[0002] As a core component of electric actuators, encoders play a crucial role in stroke position feedback, speed detection and control, and fault diagnosis and protection. As a key feedback element, they provide signal support for the entire actuator control system. The internal mechanical structure of an encoder typically involves gears with periodically arranged light and dark stripes or magnetic poles. As the gears rotate, these stripes or poles generate continuously changing optical or magnetic signals in the sensor, which are ultimately converted into electrical signals received by the electronic circuitry. In this process, the transmission accuracy and meshing condition of the gears determine the encoder's accuracy and lifespan. To ensure product quality, rigorous inspection of the encoder's gear transmission is necessary. However, no such testing equipment is available on the market.
