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.

C = Standard Capacitor

G = Standard Resistor

(Values of C and G will be determined by the frequency "F" of the generator (GEN) voltage.)

Rectangular Impedance is R + JXL with R read directly from Dial "R" and the XL calculated from

XL = 2 š FL with the L read directly from Dial "L".

Polar Impedance is Z at an angle of X. The angle derived from Tan Φ = R / XL

Z derived from Z = √ R + XL
