Direct drive transmission system

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 close to the mover unit and extending along a motion direction of the mover unit, the two first guide rails are spaced apart in parallel;
• 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 close to the stator unit and extending along the motion direction of the mover unit, the two second guide rails are spaced apart in parallel;
• 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;
• wherein end faces of the two first end covers and the two second end covers close to each other have orthographic plane structures;
• and
• wherein the direct drive transmission system further comprises a limiting structure fixed to a side of the stator assembly close to the mover assembly, an end of the limiting structure close to the two second end covers is located between the two second end covers, and the stator assembly drives the mover assembly to cause each second guide rail of the two second guide rails to move along a corresponding first guide rail of the two first guide rails, in such a manner that each second end cover of the two second end covers contacts a side wall of the limiting structure to be limited.
