一种电动舵机设计中直流电机选用方法

摘要

In the designing process of aviation airborne equipment dynamoelectric rudder machine ( servo actua-tor) , this paper elaborated a new method to select DC motor, namely, a mechanical characteristics target selection method. The main steps to select DC motor by using mechanical characteristic target selection method were presented. Using this method can make selected motors more reasonable, more reliable and safe, more economical under the premise of satisfying product performance requirements. This selection method can be applied to the servo machine transmission system with DC motor as motive source, such as automatic control equipment, electric power transmission and drag, machatronics products.%介绍了在航空机载设备电动舵机(伺服作动器)设计过程中，选用直流电动机的一种新方法。通过与一般的选用直流电动机使用方法的比较，提出了一种选择直流电动机的新方法，即机械特性目标选择法。给出了利用机械特性目标选择法选择直流电动机的主要步骤。使用此方法能使所选电动机在满足产品性能指标要求的前提下，更加优化、科学，合理可靠，安全节能。该选择直流电动机的方法均适用于直流电机作为动力源的伺服机械传动系统中，如自动控制装置、电力传动与拖动、机电一体化产品等。
