摘要
本文基于永磁同步电机的弱磁原理,分析了现行控制策略方式进行弱磁的不足之处。文章从改进电机本体结构着手,阐述了弱磁型永磁电机的工作原理,通过设计特殊的转子结构或者增加相应的调节装置,达到磁场调节的目的。本文综述了五种类型弱磁型永磁电机国内外研究现状,为永磁同步电机特殊场合弱磁应用提供思路。
This paper analyzed the inadequacies of flux-weakening by way of existing control strategies based on the flux-weakening principle of permanent magnet synchronous motors. From the motor body structure, the paper explained the works of flux-weakening permanent magnet synchronous motor, and adjusted magnet- ic field through designing special rotor structures or adding to some mediation devices. The paper proposed the research status of five types of flux-weakening permanent magnet synchronous motor and provided ideas for some special flux-weakening application.
