What is a Encoder?

An encoder is a sensor that converts rotational or linear motion into electrical signals. It is primarily used for measuring the position, speed, and angle of motors and machines. An encoder typically consists of a disk or rotor attached to a rotating shaft, with patterns (such as slits or magnetic marks) on the surface. These patterns are used to detect rotation and position, converting the information into digital signals which are sent to machines or control systems. There are two main types of encoders: incremental encoders, which measure changes in motion, and absolute encoders, which measure the absolute position directly. Encoders are widely used in applications that require precise movement, such as robotics, CNC machines, and conveyor systems.

Application of Encoder

✅ Robot Position Control
Encoders are used to precisely control the rotation angles of robot arms and joints. By using absolute encoders, the exact position of each part is measured, enabling the robot to perform highly accurate movements.
✅ CNC Machine Positioning
In CNC (Computer Numerical Control) machines, encoders are used to detect the precise position of tools and tables. This ensures high processing accuracy, improving the quality of the manufactured products.
✅ Motor Control Systems
Encoders measure the rotation speed and angle of motors and are used to control motor speed and position. For example, in robotic and electric vehicle drive systems, encoders monitor rotational motion in real-time.
✅ Conveyor System Position Detection
Encoders are used to measure the position of conveyor belts. By accurately tracking belt speed and position, production line efficiency can be improved, and product flow can be better controlled.
