Analysis of the function characteristics of hollow encoder

The hollow encoder is a very flexible rotary encoder. Its characteristics are mainly compact and convenient to adjust. Generally, the position can be flexibly adjusted by the spring leaf, and the hollow encoder can pass the A phase pulse signal and the B phase output time , Then the value of the pulse signal can be used to grasp the direction of rotation. Currently, hollow encoders are generally suitable for use in a variety of applications. Just give a brief talk about the analysis of the functional characteristics of the hollow encoder below.

Analysis of the function characteristics of hollow encoder

Characteristic analysis one

The hollow encoder does not need to refer to the drive after the power supply is started or the internal and external power supply fails, and the current accurate position can be obtained after the power supply is normal. Under the interference of various harsh environments, the original position test data of the hollow encoder can still maintain stable operation, and will not be easily affected by interference.

Characteristic analysis two

The hollow encoder can provide an incremental pulse code value for each axis position, especially in position control, the incremental encoder does not need to count, and can achieve direct internal high-speed reading and external output. Secondly, the subsequent calculation task of the hollow encoder in the receiving device controller can reduce the cost of other additional input components. For example, an industrial robot with a hollow encoder working in parallel on multiple axes can realize high-speed multi-axis parallel and synchronous work. And various control fields that require multi-axis synchronization.

Characteristic analysis three

Fast and reliable digital data transmission is currently one of the core elements of hollow encoders. Due to the high-bit resolution characteristics, generally hollow encoders directly output digital signals without internal and external counting, so they are no longer read Impulse and cumulative effects. It can respond at high speed. For some high-efficiency equipment, the hollow encoder can also achieve high-bit resolution.

Characteristic analysis four

There is also a hollow encoder which is a very flexible encoder. Its characteristics are mainly compact and convenient to adjust; generally, the position can be flexibly adjusted by the spring leaf, and the hollow encoder can pass the A phase pulse signal and the B phase output Time, then the value of the pulse signal to grasp the direction of rotation. Currently, hollow encoders are generally suitable for use in a variety of applications.

Characteristic analysis five

The clamping method and spring sheet structure of the hollow shaft encoder make it very convenient to adjust the position and absorb the vibration and impact of the load. Moreover, the hollow encoder will output according to the rotation displacement of the shaft during operation, and the joint can be combined with the shaft to directly detect the rotation displacement. Normally, there is no need to return to the origin at startup. Under normal circumstances, the rotation angle can be output in parallel as an absolute value.
