QIBR develops insulated bearings for inverter motors
One way to prevent electric corrosion is to use non-conductive ceramic balls in the bearings However this can have a negative effect on productivity Another option is to deploy an insulated housing in the motor but this requires special parts and assembly processes
Bearing currents and how to beat them
Both bearings must be insulated or the bearing current effect will be focused on the non-insulated bearing and it will fail twice as quickly We also recommend using hybrid bearings that will offer benefits such as low friction longer re-lubrication intervals and a longer lifetime compared to a standard bearing
