Seminar 39 -- Efficiency Prediction of Motors and Variable Speed Drives with Compressors and with Fans

This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

"Extended product" is the jargon to mean a pump, compressor or fan, entirely packed with a motor, an optional mechanical transmission and an electronic variable-speed drive. The DOE prescribes motor test methods and had established mandatory minimum efficiencies, including certification requirements for motors as standalone components. The Canadian Standards Association’s standard CSA C838-13 Energy Efficiency Test Methods for Three-Phase Variable Frequency Drive Systems pioneered measurement of induction motors with VFDs. The Air Conditioning, Heating and Refrigeration Institute now offers rating certification for VFDs. This seminar discusses Alternate Efficiency Determination Methods (AEDMs) for practitioners, electric utility incentive program administrators and regulators to predict performance and efficiency for extended products from component data.
