摘　　要：磁流体具有较大的磁导率,而且在外加磁场作用下具有较大的磁化强度,利用磁流体的这些特点,通过在伺服阀力矩马达的工作气隙中添加磁流体,从而达到改善力矩马达性能的目的。本文分析了采用磁流体的射流管伺服阀中力矩马达的结构及工作原理,对力矩马达的静态特性进行了试验研究,介绍了试验原理,得到了相应的试验结果。Magnetic fluid has bigger magnetic inductivity, and has bigger magnetization intensity when exposed to a magnetic field. Using these characteristic, we can improve the performance of torque motor by filling the working clearances of torque motor with magnetic fluid. This article provide the structure and working principle of torque motor with magnetic fluid, and make the experiments study of torque motor static characteristic, and introduce the principle of experiments, and educed experiments result.
