Abstract

The invention discloses a controller for a brushless DC motor. The controller for the brushless DC motor comprises a bottom plate, a silica gel layer, a PCB and a shell; a lead wire terminal installation component is arranged at the top end of the PCB, and a plurality of MOS pipe installation components are arranged both on the left side and the right side of the top end of the PCB; the bottom end of the shell is open and an accommodating cavity is formed inside the shell, and a plurality of terminal mounting holes are formed in the top of the shell; the PCB is arranged in the accommodating cavity, and lead wire terminals in the lead wire terminal installation component are penetrated in the terminal mounting holes, and the bottom plate is pressed tightly with the bottom end of the PCB through the silica gel layer. The controller for the brushless DC motor provided by the invention has simple structure and further has the advantages of simple manufacturing process and low manufacturing cost.

Description

technical field [0001] The invention relates to the field of brushless direct current motors, in particular to a controller for brushless direct current motors. Background technique [0002] At present, in the field of brushless DC motor controllers, the MOS tube is mainly installed by means of installation and pressing, specifically: use screws to lock the insulating particles on the aluminum strip or the shell, and then press the MOS tube on the On the aluminum bar or shell; in the brushless DC motor controller, the number of MOS tubes to be installed is large, and the number of screws and insulating particles required is correspondingly increased, which not only increases the manufacturing cost of the brushless DC motor controller, Moreover, the manufacturing process of the brushless DC motor controller becomes more cumbersome. In addition, when the spring steel sheet is used to press the MOS tube, the pressure of the spring steel sheet is relatively high, and the positi...
