What is the influence of magnetic ring multipole and multipole on encoder, 20.22.24.26?

Magnetic ring encoder can be used on the spindle of machine tool.

1. Magnetic ring encoder can be used on machine tool spindle. Many manufacturers choose magnetic ring encoders instead of traditional photoelectric encoders. Magnetic ring encoder has the characteristics of anti-vibration, anti-pollution and high reliability.

2. The encoder on the spindle of the machine tool can be directly installed on the spindle, instead of needing a special position and coupling connection like others. The common encoders are generally glass encoders, which are afraid of vibration and fragile, while magnetic ring encoders work by using magnetoelectric sensing technology, so they are strong in anti-interference, durable and convenient to install. The disadvantage of magnetic ring encoder is that the resolution is not very high.

3. 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 code wheel, and the latter is called code wheel. According to the reading mode, encoders can be divided into contact type and non-contact type; According to the working principle, encoders can be divided into incremental and absolute types. Incremental encoder converts displacement into periodic electrical signal, and then converts this electrical signal into counting pulses, and the number of pulses indicates displacement. Each position of absolute encoder corresponds to a certain digital code, so its indication value is only related to the starting and ending positions of measurement, and has nothing to do with the intermediate process of measurement.
