The coated advantage: Why using ceramic coated bearings makes sense
With the growing demand from industries to enhance the energy efficiency in their operations, inverter-controlled motors such as those featuring variable frequency drives (VFDs) are being increasingly favoured due to their versatility and control over operational speeds.
The uptake of inverter-controlled motors is expected to continue in the upwards direction as governments around the world mandate the use of energy-efficient products, with a global research predicting 6.5% annual growth in the global VFD market from 2020 to 2027.1
With the introduction of VFDs into an existing AC motor set up without any provision for grounding the shaft currents, there is a common bearing failure mode that occurs which is called Electric Erosion.
