[0030] like Figure 1-5 As shown, a novel conductive structure includes a motor and a motor bracket 101. The motor is placed on the motor bracket 101. The motor includes a housing 102, bearing end caps 104, a stator core 109, a conductive wire 105, and a conductive pin 110. There are two sets of bearing end caps 104, which are respectively connected to the two ends of the housing 102. The two sets of bearing end caps 104 are conductive to each other. The stator core 109 is located inside the housing 102. The bearing end caps 104 and the motor bracket 101 are conductive to each other through the conductive wire 105. The bearing end caps 104 and the stator core 109 are conductive to each other through the conductive pin 110.

[0031] Furthermore, the outer casing 102 is provided with a wire bushing 107, which is an arc-shaped plate structure that fits the side wall of the outer casing 102. The wire bushing 107 is provided with a conductive terminal 108, which protrudes from the wire bushing 107 to facilitate connection with the conductive wire 105. One end of the conductive wire 105 is connected to the conductive terminal 108, and the other end is connected to the bearing end cover 104.

[0032] Furthermore, the motor also includes a connecting arm 106, through which the two bearing end caps 104 are connected. The connecting arm 106 is fixed to the bearing end caps 104 by bolts. The connecting arm 106 is provided with a connecting end, and one end of the conductive line 105 is connected to the connecting end.

[0033] A gap is provided between the motor end cover 103 and the bearing end cover 104, and the conductor 105 is located in the gap.

[0034] The stator core 109 is provided with multiple through holes 1091, which are uniformly stitched around the stator core 109. One end of the guide pin 110 abuts against the stator core 109. Both ends of the outer casing 102 are provided with motor end covers 103, and the other end of the guide pin 110 abuts against the motor end cover 103.

[0035] Furthermore, the wire bushing 107 is provided with a connecting part 1071, and the connecting part 1071 is provided with a limiting plate 1072. The limiting plate 1072 is perpendicular to the connecting part 1071, and the connecting part 1071 is perpendicular to the wire bushing 107.

The connecting part 1071 is clamped between the outer shell 102 and the motor end cover 103 for fixation.
