Abstract
The present disclosure provides a direct drive transmission system and a control method. The direct drive transmission system includes: a base plate, guide rails, a plurality of stators, a mover, a plurality of drivers, and a controller. The plurality of stators are configured to drive the mover to slide on the guide rails. 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 includes at least one first switching signal device and a plurality of second switching signal devices. The at least one first switching signal device aligns with a respective second switching signal device, and each second switching signal device is electrically connected to a respective driver or the plurality of second switching signal devices are all electrically connected to the controller.
