The Piezo Miniature Stepping drive principle enables nanometer precision and high drive force.
Piezoelectric Stepping Motor is a new type of bionic piezoelectric actuator, which is driven by multiple groups of multi-dimensional piezoelectric actuator units according to the step-by-step multi-group action logic to realize the linear motion of the motor mover.
It features small size, high drive force, high holding force under static conditions, and no thermal power consumption. It can achieve high subdivision in a single step to achieve high resolution at nanometer level, and the step-by-step motion mode can achieve a large motion stroke at millimeter level.
