This diagnostic guide details how to distinguish VFD-induced electrical bearing damage from mechanical failure through visual inspection of fluting, vibration analysis, and shaft voltage testing.

Choosing the right bea…

This buyer’s guide explains the critical role of insulated bearings in protecting VFD-driven motors, comparing the technical benefits of Plasma-Coated versus Hybrid Ceramic solutions and detailing best practices for installation (DE vs. NDE) to prevent circulating currents.

This technical analysis explains how VFD switching creates destructive high-frequency bearing currents, detailing the difference between EDM and circulating currents, and offering mitigation strategies like proper grounding and insulated bearings.
