Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0019] In the embodiment of the present invention, there is no need to arrange a large-volume filter capacitor between the power circuit board and the control circuit board, but it is separately arranged on an auxiliary circuit board, and a device storage slot dedicated to accommodate the filter capacitor is opened on the bottom plate , so that the gap between the power circuit board and the control circuit board can be reduced, which is conducive to making the serv...

The invention discloses a servo drive controller which comprises a bottom board, a power circuit board, radiating fins and an auxiliary circuit board. The bottom board comprises a bearing surface and a radiating surface, the power circuit board is arranged on the bearing surface of the bottom board, heat of the power circuit board is dissipated via the bearing surface, and the radiating fins are arranged on the radiating surface in a thermal coupling manner. At least one filter capacitor is arranged on the auxiliary circuit board, the filter capacitors are electrically connected with the power circuit board by the auxiliary circuit board, a device accommodating groove is arranged on the bearing surface of the bottom board, the depth of the device accommodating groove is smaller than or equal to the height of each radiating fin, the auxiliary circuit board is opposite to the device accommodating groove, and the filter capacitors are accommodated in the device accommodating groove. The filter capacitors are independently arranged on the auxiliary circuit board, the device accommodating groove specially used for accommodating the filter capacitors is arranged on the bottom board by utilizing the heights of the radiating fins, and accordingly the servo drive controller can be thinned advantageously.
Description
technical field [0001] The invention relates to the technical field of automatic control, in particular to a servo drive controller. Background technique [0002] The power circuit board of the existing servo drive controller usually installs a plurality of vertical filter capacitors, and the height of the filter capacitors is relatively high. In order to install these filter capacitors, the servo drive controller needs to reserve a large space, so that the servo drive The thickness of the controller is relatively thick, which is not conducive to the thinning of the servo drive controller. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a servo drive controller. Thinning of the servo drive controller can be realized. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a servo drive controller, which includes a base plate, a power circuit bo...
