Question Of The Week: VFD Induced Shaft Voltage Feedback Wanted

Best Practices For VFD Maintenance And Longevity

Posted by Heidi Schwartz

This week’s question comes from the Facilities Management Group group on LinkedIn.

question of the week logo.

I am looking for input from facility managers who have experience using a type motor VFD induced shaft diversion. In years past, I’ve seen various ads claiming to extend the life of motors/bearings by: diverting/absorbing/directing to ground and transient voltage caused by VFD induced shaft voltage.

Literature is everywhere with the newest widget to solve this problem, but is there a consistent reference that can address this industry gremlin?
