本规范涵盖了模拟、数字和模拟/数字精密仪器旋转伺服组件（同步器、电气分解器、电气、线性分解器、转换器、轴角编码器、伺服电机、转速表发电机、伺服电机转速表发电机、步进电机和齿轮头）的通用要求和测试。本规范将与适用的通用规范一起使用，通用规范涵盖特定类别的伺服组件（例如同步器），以及引用MIL-DTL-81963作为直接参考的文件和规范表，详细说明了单个伺服组件的具体要求。

This specification covers common requirements and tests for analog, digital and analog/digital precision instrument rotating servocomponents (synchros, electrical resolvers, electrical, linear resolvers, transolvers, shaft angle encoders, servomotors, tachometer-generators, servomotor-tachometer generators, stepping motors, and gear heads). This specification will be used with the applicable general specification, which covers a particular class of servocomponents (for example, synchros), together with the documents and the specification sheet that cite MIL-DTL-81963 as a direct reference detailing the specific requirement for the individual servocomponent.
