Abstract
Provided is a piezo-actuated planar motor, comprising a planar substrate and a mover installed on the planar substrate, the piezo-actuated planar motor further comprising: at least one piezo driving leg which is disposed on said mover so as to drive said mover to move on said planar substrate omnidirectionally in the plane. Further provided is a method of driving a planar motor by using piezo driving legs, which implements three movement modes, i.e., a sliding mode, a walking mode, and a fine tuning mode. The sliding mode has the fastest speed of motion, the walking mode has a relatively slow speed of motion but has a high positioning accuracy and a high-accuracy tracking capability, and the fine tuning mode is used for the adjustment of the planar motor at a final position and has the highest positioning accuracy. The piezo-actuated planar motor of the present invention can effectively overcome the defects of a small movement range and a low speed in a conventional nano-positioning platform.
