| Abstract: | A large-travel high-resolution step rotary micro-actuator with a discrete layout was developed based on the step moving principle. A flexible electromagnetic hinge was used to realize the anchoring/lossening of the rotor and a piezoelectric pile as the driver and a flexible hinge was used to transform the linear motion of the piezoelectric pile into the rotary motion, thus a precise large-travel step rotary actuation was realized. Experiments show that the developed actuator is characterized by fast anchoring, high resolution, and large travel, being applicable in the sophisticated micro-manipulations. |
