摘　　要：介绍了一种新型的无磁仿真转台用凸轮转子连续回转电液伺服马达的工作原理及特点.通过对其叶片的系统受力分析,得出马达波动力矩产生的机理.利用Matlab软件对马达低速运行时,叶片产生的干扰力矩进行了仿真,并对不同减压阀出口油压及不同叶片厚度下的干扰力矩进行对比,得出相关参数对该类型马达力矩波动产生的影响.为解决该类液压马达存在的低速速率波动现象提供了一定的理论依据.A new kind of continuous revolving electro-hydraulic servo cam rotor motor on the non-magnetic simulation turntable was introduced with its operating principle and features.The mechanism of the motor＇s torque fluctuation was found based on the systematical force analysis of motor＇s vanes.The simulation of disturbing torque produced by the vane was emulated by using the matlab software when the servomotor is working under the low-speed.From the comparisons of disturbing torque under different oil pressure on the reducing valve or different vane thickness,the related parameters＇ effect on the torque fluctuation of this kind servomotor was revealed.The work in this paper presents some theory basis to resolve the phenomenon of velocity fluctuation with low-speed of the servomotor.
