Permanent magnet materials: An assessment of the state of the art. Final report
- Daedalus Associates, Inc., Mountain View, CA (United States)
Permanent magnets underlie many of the technologies that are central to modern industrial societies, including electric motors. Given that electric motors consume approximately 62% of the total electricity generated in the United States each year, they are considered one of the most promising applications of high-efficiency permanent magnet materials. In particular, a new class of permanent magnets composed of rare-earth (RE) and transition-metal (TM) elements is expected to have a major impact on electric motor efficiency and the electric power industry. EPRI has conducted a thorough review of the literature on permanent magnet materials to summarize their status and potential, with a focus on applications to electric motors technologies. This report summarizes and discusses issues that are key to the successful application of new permanent magnetic materials in electric motors, including design innovations in large electric motors and the economical and political limitations on raw materials. Finally, areas of future research are outlined.
