摘要
分析了适合弱磁运行的永磁同步电动机的结构特点,从本体和控制两个方面介绍了永磁同步电动机的弱磁方法,指出各种方法的优缺点。最后综述了国内外弱磁扩速研究的发展现状,重点介绍了复合转子电机和4种通过改变磁通路径弱磁的新型电机。
The structural characteristic of permanent magnet synchronous motor that adapted for flux weakening operation was analyzed. The flux - weakening method was introduced from the aspects of the motor design and control, the advantages and disadvantages of these flux - weakening methods were pointed out. At last the developing present state at home and aboard was summarized,the compound rotor and 4 novel permanent magnet motors that changed the flux path to realize the flux weakening were highlighted.
