Description

Distributed annular servo driver Technical Field The application relates to the field of servo drivers, in particular to a distributed annular servo driver. Background The distributed servo drivers are distributed and deployed at different positions through a distributed architecture, and each driver is independently responsible for controlling one motor shaft. The drivers realize data interaction and cooperative work through a high-speed communication network. The mode greatly reduces the operation pressure of a single controller and improves the control response speed. Because each driver is close to the controlled motor, the distance of signal transmission is reduced, and the signal attenuation and interference risks are reduced. However, with the rapid development of industrial automation production, conventional distributed servo drives cannot meet all application scenarios. Especially for the situations of narrow application scenes and limited installation space, the servo driver cannot be conveniently installed on the driving equipment, and an additional installation structure can be added to enable the servo driver to be installed near the controlled motor. This results in a waste of space and also increases the overall volume of the device.
