Ultrasonic Motor Powers New Line of Linear Positioning Stages: Fast, Cost-Effective, Low-Profile

Auburn, MA, piezo system specialist PI announces the M-692 series of low-profile, ultrasonic linear translation stages designed for high-speed positioning tasks with limited space

Backlash-Free, with Linear Encoder

These stages are the lowest profile, closed-loop, linear motor-equipped, micropositioning systems in the industry. Two standard versions are available: M-692.1U4 with 20 mm stroke and M-692.2U4 providing 90 mm. Both versions are equipped with integrated linear encoders for backlash-free positioning. The stages can be arranged to form compact XY systems.

Scalable Design, OEM Versions, Vacuum Compatible Versions

The M-692 design is scalable and can be varied to provide different travel ranges to 300 mm for OEM quantities. Vacuum-compatible versions are also available on request.

Optimized Controller and Drive Electronics

For optimum performance, the highly specialized C-867 motion controller is available. This dedicated ultrasonic motor controller also integrates the drive electronics to generate the ultrasonic oscillations for the piezoceramic element. Furthermore, the controller features a number of special characteristics to address the requirements of ultrasonic motors such as continuous automatic drive frequency adjustment and dynamic parameter switching for optimized dynamics and settling behavior.
