Electrical Bearing Protection for Large Motors

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 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
