Abstract: A design method of permanent magnet servo motor adapted to high temperature and high power density was introduced. Through the analysis of domestic and foreign technology development status, combined with the special application of high temperature environment, the paper analyzes the technical difficulties of permanent magnet AC servo drive motor in adapting to high temperature and high power density. By improving the electromagnetic and thermal joint design method of permanent magnet AC servo motor,the product work efficiency,output power density and high temperature adaptability were improved.

Key words: high-temperature, high-power density, permanent magnet servo motor, electromagnetic and thermal coupling
