There is currently no unified standard for the expression of "split modular encoder" in Chinese translation. In terms of English expression, different manufacturers also have different explanations for it. For example, Precizika uses "Tailor Made Encoder Kits"; Renishaw uses "Encoder Module"; HEIDENHAIN has not yet systematically promoted the split type and uses "Encoder Module" in terms of expression; other brands such as LIKA also use "Encoder Kits". Based on this, and our understanding of the product, in Chinese, we currently use "modular encoders without built-in bearings", which can also be referred to as "modular encoders" Split modular encoder ". In subsequent articles, we will mainly use" Split modular encoder "as the expression for this type of product.

 

 

 

The split modular encoder consists of two independent components, namely a grating code, and a reading head module. Compared with the enclosed integrated encoder, this form of encoder has the following characteristics:

Due to its flexible installation method, customizable according to practical applications, compact structure, and high repeatability, the split modular encoder can be widely used in the following fields:

 

 

The split modular encoder can be used to control the electric spindle of machine tools. Due to its simple mechanical structure and the ability to achieve larger installation dimensions at a lower cost, it is often used in the design and production of high-speed and high-precision electric spindle products.

The split modular encoder can be used for controlling the robot's motion axis, such as the robot's joint axis, servo motor, etc., to improve the positioning accuracy and motion speed of the robot. And it can provide powerful motion feedback data support for the robotic arm to execute more complex motion and control algorithms through high-precision servo positioning feedback data, achieving more functions.

 

Including DD motors, is also one of its important application points.

The split angle encoder has the characteristics of a simple mechanical structure, no mechanical transmission components between the installation shaft, and no need for lubricants; It is very suitable for working conditions with extremely high requirements for cleanliness in the working environment (due to the absence of bearings and other components, the product itself will not produce wear debris), or must work in a high vacuum environment (ensuring no lubricants), and is often used in medical devices, aerospace equipment, and electronic processing equipment.

With the combination of artificial intelligence and mechanical design in the future, the advantages of split encoders will also become increasingly prominent.
