Next Generation Electric Machines: Enabling Technologies


Manufacturing is the use of energy, equipment, information, services, and capital to convert raw materials, components, and parts into goods that meet market expectations. As an economic sector, manufacturing generates 12 percent of U.S. Gross Domestic Product (GDP) and employs 12 million Americans. The DOE Office of Energy Efficiency and Renewable Energy’s Advanced Manufacturing Office (AMO) makes research, development, and demonstration (RD&D) investments in advanced manufacturing process and materials technologies.

These technologies are foundational, pervasive, and promise crosscutting industrial applications and impact in reducing industry’s energy footprint and greenhouse gas (GHG) emissions, as well as supporting the global competitiveness of clean energy products. By targeting the development of energy-related advanced manufacturing technology, AMO’s work can create completely new supply chains and stimulate significant economic growth and job creation. AMO’s Next Generation Electric Machines (NGEM) program is an RD&D effort leveraging recent technology advancements in power electronics and electric motors to develop a new generation of energy efficient, high power density, high speed, integrated MV drive systems for a wide variety of critical energy applications. Improvements to these systems can be realized through the application of key enabling technologies, such as wide bandgap devices, advanced magnetic materials, improved insulation materials, aggressive cooling techniques, high speed bearing designs, and improved conductors or superconducting materials.

Through this development program, NGEM will facilitate a step-change that enables more efficient use of electricity, as well as reduced drive system size and weight, developing lasting capabilities for motor material development, design, and analysis that are cost-shared with industry stakeholders. This specific Financial Opportunity Announcement (FOA) is focused on advancing three key enabling technologies that can take the development of electric machines a giant step further by addressing significant reductions in three major categories of energy losses in an electric machine. The FOA leverages on recent technical advancements made in nanomaterial research, 6.5wt% siliconizing process in electrical steel manufacturing, and improved in-field performance of high temperature superconductor technology to realize the complete vision of developing a new generation of energy efficient, high power density, high speed electric machines for a wide variety of critical energy applications.
