Direct drive transmission system and control method

A direct drive transmission system, comprising:

• a base plate;
• guide rails fixed to the base plate;
• a plurality of stators fixed to the base plate along an extension direction of the guide rails and sequentially connected to each other;
• a mover slidably fitted to the guide rails and arranged to space from the plurality of stators;
• a plurality of drivers;
• and
• a controller electrically connected to the plurality of drivers;
• wherein each driver of the plurality of drivers is electrically connected to a respective stator, and the plurality of stators are configured to drive the mover to slide on the guide rails;
• and wherein a transmission line composed of the plurality of stators is configured to have at least one low-accuracy segment and at least one high-accuracy segment connected to each other;
• the direct drive transmission system further comprises at least one first switching signal device fixed to the mover, and a plurality of second switching signal devices fixed to the base plate, wherein each stator of stators located in the at least one low-accuracy segment of the plurality of stators is in correspondence to a respective second switching signal device, the at least one first switching signal device aligns with a respective second switching signal device, and each second switching signal device of the plurality of second switching signal devices is electrically connected to a respective driver or the plurality of second switching signal devices are all electrically connected to the controller.
