Piezo Motors
DSM offers a non-magnetic, high vacuum compatible, piezo motor for longer travel applications and a rotary ultrasonic motor in both a compact integrated unit and a non-magnetic version. Where actuators/stages rely only on piezoceramic stack expansion to move and so have limited travel, piezo motors have practically limitless linear or rotational travel by using complex piezo structures and drive/control electronics to move. Piezo motors can be vacuum compatible, non-magnetic and hold position with zero-power. DSM can scale and modify existing architectures to meet customer specifications.
3 ready-to-order models are available. Contact us for customized solutions.
