摘　　要：为研制用于驱动大流量伺服比例阀先导级的高响应电机械转换器,提出永磁体励磁的动磁式电机械转换器结构方案,完成了转换器的结构设计和仿真计算。利用FEM软件对磁场分布和输出特性进行了分析。结果表明,动磁式电机械转换器具有输出力值大、波动性小、工艺性强的特点,可以满足大流量伺服比例阀先导级驱动的要求。In order to develop a fast response electro-mechanical transformer used to drive the pilot stage of large flow rate servo proportional valve, a moving magnet electro- mechanical transformer was proposed to meet the demand. The structural design was made. The test results show that it has the advantages of simple structure and process, good stabliility and linearity, high sensitivity, and can meet the pilot driving requirement of large flow rate servo proportional valve.
