Motors and VFDs: How They Work, When They Don't, and What You Can Do

This presentation will first review the theory of operation for electric motors and variable frequency drives (VFD), including making the business case for switching to premium efficient motors and employing VFDs. We will then consider the many failure modes of both motors and VFDs, especially the failures that are caused by their interaction. Root causes will be reviewed along with solutions for each failure mode. Actual examples from industrial applications will be presented.
