Overview

The Rotary Servo Base Unit is a geared servo-mechanism system. The plant consists of a DC motor in a solid aluminum frame. This DC motor drives the smaller pinion gear through an internal gear box. The pinion gear is fixed to a larger middle gear that rotates on the load shaft. The position of the load shaft can be measured using a high resolution optical encoder. The Rotary Servo Base Unit is also equipped with an optical encoder and a potentiometer to measure the output shaft position, and a tachometer to measure the speed of the motor.

  • High-quality DC servo motor and gearbox
  • High-resolution optical encoders to sense position
  • Continuous turn potentiometer to sense position
  • Tachometer to sense motor speed
  • Variable loads and gear ratios
  • Optional slip ring for continuous measurement from instrumented modules
  • Ten add-on modules available
