MIL-DTL-81963 Servocomponents, Precision Instrument, Rotating, Common Requirements And Tests, General Specification ForThis 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.
