Product overview
The high-precision PIglide IS XY planar scanner with air bearing has a flat design and is an alternative to the stacked XY stages. The efficient, compact design saves space in machines with limited installation space.
PIMag® magnetic direct drive
3-phase magnetic direct drives do not use mechanical components in the drivetrain, they transmit the drive force to the motion platform directly and without friction. The drives reach high velocities and accelerations. Ironless motors are particularly suitable for positioning tasks with the highest demands on precision because there is no undesirable interaction with the permanent magnets. This allows smooth running even at the lowest velocities and at the same time, there is no vibration at high velocities. Nonlinearity in control behavior is avoided and any position can be controlled easily. The drive force can be set freely.
Operation with digital controllers from leading manufacturers offers advanced control algorithms for improving the dynamics and error compensation.

Note on straightness and angular errors: Dependent on the flatness of the surface, on which the stage is mounted.
Note on the velocity and acceleration: It can be limited by payload, controller, or drive performance.
Note on the permissible push force: Assumes that the payload center of gravity is centered no more than 50 mm above the motion platform. The stage is designed for horizontal operation only.
Note on the sensor resolution: Assumes a 4096x interpolation. Contact PI for the use of other factors.
Note on the positioning accuracy: Improved accuracy can be obtained with controller-based error compensation. The stage must be ordered with a controller from PI to reach these values.
Accuracy values assume short duration and do not consider the long-term effects of thermal drift on the stage.
Note on the 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.
All specifications apply per axis, if not otherwise described.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
