PROBLEM TO BE SOLVED: To provide a motor with a spacer, for positioning a stator core to a motor board easily in a shaft-line direction and around an axis of the shaft. SOLUTION: A spacer 10 is provided between a motor board 2 and a stator core 4 in a motor 1. The spacer 10 has an annular trunk part 11, projected parts 12a, 12b, 13a and 13b at the annular edges of the trunk part 11. The motor board 2 has grooves 21a and 21b for receiving the projected parts 12a and 12b, while the stator core 4 has grooves 31a and 31b for receiving the projected parts 13a and 13b. The spacer 10 is so provided that the projected parts 12a and 12b are embedded precisely in the grooves 21a and 21b. After that, when the stator core 4 is mounted in such a way that the projected parts 13a and 13b are embedded in the grooves 31a and 31b, the stator core 4 is positioned in a shaft-line direction and around the axis of the shaft automatically. In this way, the positioning work of the stator core 4 can be made easy. |
