A Displacement or Velocity Servo Amplifier
W. Roth · 1946
Abstract : A servo amplifier designed for use with a Diehl FPE-49, two-phase, 60-cps induction motor is described. It can be used either as a displacement or a velocity servo since input circuits adaptable to either usage are provided. The unit is designed for a maximum usable power of 50 watts with high stability and accuracy. Emphasis has been placed on ease of adjustment and maintenance.
