1. A direct drive transmission system, comprising a mover unit and a stator unit driving the mover unit to move;
wherein the stator unit comprises a stator assembly, two first end covers fixed to two opposite circumferential sides of the stator assembly, and two first guide rails fixed to a side of the stator assembly facing to the mover unit and extending along a motion direction of the mover unit, the two first guide rails are arranged in parallel and spaced apart from each other; a side of each of the two first end covers facing to one first guide rail of the two first guide rails is recessed inwardly to form a first mounting groove, two ends of the first guide rail are respectively inserted into the first mounting groove;
wherein the mover unit comprises a mover assembly, two second end covers fixed to two opposite circumferential sides of the mover assembly, and two second guide rails fixed to a side of the mover assembly facing to the stator unit and extending along the motion direction of the mover unit, wherein the two second guide rails are arranged in parallel and spaced apart from each other;
wherein the two second end covers are respectively arranged directly opposite to and apart from the two first end covers, the two second guide rails respectively abut against the two first guide rails to form a slidable connection; a side of each of the two second end covers facing to one of the two second guide rails is recessed inwardly to form a second mounting groove, two ends of the second guide rail are respectively inserted into the second mounting groove; and the stator assembly drives the mover assembly to cause each second guide rail of the two second guide rails to move on a corresponding first guide rail of the two first guide rails.
