ABSTRACT:
The present invention provides a shear motion driven motion actuator. The motion actuator provides a plurality of driving modes to drive a main body, including the inertial drive mode, the friction drive mode and the scanning mode. The motion actuator comprises a base having a V-shape concave groove and a main body having a V-shape convex. A plurality of piezoelectric elements is provided on the base to drive the main body using the shearing deformation force of the piezoelectric elements. The present invention also provides motion control using a variety of driving modes to achieve stable, high resolution and linear driving of the main body along the base.
