Product overview
The PIglide stage with air bearing and voice coil drive offers high velocity and acceleration in a compact package.
The contactless components of the motion platform ensure the highest performance, quality, and lifetime.
Voice Coil Drive Technology
Voice coil motors are direct drives. In direct drives, the force of the drive element is transmitted directly to the load to be moved without the use of mechanical transmission elements such as coupling, drive screw, or gearhead. Voice coil drives consist of a permanent magnet and a winding body that are located in the air gap of the magnetic field. When current flows through the winding body, it moves in the magnetic field of the permanent magnet. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications that require high dynamics and high velocities at limited travel ranges. High scan frequencies and precision positioning are also possible with these drives, because they are free of the effects of hysteresis.
Accessories and options
- PIglide filter and air preparation kits
- Single and multi-axis motion controller
Application fields
High-speed scanning, applications in manufacturing.
Thanks to the friction-free motion, no particles are formed, which makes PIglide stages ideal for cleanroom applications.

Note on pitch, yaw, straightness, and flatness: Dependent on the flatness of the surface, on which the stage is mounted.
Note on velocity and acceleration: Can be limited by the payload, controller or drive.
Note on permissible push force in Z: Assumes that the load's center of gravity is centered no more than 50 mm from the motion platform.
Note on sensor resolution and bidirectional repeatability: Assumes 16384x interpolation. Contact PI for the use of other factors.
Note on positioning accuracy, calibrated: Improved accuracy can be obtained with controller-based error compensation. The stage must be ordered with a controller from PI to reach these values.
Note on operating pressure: To protect the stage against damage, it is recommended to connect an air pressure sensor to the Motion-Stop input of the controller.
