Wednesday, June 19, 2024 11:00 AM - 12:00 PM EDT 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](http://www.bartlettbearing.com/). 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   ##### Register Now!
