in motors used in general industrial machinery, use of inverter control is expanding in order to increase efficiency. along with this development, cases of a type of damage called have been seen in bearings.
one way to prevent electric corrosion is to use non-conductive ceramic balls in bearings. however, productivity then becomes an issue. it is also possible to include an insulated housing in the motor, but this requires special parts and assembly processes. to solve these issues, has developed a new that is highly productive and compatible with standard.
electric corrosion:
when an passes along the contact point of the bearing races and rolling elements while the bearing is rotating, sparks are generated in the thin lubricant film and that surface is locally fused into an uneven shape.
