Encoders used in gearbox and motor applications play a crucial role in motion control systems. These encoders precisely track the rotational movement of the motor or gearbox, providing feedback. This feedback is utilized to determine the speed, position, and direction of the motor. As a result, various applications such as industrial robots, CNC machines, conveyor systems, among others, benefit from stable and accurate motion. Encoders also monitor errors and deviations in the system, thus improving efficiency and reducing maintenance costs. Therefore, they are considered essential components of industrial automation.
