APRL Series

The APRL series uses porous material as the air support, has a large size air bearing surface, can produce high stiffness and large load capacity, not only has excellent axial and radial error motion, but also has excellent tilt error motion. The design of the APRL series direct drive rotating platform has been optimized to minimize the height of the platform and reduce the error associated with "stacking.

Product features:

High response speed
No mechanical contact
Thin flat design
Design of double grating ruler reading head with excellent speed stability
High torque output, frameless direct drive motor
Excellent error motion and swing performance
Flexible configuration options (customizable hollow version)
resolution 0.01arcsec, repeat positioning accuracy 1.5 arcsec, positioning accuracy 4 arcsec

Remarks:

The default test point position is 25mm above the table, and the single-axis index and the performance index of the multi-axis system are related to the actual load and the position of the working point;
For higher demand, it needs to be equipped with Heidelhain grating ruler and linear amplifier;
No load, need to configure the corresponding power of the linear amplifier,
The payload specification assumes that the payload is centered on the axis;
In order to ensure the implementation and repeatability of the specification over a long period of time, the ambient temperature must be controlled within a range of 1°C per 24 hours.
