RodDrives may replace classic drive elements like motor / leadscrew assemblies or magnetic linear drives, whereby the ultrasonic piezo linear motors reach significantly higher velocities. They consist of a rod which is preloaded by PILine® piezo linear motors from two sides. Depending on the way of integration, either the rod or the motor block is coupled to the moving platform.
Variable Travel Ranges and Forces
The maximum travel range of the RodDrive is determined by the length of the rod and is basically unlimited. Customized adaptations in terms of operating and holding forces are feasible by varying type and number of the motors used.
RodDrives represent a level of integration between PILine® OEM piezo linear motors such as the U-164 (see link) and guided micropositioning systems such as the M-683-series stages (see link).
Advantages of PILine® Micro Positioning Systems
RodDrives employ a patented ultrasonic drive developed by PI. The highly compact, integrated piezo motors can provide velocities of up to 0.5 m/s together with high resolution. The ceramic motors are preloaded against the rod, thus providing a holding force at rest. The result is a very high position stability, without the heat dissipation common with conventional linear motors. There are no gears, leadscrews or other mechanical components to contribute play or backlash.
Optimized Drive Electronics
PILine® piezo motors require a special drive electronics to generate the ultrasonic oscillations for piezo ceramic elements. The drive electronics is available as low-priced OEM board, standalone device or integrated inside a controller and therefore not included in the delivery.
