Ultrasonic motor powers new line of linear positioning stages
12 April 2010
PI has introduced the M-692 series of low profile, ultrasonic linear translation stages for high speed positioning tasks with limited space. These stages are believed to be the lowest profile, closed-loop, linear motor-equipped, micropositioning systems in the industry. Two standard versions are available: M-692.1U4 with 20mm stroke and M-692.2U4 providing 90mm. Both versions are equipped with integrated linear encoders for backlash-free positioning. The stages can be arranged to form compact XY systems.
The M-692 design is scalable and can be varied to provide different travel ranges to 300mm for OEM Quantities. Vacuum-compatible versions are also available on request.
For optimum performance, the C-867 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 behaviour.
