After seeing many articles in magazines from many differnet vendors proclaiming VFDs as cost savers for items like HVAC (typically claiming 15% savings) do not ever seem to address the power factor issues of running a drive at some fraction of full load. By the time you add all the do-dads to fix the penalty you are going to create (depending upon the % of your total load made up by motors you are adding to VFDs) I have a hard time believing that you will come anywhere near that 15% they like to claim. In addition they do not have the tools for the end user to be able to determine if the upgrade will negatively affect their current power factor.
Or maybe it is just me that gets these stange request from customers that get hair brained ideas from the latest adds in whatever engineering magazine/website?
