STATOR AND MOTOR

To provide a technique compactifying a motor in an axial direction.SOLUTION: A motor comprises: a plurality of coil groups 40A, 40B, 50A, 50B, 60A and 60B arranged in an annular shape; and a substrate 70 having a plurality of wiring layers provided at one side of the coil groups along an axis line. The coil groups 40A and 40B are provided in order of first coil groups 40A and 40B, the second coil groups 50A and 50B, and the third coil groups 60A and 60B in a circumferential direction R1. A conduction direction of the first coil groups 40A and 40B is different from conduction directions of the second coil groups 50A and 50B and the third coil groups 60A and 60B. In the first coil groups 40A and 40B, first ends U3 and U21 of a second coil 42 and first ends U5 and U23 of a third coil 43 are electrically connected on a wiring layer 75, and second ends U2 and U20 of a first coil 41 and second ends U4 and U22 of the second coil 42 are electrically connected on a wiring layer 74.SELECTED DRAWING: Figure 7 【課題】軸線方向においてモータをコンパクト化する技術を提供する。【解決手段】環状に並ぶ複数のコイル群４０Ａ，４０Ｂ，５０Ａ，５０Ｂ，６０Ａ，６０Ｂと、軸線に沿ってコイル群の一方の側に設けられた複数の配線層を有する基板７０と、を備え、コイル群４０Ａ，４０Ｂは、一周方向Ｒ１に第１コイル群４０Ａ，４０Ｂ、第２コイル群５０Ａ，５０Ｂ、第３コイル群６０Ａ，６０Ｂの順に設けられており、第１コイル群４０Ａ，４０Ｂの通電方向は、第２コイル群５０Ａ，５０Ｂ及び第３コイル群６０Ａ，６０Ｂの通電方向とは異なる。第１コイル群４０Ａ，４０Ｂにおいて、第２コイル４２の第１端部Ｕ３，Ｕ２１と第３コイル４３の第１端部Ｕ５，Ｕ２３とは、配線層７５において電気的に接続されており、第１コイル４１の第２端部Ｕ２，Ｕ２０と第２コイル４２の第２端部Ｕ４，Ｕ２２とは、配線層７４において電気的に接続されていることを特徴とする。【選択図】図７
