This article mainly introduces "which types of encoders are divided into". In the daily operation, I believe that many people have doubts about which types of encoders are divided into. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the questions of "which types of encoders are divided into?" Next, please follow the editor to study!

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 communicated, transmitted, and stored. The encoder converts angular displacement or linear displacement into electrical signals, the former is called code disk, and the latter is called code ruler.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

An encoder (encoder) is a device that compiles and converts a signal (such as a bit stream) or data into a signal form that can be communicated, transmitted, and stored. The encoder converts angular displacement or linear displacement into electrical signals, the former is called code disk, and the latter is called code ruler.

Encoders can be classified in the following ways.

1. Different classification according to the engraving mode of the code disk.

(1) incremental type: that is, a pulse signal is emitted at the angle of each turning unit (there is also a sine and cosine signal, and then it is subdivided to produce a pulse with a higher frequency). Usually A phase, B phase, Z phase output, A phase, B phase delay 14 cycles of pulse output, according to the delay relationship can be distinguished positive and reverse And 2 or 4 frequency doubling can be carried out by taking the rising and falling edges of A phase and B phase. The Z phase is a single-loop pulse, that is, one pulse per circle.

(2) absolute value type: corresponding to a circle, the angle of each reference emits a unique binary value corresponding to the angle, and multiple positions can be recorded and measured by an external loop device.

2. According to the output type of signal, it can be divided into voltage output, collector open circuit output, push-pull complementary output and long-line drive output.

3. classification in the form of mechanical installation of encoders

(1) Shaft type: shaft type can be divided into clamping flange type, synchronous flange type and servo installation type, etc.

(2) sleeve type: sleeve type can be divided into semi-empty type, all-empty type and large caliber type.

4. According to the working principle of the encoder, it can be divided into photoelectric type, magnetoelectric type and contact brush type.

At this point, the study of "which types of encoders are divided into" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
