Abstract
A piezo-actuated braking system for a stepper motor. The braking system has a disk fixed to the output shaft of the stepper motor. Further, the braking system includes a piezo-actuated brake having a clamping structure, including two brake elements positioned in alignment on either side of the disk. The piezo-actuated brake includes a piezoelectric element connected to the clamping structure to move the brake elements together, thus applying a braking force to the disk. Various embodiments of the braking system along with related methods are also described.
