Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy.

[0003] In order to facilitate installation, the brush assembly of a general motor usually adopts a structure such as a slot of a conductive sheet to insert and fix the electrical wiring in the slot structure, and other methods for reinforcing the connection are limited. Although the installation efficiency is high, the structures are prone to loosening after long-term use, resulting in circuit power-on failure. Therefore, a brush assembly of a motor is proposed to address the above problems. Summary of the invention

[0004] The object of the present invention is to provide a brush assembly for a motor in order to solve the above-mentioned problem.

[0006] Preferably, a carbon brush is installed on the other end of the brush supporting copper sheet.

[0007] Preferably, two copper coils are provided, and the two copper coils are respectively installed at two corresponding copper coil installation positions.

[0008] Preferably, a wire arrangement groove and an end fixing section are distributed at the copper coil installation position, and the wire arrangement groove and the end fixing section are respectively clamped and fixed to corresponding positions of the second conductive profile.

[0009] Preferably, the conductive profile installation portion is symmetrically provided with two T-shaped slots, and the T-shaped slots are clamped together with corresponding clamping pieces.

[0010] Preferably, the capacitor element is installed in a corresponding capacitor installation groove, and the two capacitor installation grooves are symmetrically arranged at corresponding positions on the brush fixing ring.

[0011] Compared with the prior art, the difference of the present invention lies in that the connection between the brush fixing ring, the conductive part and the electrical wiring adopts a combination of a clamping structure, soldering and an insertion structure, which greatly enhances the firmness of the electrical connection and solves the problem of the electrical wiring part being inserted into the slot structure and then loosened after being pressed, thereby reducing the failure rate of the circuit power-on and facilitating the overall installation.
