Servo Motor Controller Circuit Schematic The circuit is designed to give control signals to the Servo.IC1 is designed as an Astable multi vibrator which can give pulses for the operation of the Servo.

The simple circuit design in lets you measure all components of a current flowing in a dc servo motor. The rectified output of the circuit uses ground as a reference, so you can measure the output by ...

READ MORE: Get Attuned to Servo-Motor Driver Tuning There are two types of servoamp inputs. Single-ended inputs are shown in the schematic above.

The circuit was successfully tested using a 1-kHz sine wave for the input with an amplitude of 4.5 V, and it produced a 1-V amplitude sine-wave output using a 1-V reference for the set point.
