摘要： A motor includes: a stator molded integrally with an insulating resin having a fixing member including a stator iron core and a winding wound thereon; a rotor arranged to face the stator about a shaft; a bearing rotatably supporting the shaft; a bracket fixing the bearing; and a drive circuit substrate having a drive circuit mounted thereon for driving the winding. The stator iron core is electrically connected to a ground serving as a reference point of a zero potential on the drive circuit substrate through a conductive member.
