What are the advantages of rotary encoders
With the continuous development of industrial control, rotary encoders have new requirements and are used more and more widely. Rotary encoders have the characteristics of small size, light weight, multiple varieties, complete functions, high frequency response, high resolution, small torque, low energy consumption, stable performance, reliable and long service life, and are highly favored by designers.
The rotary encoder is convenient and safe to install on site, and has a long life: a fist-sized rotary encoder can measure distances from a few μ to several hundreds of meters, with n stations. As long as the problem of safe installation of a rotary encoder is solved, It can avoid the trouble of mechanical installation of many proximity switches and photoelectric switches in the field, which are easy to be damaged, high temperature, moisture and other problems. Because it is a photoelectric code disc, there is no mechanical loss, as long as the installation position is accurate, its service life is often very long.
The advantages of rotary encoders are summarized as follows:
1. Informatization, in addition to positioning, the control room can also know its specific location;
2. Flexible, positioning can be adjusted flexibly in the control room. Convenience, safety and longevity of on-site installation: A rotary encoder with the size of a fist can measure intervals from a few μ to several hundreds of meters, n stations, and only need to process one rotary encoder (Changchun encoder) The safety device question can prevent many close switches and photoelectric switches from troublesome mechanical installations on site, simply being damaged and being confused by high temperature and moisture. Because of the photoelectric code wheel, there is no mechanical loss, only the device orientation is accurate, and its service life is often very long.
3. Multifunctionality, in addition to positioning, it can also transmit the current position remotely, and convert the movement speed. It is especially important for the use of frequency converters, stepping motors, etc.
4. Economicalization. Regarding multiple control stations, only the cost of a rotary encoder is required, and the more important equipment, protection, and loss cost are reduced, and the service life is increased, and its economicalization is gradually highlighted.
Rotary encoders are divided into two types: incremental encoders and absolute encoders. Both have their own advantages and disadvantages. Incremental encoders are more common, and they are used in most occasions. From the price point of view, in general, absolute encoders are much more expensive, and absolute encoders have a measuring range, so they are generally used on machine tools with special needs.
