By allowing precise control of motor speed or torque, variable frequency drives (also known as variable speed drives or inverters) can improve process control and can save 30% or more in energy costs.  But VFDs induce voltages on the shafts of the motors they control – voltages that can discharge through bearings, destroying them in as few as 3 months!

This webinar discusses how plant maintenance can channel these harmful currents away from bearings and safely to ground, protecting motor bearings (and those of attached equipment) and allowing motors to last for the full L-10 life of their bearings.

Learning Objectives:
(Key Takeaways)

  1. Review why VFDs are so widely used
  2. Learn how VFDs can damage motor bearings
  3. Understand the advantages/drawbacks of various shaft grounding technologies
  4. Find out how effective shaft grounding can protect motor bearings for their full L-10 life
  5. Learn the different ways to equip motors with effective shaft grounding
