AI Technical Summary
Technical Problem
In planar drive systems, how to ensure sufficient energy supply to the process equipment arranged on the mover, especially the energy supply during the movement of the mover.
Method used
An energy transmission structure is constructed on the stator unit, and a matching transmission unit is set on the mover. Energy transmission is achieved through magnetic coupling or non-contact induction coils. The mover is automatically charged when it moves above the stator surface, which simplifies the energy transmission process.
Benefits of technology
