Electric motors in HVAC systems are often controlled by variable frequency drives, to save energy by running the motors only as fast as necessary.  But these drives cause electrical bearing damage and premature motor failure.  In this webinar, we look at electrical bearing protection in HVAC applications.

The contents of the training include:

  • Bearing frosting, fluting, & failure
  •  Motor shaft voltage and bearing current 
  • Detection of shaft voltage
  • Shaft grounding best practices for bearing protection
