Motion Control is a sub-field of automation where the position or velocity of machines are controlled by using devices like pumps, linear actuators or electric motors.
Motion Control is an important part of robotics and CNC machine tools – however, these applications are typically more complex compared to those of specialised machines. In many cases mechanical components like gears, shafts, bearings, ball screws, belts and pulleys are used to transform the motion of an actuator into the desired motion needed for a specific application.
To control the motion of an application, feedback sensors and switches are used to close the position or velocity control loops to the motion controller.
