YCM型凸轮式径向活塞液压伺服马达,是用活塞配油的马达。它的工作原理和主要特点,可参看《华东液压通讯》1978年第三期“YCM—27型高响应低速液压伺服马达”一文,这里不再赘述。这种马达动特性好,调速范围宽,低速性能也好,与电液伺服阀配合,特别适宜在高性能的电液伺服系统中作执行元件用,现已成功地使用在三自由度飞行模拟转台伺服系统中,其调速比达40万以上。对这种伺服马达的性能进行测试,与一般的动力马达要求不同,主要应着重于动特性和低速性能的测试。YCM—27A液压伺服马达由于动特性特別好,甚至超过伺服阀的动特性,而马达的启动转速又很低,一般的测速电
YCM cam radial piston hydraulic servo motor, the piston is equipped with a motor. Its working principle and main features can be found in the “East China Hydraulic Communication” 1978 third “YCM-27 high-response low-speed hydraulic servo motor,” a article, not repeat them here. This kind of motor has good dynamic characteristics, wide speed range, low speed performance, and electro-hydraulic servo valve, especially suitable for high-performance electro-hydraulic servo system for the implementation of components, has been successfully used in three degrees of freedom flight Analog turntable servo system, its speed than 40 million. The performance of this servo motor to be tested, with the general requirements of the power motor is different, the main focus should be on dynamic characteristics and low-speed performance test. YCM-27A hydraulic servo motor because of the dynamic characteristics are particularly good, or even exceed the dynamic characteristics of the servo valve, and the motor starting speed is very low, the general tachometer
