Since the outer surface of the second panel 113 is covered with the sensor array member 15, the second vent 164 is disposed on the first panel 112, the second vent 164 penetrates the first panel 112 along the first direction X, and the second vent 164 may be disposed only on one side of the interface 18 in the second direction Y, or may be disposed on both sides of the interface 18. The number of second vents 164 on one or both sides of the interface 18 may be one or more. When the circuit board 17 works, heat generated by the circuit board can be emitted to the outside of the stator module 1 through the interface 18 and the second air vent 164.

As shown in fig. 9, in a specific structure, the middle portion of the first panel 112 along the third direction Z has an interface 18, two ends of the interface 18 along the second direction Y have second ventilation openings 164, the circuit board 17 is located in the accommodating space and has a gap with the bottom plate 114, two ends of the circuit board 17 along the second direction Y have fans 161, two ends of the fans 161 along the second direction Y are provided with heat sinks 162, and the heat sinks 162 are fixed to the first ventilation openings 163.

In a specific heat dissipation mode, the fans 161 at both ends can be operated in the forward direction or the reverse direction at the same time, and wind enters from the first ventilation opening 163 at one side, passes through the radiator 162 and the fan 161 at one side, blows toward the circuit board 17 and the armature winding 14 to dissipate heat, passes through the fan 161 and the radiator 162 at the other side, and blows out from the first ventilation opening 163 at the other side.

In another specific heat dissipation mode, the fans 161 at both ends may rotate one forward and the other backward. The first panel 112 has an interface 18 at a middle portion thereof, and second ventilation openings 164 are provided at both ends of the interface 18 in the second direction Y. When the fans 161 at both ends are rotated one forward and the other reverse, wind can be blown in from the interface 18 and the second ventilation opening 164 to cool the armature winding 14 and the circuit board 17, then pass through the fans 161 and the heat sinks 162 at both ends of the circuit board 17, and finally be blown out from the first ventilation opening 163. On the other hand, the wind may be blown through the first ventilation openings 163 at both ends of the housing space, through the heat sinks 162 and the fans 161 at both ends, toward the circuit board 17 and the armature winding 14, and finally through the interface 18 and the second ventilation openings 164.

As shown in fig. 10, in still another specific structure, the bottom plate 114 is provided with a third vent 165 along the third direction Z, and when the circuit board 17 is operated, heat generated can be dissipated from the first vent 163, the second vent 164, and the third vent 165.

As shown in fig. 11, in another specific structure, a fan 161 is disposed on a side of the bottom plate 114 facing away from the armature winding 14, that is, a fan 161 is disposed below the bottom plate 114 along the third direction Z, and when the circuit board 17 is operated, the fan 161 disposed below the bottom plate 114 may also radiate heat from the first ventilation opening 163 and the second ventilation opening 164 in a manner of rotating forward or backward.

When the motor transmission system 100 starts to operate, the sensing part 25 on the mover body 21 receives a signal from the sensor array part 15 on the second panel 113, periodically excites the armature winding 14, and interacts with the magnet 24 to push the mover body 21 to move. Both the armature winding 14 and the circuit board 17 generate heat, and thus the circuit board 17 controls the fan 161 to radiate heat by rotating in the forward or reverse direction.

As shown in fig. 12, in some embodiments, the motor transmission system 100 further includes a cover plate 19, where the cover plate 19 is disposed on a side of the first panel 112 facing away from the second panel 113, and the cover plate 19 and the first panel 112 together form a wire collecting slot, where the wire collecting slot can collect wires, so as to prevent the wires from interfering with other components on the motor transmission system 100 during the movement of the mover body 21; alternatively, in some embodiments, the cover plate 19 is disposed on a side of the second panel 113 facing away from the first panel 112, and the cover plate 19 and the second panel 113 together form a slot; alternatively, the cover plate 19 is disposed on both the side of the first panel 112 facing away from the second panel 113 and the side of the second panel 113 facing away from the first panel 112, so that both sides of the stator body 11 can be used for bundling cables.

The cover plate 19 is provided with a fourth air port 191, and the fourth air port 191 and the second air port 164 are arranged opposite to each other, so that heat in the accommodating space can be dissipated more quickly, and a better heat dissipation effect can be achieved.
