Direct drive transmission system and control method

Abstract

SUMMARY OF THE PRESENT EMBODIMENT A direct drive transmission system and control method is provided. [Solution] The direct drive transmission system includes a substrate, a guide rail, a plurality of stators, a mover, a plurality of drivers, and a controller, the stators are used to drive the mover to slide on the guide rail, the transmission lines on which each stator is located are arranged as a low-precision segment and a high-precision segment connected to each other, the direct drive transmission system includes a first switching signal device and a plurality of second switching signal devices, the first switching signal device and the second switching signal device are installed correspondingly, and each second switching signal device is electrically connected to a corresponding driver or both are electrically connected to a controller. The present invention can reduce the usage of the position feedback device and reduce the cost of the device by adopting the switching signal device instead of the expensive position feedback device in the low-precision segment. At the same time, the motion control in the low-precision segment of the mover is simple, so that the control cost can be reduced and the cost can be further significantly reduced.
