The linear motor stator 7 is used to drive the linear motor mover 8 to move. A steel belt 3 is provided between the tops of the two side plates 5. Through grooves 9 are provided at both ends of the mover seat 2. The two through grooves 9 are connected, and the steel belt 3 is passed through the two through grooves 9.

[0028] The completely enclosed structure formed by the base 1, end plate 4 and side plate 5 of the present invention effectively isolates the influence of the external environment on the working area of ​​the linear motor, greatly reduces the problem of motor performance degradation or increased failure rate due to the entry of pollutants such as iron slag, dust, and moisture, and significantly improves the reliability and service life of the system. The steel belt 3 serves as a guide medium and is positioned through the through groove 9 on the mover seat 2, which not only simplifies the design of the entire module, but also reduces manufacturing costs and maintenance difficulties, while further improving the positioning accuracy of the system. The enclosed design allows the present invention to be easily integrated with other automation equipment or control systems, allowing users to flexibly configure it according to actual needs to meet the specific requirements of different applications.

[0029] In this embodiment of the fully enclosed single-axis module, the mover seat 2 includes an upper seat 10 and a lower seat 11.
