Summary:To suppress an increase in the axial direction size of a motor.SOLUTION: A motor stator 4 has a core back 411, a plurality of teeth 412, a plurality of coil parts 43, and a crossover 45. The core back is arranged inside with respect to a magnet in the radial direction and surrounds a central axis. The plurality of teeth extends radially outward from the core back and is circumferentially aligned. In the plurality of coil parts, a conducting wire 44 is arranged in each of the teeth. The crossover is arranged radially inward with respect to the core back and electrically connects between different coil parts. The conducting wire has an extended part 441 that extends from the coil parts radially inward with respect to the core back. The extended part connects to the crossover.SELECTED DRAWING: Figure 1 【課題】モータの軸方向サイズの増加を抑制する。【解決手段】モータのステータ４は、コアバック４１１と、複数のティース４１２と、複数のコイル部４３と、渡線４５と、を有する。コアバックは、マグネットよりも径方向内方に配置され、中心軸を囲む。複数のティースは、コアバックから径方向外方に延びて周方向に並ぶ。複数のコイル部では、各々のティースに導線４４が配置される。渡線は、コアバックよりも径方向内方に配置され、異なるコイル部間を電気的に接続する。導線は、コイル部からコアバックよりも径方向内方に延びる伸長部４４１を有する。伸長部は、渡線と繋がる。【選択図】図１
