When welding the conductive connecting rod and the PCBA board, the solder may fall along the conductive connecting rod, and the dropped tin is not protected or collected, which may cause the pins on the PCBA to touch the dropped solder by mistake, resulting in PCBA board short circuit
[0003] In addition, the armature assembly connects the wiring harness winding and the PCBA board of the controller assembly through the conductive connecting rod on the conductive bracket, and the insulating end cover of the armature assembly is embedded with a metal guard hook, which has a convenient conductive The connecting rod hook connected by the connecting rod and a wire harness hook that is convenient for the wire harness to pass through. However, when the output power of the brushless motor increases, for example, to 600W, the armature winding
