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.

摘要： Provided is an electric motor driven by an inverter of PWM method, and devised to retard electrolytic corrosion in a bearing. A rotating body of a rotor comprises an outer iron core configuring an outer peripheral portion of the rotating body, an inner iron core configuring an inner peripheral portion connected to a shaft, a dielectric layer disposed between the outer iron core and the inner iron core, a plurality of insertion holes penetrating the outer iron core in the axial direction, and permanent magnets inserted individually in the plurality of insertion holes. It thus becomes possible to increase impedance of the rotor side (inner ring side of bearing) to approximate it to impedance of the stator side (outer ring side of the bearing) to thereby bring high frequency potentials balanced between the inner ring side and the outer ring side of the bearing, so as to provide the electric motor that retards electrolytic corrosion liable to occur in the bearing, and an electric device equipped with the same.
