Talking about the classification and principle of encoder How do the elevators that are often used in life accurately send people to the designated floors? How does the machine tool accurately cut materials? How does the servo motor ensure the accuracy of the rotation position? All this is due to an artifact— —Encoder, but what is an encoder? How does he accurately measure the position of the motor? Let’s talk about the encoder today.

The encoder An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a signal form that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code wheel and the latter is called a code ruler.

Technical characteristics of the encoder industry With the addition of industrial control needs, the application of encoders has become more prominent and outstanding. European and American brands occupy the high-end market with more than 30% market share. Chinese brands occupy the mid-range market with 24.9% market share. The following is the encoder industry technology Characteristic analysis.

Servo encoder differential signal 5v24v12v to pulse signal transmitter Main features: >> Encoder differential signal is directly input and converted into pulse signal >> Support A, B and Z three-phase differential simultaneous conversion >> 4 inputs, 4 outputs, output pulse amplitude optional

The structure, principle and application of incremental photoelectric encoder Summary of content: The photoelectric encoder is a high-precision digital detection device. There is a knob that can be rotated left and right at the same time. It is widely used for menu selection and adjustment of vehicle electronic equipment. Mainly taking the Japan Alps EC11J miniature photoelectric encoder as an example, the structure and principle of the incremental photoelectric encoder are analyzed, and its application in the volume adjustment of car audio is explained.

Application of photoelectric encoder in motor control system Overview: Motor position detection is very important in motor control, especially in applications where the motor's motion state needs to be controlled based on the precise rotor position, such as a position servo system. The position detection in the motor control system usually includes: micro-motor solving components, photoelectric components, magnetic sensitive components, electromagnetic induction components, etc.
