Electric motors on variable frequency drives are at risk of electrical bearing damage. This webinar discusses special considerations for protecting large motors (over 500 hp/375kW) from bearing current.

This webinar will be presented by Andy Kressbach, North American Sales Manager for AEGIS® Shaft Grounding Rings, and Mike Pulley, VP, Sales Operations, of Bartlett Bearing Company.

This training is worth one Professional Development Hour. For licensed engineers, Electro Static Technology is a listed provider on the NCEES CPC Registry.

In this webinar, you will learn:

• Shaft grounding best practices for large motors (over 500 hp/375 kW or 600V)
• The risk of VFD-sourced shaft voltages, bearing current, and electrical bearing damage
• Bearing frosting, fluting, & failure
• Detection of motor shaft voltages
