PI offers three advanced types of ceramic, nonmagnetic linear motor actuators that can replace classical actuators in medical and pharmaceutical applications.
PI's new line of compact ceramic piezo motors and actuators replaces classical actuators and motion control components in medical and pharmaceutical applications.
The motors and actuators are sterile and require no lubricants.
They feature high speed, millisecond responsiveness, are vacuum compatible and nonmagnetic.
High-speed actuators and zero-wear flexure designs are also available.
medical and pharmaceutical applications include: precision motion control, optics and imaging, fast valve control, applications in high magnetic fields, vacuum, liquid dispensing, fast pumps, scanning microscopy, OCT and MRI.
PI offers three advanced types of ceramic, nonmagnetic linear motor actuators that can replace classical actuators.
The three types are distinguished by force, travel range and speed and precision.
For short travel ranges (up to 0.5mm) with high forces and very rapid response (submillisecond feasible) PiezoMove Flexure Actuators are recommended.
Alternatively, theoretically unlimited travel ranges are provided by both the PILine and Nexact linear motor actuators.
Whereas the faster motor actuators (PILine) provide speeds up to 800mm/s, the Nexact type motor actuators feature higher resolution and forces.
In contrast to servo or stepper motor actuators, the piezo ceramic linear motors effect linear motion directly, without the need to transform rotation with gears and leadscrews.
Backlash and wear are eliminated and the drive is maintenance-free.
Piezo ceramic actuators exhibit high stiffness and are self-locking when powered down with nanometre position stability, and zero heat dissipation or servo-dither at rest.
