在雷达、指挥仪、自动控制或遥控设备与仪表(如:差热仪、气象记录仪等)中,都用到随动系统。随动系统的跟踪能力,直接影响到这类设备与仪器的性能。为了使随动系统能及时地跟踪主控设备,往往要在伺服机构中增加齿轮减速机构,这不仅提高了成本、增加了系统的体积与重量,增加了能源消耗,而且给安装与维护工作带来了一定的麻烦。为此,我们采用了低压驱动伺服系统,该系统取消了齿轮减速机构,因而克服了该机构的上述缺点,并且提高了跟踪精度其精度优于0.2％。下面,简单地介绍一下低压驱动随动系统及其有关技术问题。
In the radar, conductor, automatic control or remote control devices and meters (such as: differential thermal analyzer, weather recorder, etc.), are used servo system. Follow-up system, tracking capabilities, directly affect the performance of such equipment and instruments. In order for the servo system to track the master device in time, it is often necessary to add a gear reduction mechanism to the servo mechanism, which not only increases the cost, increases the size and weight of the system, increases the energy consumption, and also provides the installation and maintenance work band Some trouble came. To this end, we have adopted a low-pressure drive servo system that eliminates the gear reduction mechanism and thus overcomes the above disadvantages of the mechanism and improves the tracking accuracy with accuracy better than 0.2%. Below, a brief introduction of low-voltage drive servo system and its related technical problems.
