NEXT GENERATION ELECTRIC MACHINES – Project Descriptions

You are here

On November 28, 2016, the U.S. Department of Energy announced nearly $25 million for 13 projects aimed at advancing technologies for energy-efficient electric motors through applied research and development. The Office of Energy Efficiency and Renewable Energy’s (EERE) Next Generation Electric Machinesprojects will address the limitations of traditional materials and designs used in electric motor components by cost-effectively enhancing their efficiency, improving their performance, and reducing weight. This effort will support innovative approaches that will significantly improve the technology in industrial electric motors, which use approximately 70 percent of the electricity consumed by U.S. manufacturers and nearly a quarter of all electricity consumed nationally.

Awardees are listed below.
