IE2 IE3 efficiency and VFDs
IE2 IE3 efficiency and VFDs
(OP)
Dear all,
premium efficiency IE3 async motors will be mandatory next year in many countries (U.S. already by 2011, others later). I wonder if driving an IE2 motor with a VFD will be considered acceptable or not. In my opinion the savings in starting and stopping cycles may justify this approach. I'm not looking for legal advice, just a technical point of view.
Thank you for your suggestions.
