Motion Control

Motion control is an application field of using various technologies to achieve precise motion control in a wide range of applications. Common types of motion control include servos, DC and AC motors, stepper motors, and motion controllers. Motion control can be used in robotics, automated manufacturing and other industrial applications.Servos are used in robotic and other precision motion control applications. A servo motor consists of an electric motor connected to a positioning controller. The positioning controller consists of a sensor that reads the current position of the motor and a set of switches or a computer program that tells the motor what position to move to. The motor is then powered by electricity and it moves according to the instructions received. DC and AC motors are used in a variety of applications where speed and reliability is required. They are powered by direct current (DC) or alternating current (AC) and can be open-loop or closed-loop, depending on the application. Stepper motors are commonly used in motion control applications where precise positions and speeds are required. They consist of a rotating shaft connected to a set of coils that generate a pulsed magnetic field as the windings are energized. The coils interact with the magnetic field to move the motor one step at a time.Motion controllers are devices that are used to monitor and control a system. They measure the speed and position of the motion and provide feedback in order to keep the motion within its desired range. They can be used to control servos, DC and AC motors, and stepper motors.
