[0034] Optionally, the first stator base 1 can be arranged to extend along the conveying direction. The first stator base 1 can surround a square structure. The second stator base 2 can be located within the square structure surrounded by the first stator base 1. The top of the second stator base 2 can extend out of the square structure, so that the top end of the second stator base 2 is higher than the top end of the first stator base 1.

[0035] The stator body 3 can be fixed to the top end of the second stator base 2. The stator body 3 can also be arranged to extend along the conveying direction. The stator body 3 can be located above the first stator base 1, so that a gap cavity can be formed between the stator body 3 and the first stator base 1. The stator body 3 can be provided with the armature winding 4. The armature winding 4 can be arranged to extend along the extension direction of the stator body 3. The coupling surface of the armature winding 4 can be arranged parallel to the top surface of the first stator base 1, so that the armature winding 4 and the first stator base 1 can have a gap therebetween.

[0036] In combination with Figure 3When the armature winding 4 drives the mover module 20 to move along the conveying direction, the first stator base 1 does not interfere with the movement of the mover module 20, and during the movement of the mover module 20, the mover module 20 can always be arranged opposite to a part of the first stator base 1. By arranging the first sensing structure 7 on the first stator base 1, the first sensing structure 7 can detect the position of the mover module 20 during the movement of the mover module 20. Similarly, by arranging the second sensing structure 8 on the stator body 3, the second sensing structure 8 can also detect the position of the mover module 20 during the movement of the mover module 20.

This double detection method can check each other, reduce errors, improve the overall position detection accuracy, and prevent the same installation error from adversely affecting the first sensing structure 7 and the second sensing structure 8. In addition, by distributing the first sensing structure 7 and the second sensing structure 8 on both sides of the guide rail 5, the space can be used more effectively, and the components can be prevented from being concentrated on one side of the guide rail 5, so that the stator module 10 is more compact.
