The guide posts 42 pass through the circuit board 2 and are positioned with the motor 1 to ensure accurate installation among the circuit board 2, the metal cover 4 and the motor 1. The design of the guide posts 42 also improves the stability and impact resistance of the structure; a breathable plug is arranged on the metal cover 4, and a downwardly extending heat dissipation boss 43 is arranged on the inner side of the metal cover 4 to increase the heat dissipation area and improve the heat dissipation performance.

[0023] In this embodiment, if Figure 6 As shown, the outer wall or the inner wall of the heat dissipation boss 43 is provided with a plurality of heat dissipation ribs 41, which increases the heat dissipation area, enhances the heat dissipation performance of the motor controller, and effectively prevents damage to the motor controller caused by overheating.
