February's Problem

Dec. 10, 2009
We always used stepper motors in our semiconductor processing machinery with great success, but we're looking to cut costs. I've heard that it's possible to combine some of the newer VFDs with standard induction motors and attain performance close to stepper levels for less money. Does anyone have any experience with this type of an application? If so, what are the pluses and minuses?
