[0002] During the assembly of a brushed motor, carbon brushes need to be installed. The springs on the carbon brushes make installation inconvenient. Workers need to press the carbon brush into the brush slot while using a tool to hold it down with their other hand before inserting the connector. When inserting the connector, workers need to slightly loosen the pressing tool to facilitate insertion. If the loosening force is too great, the carbon brush can easily pop out of the slot. During installation, the springs on the carbon brushes are prone to twisting or bending, requiring workers to constantly adjust the pressing position. This also presents inconvenience for customers who wish to replace the carbon brushes themselves. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention discloses a carbon brush mounting device for motor assembly. The present invention places the carbon brush through a carbon brush placement mechanism and limits the position of the carbon brush.
