High angular velocity up to 6600 deg/s

High angular acceleration

High bi-directional repeatability up to <5 arcsec

Sophisticated control & drive systems

Analog encoder interface and wide range of
RS422 interpolation factors

Perfectly fits with 8MTL series linear motor
high resolution stages

Standa 8MRL series rotation stages are based on direct drive torque motors in order to avoid mechanical inaccuracies (e.g. backlash) and reach high dynamical response of rotation system.

Ironless design of motor allows high acceleration and high velocity and it perfectly suits for a start-stop application which is especially important in: 3D printing, laser fabrication, wafer scanning or PCB etching applications.

High quality bearings and feedback system allows user to reach high positioning accuracy. Mechanical accuracy of stages is personally mapped using laser autocollimator in order to avoid constant inaccuracy. User is allowed to choose up to x200 interpolation using Standa external interpolation system or fit necessary servo controller with internal interpolation circuit for higher resolution of stage. 8MRL series stages are capable to operate with <4 arcsec bi-directional repeatability.

* - Encoder can be equipped with external interpolation circuit which will result differential RS422 encoder interface.
** - Resolution is indicated using analog encoder interface. While increasing the factor of external interpolation circuit the higher resolution can be adjusted for specific applications.
