PROBLEM TO BE SOLVED: To provide a rolling bearing for an inverter suppressed in the generation of electric corrosion according to a drive frequency, an inverter motor using the rolling bearing, and an electric apparatus. SOLUTION: The bearing used for an inverter motor which operates at a frequency not lower than 50 Hz is characterized in that the bearing has a plurality of rolling bodies, and at least one or more rolling bodies have electric resistance values of not lower than 10<SP>7</SP>Ωcm by using insulative ceramics or insulative coatings. Thus, the generation of the electric corrosion is prevented. COPYRIGHT: (C)2011,JPO&INPIT |
