ELECTRIC MOTOR |
| 摘要 |
An electric motor includes: a rotating shaft; a rotor securely attached to the rotating shaft and including a cylindrical magnet portion; a stator formed in an annular shape on an outer peripheral side of the rotor; a board installed above the rotor and the stator with a predetermined air gap therefrom; and a lead wire connected to the board. A connecting portion of the board and the lead wire is formed at a position on an inner side of an axial projection plane of the magnet portion of the rotor above the board. In this electric motor, even when the rotor is increased in diameter, the connecting portion of the lead wire connected to the board can be prevented from being located proximate to an upper part of the magnet portion of the rotor. |
