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.

摘要： A two-piece motor stator having; a generally annular inner iron stator core having a plurality of teeth extending radially outwardly from outer surface thereof, an annular outer iron stator core having slots in the inner surface thereof for receiving tip portions of the teeth, and coils provided around body portions of the teeth respectively before the inner and outer iron cores are combined together by press fitting, wherein the outer iron stator core has a plurality of channels made in the inner surface, the channels being formed along each of the slots for absorbing stress resulting from press fitting the tip portions into the slots in order to reduce the degree of deformation of the inner and outer stator iron cores. The channels may be made in the tip portions of the teeth instead of the inner surface of the outer iron stator. The channels also may be filled with a deformable and magnetically soft material.
