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.

摘要： A motor includes a stator having a stator iron core wound with stator windings, a rotor rotatably mounted on a shaft, a bearing for supporting the shaft, and a conductive bracket for fixing the bearing. The rotor is formed of a rotary body that holds a permanent magnet and the shaft that extends through the rotary body at center and joined to the rotary body. An electrostatic capacity between the shaft and an outermost wall of the rotary body is set smaller than an electrostatic capacity between an inner ring and an outer ring of the bearing during rotation of the bearing.

摘要： An electric motor includes a stator that has a stator winding wound on a stator iron core; a rotor having a rotating body with a rotating shaft in the center; a bearing for journaling the rotating shaft; and two conductive brackets for fixing the bearing. The rotating body holds a magnet such that the magnet faces the stator, and is fastened to the rotating shaft penetrating through the center of the rotating body. In the rotating body, a dielectric layer is formed between the rotating shaft and the outer circumference of the rotating body. The dielectric layer has a polygonal shape with the rotating shaft in the center. An electric device includes the thus configured electric motor.

摘要： A stator, a rotor, bearings, and conductive brackets are provided. The stator has a stator iron core having a winding wound thereon. The rotor has a rotating body that holds a permanent magnet in the circumferential direction so that the permanent magnet faces the stator, and a shaft that has the rotating body fastened thereto so as to penetrate through the center of the rotating body. Both of the bearing on the output shaft side and the bearing opposite the output shaft side journal the shaft. One of the brackets fixes the bearing on the output shaft side, and the other of the brackets fixes the bracket opposite the output shaft side. The brackets are electrically connected to each other, and a dielectric layer is formed between the shaft and the outer periphery of the rotating body.
