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.

Linear Motor and Driver

High performance piezo linear translation stage with integrated non-magnetic cross-roller bearings. Body and structural elements are titanium. Piezoelectric elements use non-magnetic materials. Standard unit has 300 series stainless steel screws/hardware and the option for all non-ferrous screws/hardware is available. Highlights: vacuum environment compatible, magnetic environment compatible, and zero power / power off position lock.

Ultrasonic Motors and Drivers

The SUM-40 is a direct drive piezo ultrasonic motor with an integrated amplifier, controller, and optical encoder that gives the user closed loop control in a compact package.

The SUM-40NM is a direct drive piezo ultrasonic motor with an integrated optical encoder that gives the user closed loop control in a compact package. Despite its small size, the SUM-40NM boasts a continuous torque of 50 mN-m while the integrated optical encoder provides 130 microradian resolution.
