液压传动 马达特性的测定 第3部分:在恒流量和恒转矩下

[中文适用范围]： 描述了在恒流恒扭矩条件下确定正排量旋转流体动力马达低速特性的方法。 该方法涉及低速测试，这可能产生对电机的稳定连续扭矩输出具有显着影响的频率，并影响电机所连接的系统。 测量精度分为A、B、C三级，解释见附录A。 [外文原描述]： Describes a method of determining the low-speed characteristics of positive-displacement rotary fluid power motors under constand flow and constant torque conditions. The method involves testing at slow speeds, which may generate frequencies having a significant influence upon the steady continuous torque output of the motor and affect the system to which the motor would be connected. The accuracy of measurement is divided into three classes, A, B and C, which are explained in annex A.
