Quiz: How does your preventive maintenance program handle VFD-driven stress on bearings?

Variable frequency drives (VFDs) can unlock major efficiency gains, but they can also introduce electrical and mechanical stresses that quietly erode bearing life. From circulating currents to improper grounding and motor shaft voltage, the risks often remain hidden until a failure halts production.

This quiz puts your knowledge of VFD-related bearing issues to the test. See if you can spot early warning signs, choose the right mitigation strategies, and strengthen your preventive maintenance program before small problems become costly downtime.
