Hybrid rotary encoder！

Hybrid rotary encoder
Hybrid encoder single-turn or multi-turn type, which itself offers the advantage of incremental and absolute encoder technology. This provides users with the potential to replace two encoders, can reduce the cost and space. This type of encoder provides a pulse or sine / cosine waveform, ideal for blade pitch control system because it provides real-time feedback of the motor speed up to 6000rpm need, but also be able to save the absolute single-turn when the system is powered down multi-turn position data. Currently, there are a lot of motor drives have increased the standard input for receiving the sine / cosine wave feedback. Sometimes, customers can obtain a higher motor efficiency.

Overview
Not all rotary encoders are equally important, today's incremental, absolute and mixed encoders are used in the design of optical and magnetic technology is constantly improved to increase the resolution, temperature range and durability. Optical encoder Opto-ASIC design utilizing new technologies such as improved, second or third-generation design provides higher resolution capability, faster operating speed, and improved operating temperature range. Furthermore, Opto-ASIC by an electric field adjustable resolution, output drive type (TTL or HTL) and the width of the marker, enabling the user to program the encoder.


Metal Optical discs is another important improved encoder component that enables the encoder to operate in harsh environments and provide a higher resolution. In the past, incremental and absolute encoder need to use an optical disk glass to achieve higher resolution, but it reduces the resistance to shock and vibration. Metal Emerging Optical disc resolutions up to six times without the use of electron multiplier, and has better shock and vibration performance.


Many new encoder design is its reduced size. However, if the design and construction can not meet high quality standards, all these technical improvements are of little value and volume reduction. For example, the quality of the bearing, assembly methods and the distance between the bearing will greatly affect the life of the encoder.
