（第一凹凸部）仅设置在芯背部4处，并且齿5设置有第二凹凸部3.由于第二凹凸部2，凸部3成形为不具有边缘，磁性板20的绝缘层26不会断裂。此外，凸部3b的半径R大于第二凹凸部3的凹部3a的半径r，因此当它们被放置在彼此的顶部上时，在板和板之间产生适当的空间27。因此，可以确保层叠磁性板20之间的间隔，同时保持层压层之间的绝缘。版权所有（C）2008，JPO＆INPIT
