Abstract
A direct-drive system, including a base provided with a guide rail and a stator assembly; and at least one slide spaced from the base and fixed to the base by means of the guide rail. A mover assembly arranged opposite to the stator assembly is fixed to the at least one slide, and the mover assembly interacts with the stator assembly to drive the at least one slide to slide on the guide rail. An orthographic projection of the guide rail onto the base along a sliding direction of the at least one slide falls at least partially at an outer side of the base. The guide rail structure is first contacted when the modules are spliced, so as to ensure smooth sliding of the direct-drive system and reduce the difficulty of assembly and maintenance of the system.
