Inverter controlled motors in Fans have progressed in recent years but this has created voltage variations which causes current to flow through the bearing, creating damage inside the bearing from electrical corrosion. In order to prevent these damages NSK has created a new anti-electrical corrosion bearing, using balls made from an innovative ceramic material.
