STATOR CORE OF ROTARY ELECTRIC MACHINE AND PRODUCTION METHOD FOR STATOR CORE OF ROTARY ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To provide a stator core of a rotary electric machine in which disturbance of coil winding can be prevented, and a production method for the stator core of the rotary electric machine.SOLUTION: In each divided core 11 of a stator core 10 of a rotary electric machine having a tooth part 12 and a back yoke part 13, a plurality of core members 2 composed of electromagnetic steel sheets are formed so as to be layered in an axial direction Y. The core members 2 include, in the back yoke part 13, a first recessed and projected portion 3 for connecting the core members 2 adjacent in the axial direction Y. A first core member 21 has no recessed and projected portion formed in the tooth part 12, and a second core member 22 has, at a position where a coil 8 is disposed on the tooth part 12, a second recessed and projected portion 4 having a recess/projection height H2 lower than a recess/projection height H1 of the first recessed and projected portion 3. On the axial direction Y side where the projection of the second core member 22 is formed, the first core member 21 is layered so as to have a base surface of the tooth part 12 of the first core member 21.SELECTED DRAWING: Figure 6 【課題】コイルの巻乱れを防止できる回転電機のステータコアおよび回転電機のステータコアの製造方法を提供する。【解決手段】ティース部１２とバックヨーク部１３とを有する回転電機のステータコア１０の分割コア１１において、電磁鋼鈑にて成るコア部材２が軸方向Ｙに複数枚積層して形成され、コア部材２は、バックヨーク部１３に軸方向Ｙに隣接するコア部材２同士を接続する第一凹凸部３を有し、第一コア部材２１はティース部１２に凹凸部を形成せず、第二コア部材２２は、ティース部１２のコイル８の配置箇所に第一凹凸部３の凹凸高さＨ１より凹凸高さＨ２の低い第二凹凸部４を有し、第二コア部材２２の凸部が形成される軸方向Ｙ側には、第一コア部材２１が積層され第一コア部材２１のティース部１２の基礎面を有する。【選択図】図６
