Description

Technical Field

[0001] The utility model relates to the technical field of drivers, in particular to a dustproof driver. Background Art

[0002] Servo drives are an important part of modern motion control and are widely used in automation equipment such as industrial robots and CNC machining centers. In particular, servo drives used to control AC permanent magnet synchronous motors have become a research hotspot at home and abroad. Current AC servo drive designs generally use current, speed, and position closed-loop control algorithms based on vector control.

[0003] A servo motor driver with an interface dustproof function disclosed in the existing publication number CN211860799U includes a shell and a base plate, the base plate is arranged inside the shell, the surface of the base plate is connected to the servo body, a cover plate is hinged on one side of the upper end of the shell, a wiring port is arranged on the side wall of the shell, an opening seal is arranged on the outside of the wiring port, at least four shock-absorbing members are arranged between the inner bottom end of the shell and the base plate, an elastic cushion layer is arranged on the outside of the base plate, and the elastic cushion layer is fixedly connected to the inner wall surface of the shell; the wiring port can be sealed by arranging an opening seal on the outside of the wiring port, and two pressure plates can be driven by compression springs to cooperate with connecting wires of different diameters and numbers, and the gap between the pressure plate and the connecting wire is filled by the flexible sealing layer, which plays a dustproof role and avoids problems such as local short circuit caused by dust easily falling into the servo driver interface.

[0004] Although the existing technology plays a dustproof role to a certain extent, it cannot provide further dustproof protection for the control board and the power board inside the driver. Therefore, we propose a dustproof driver. Utility Model Content
