Abstract
Description
Technical Field
[0001] This utility model belongs to the field of encoder technology, and in particular relates to a split encoder. Background Technology
[0002] An encoder is a sensing device whose core function is to convert physical quantities into processable electrical or digital signals. It is primarily used for real-time feedback in communication, transmission, storage, or motion control systems. Existing encoders typically consist of a grating disk, light-emitting diodes (LEDs), photosensitive elements, a circuit board, a code disk, and a housing. These encoders are usually integrated, with components like the grating disk housed within the housing. Due to this integrated design, maintenance often requires the entire encoder to be replaced if any part fails, resulting in high maintenance costs. Furthermore, the electronic components are located in the same space as the encoder shaft, making them susceptible to damage from heat generated by the shaft and bearings. Summary of the Invention
