What is a motor encoder?

Motor encoder is a kind of equipment that can convert motor motion into digital signal. It is mainly composed of encoder gear, encoder signal conversion circuit, pulse counter and signal interface. Motor encoders are often used in robotics, industrial automation, medical equipment, automobile industry and other fields. Its main function is to control the rotation angle, angular velocity and position of the motor.

The encoder of motor usually consists of two parts-mechanical part and electronic part. The mechanical part includes shell, gear, shaft and bracket. Mainly to establish a mechanical interface to connect the motor and mechanical equipment. The electronic part includes signal converter, pulse counter, digital signal interface and so on. It converts mechanical rotation into electronic pulse signal through signal converter, and then converts pulse information into digital signal.

The working principle of motor encoder is based on the principle of magnetic induction. It mainly detects the motion state of the wheel through the sensor close to the gear. These sensors can sense the changes of the external magnetic field, then convert these changes into electrical signals, and then transmit the information to the controller or computer through signal lines.

Although the motor encoder is relatively simple, it plays an important role in controlling robots, mechanical arms and medical equipment. Encoder can quickly achieve multiple goals, improve production efficiency, and better control the rotation and accuracy of the machine.

In a word, motor encoder is an indispensable equipment in the industrial field at present, and its appearance has brought a lot of convenience to various industries, and also promoted the development of intelligent manufacturing and Industry 4.0.
