This simple DC servo motor circuit design that can be used in various electronic projects. As you can see in the circuit schematic this Dc servo motor driver schematic circuit use just one integrated circuit and other few external electronic components. With bidirectional dc servo motors, the PHASE terminal can be used for mechanical direction c
ontrol. Similar to when braking the motor dynamically, abrupt changes in the direction of a rotating motor produce a current generated by the back EMF. The current generated will depend on the mode of operation.
