摘要

Many kinds of permanent magnet materials have been applied in Motor Drive Systems. The most important examples have been permanent magnet rotors for Interior Permanent Magnet Synchronous Motor (IPMSM) and Surface Permanent Magnet Synchronous Motor (SPMSM) to improve motor efficiency and make their sizes smaller. In this chapter, the measurement methods for permanent magnet materials are reviewed to contribute to developments for high-performance Motor Drive Systems.
