Akribis Systems has introduced its SGR Series rod motor positioning module featuring repeatable, submicron accuracy. As equipment and systems in dynamic industries like semiconductor, biotechnology, precision assembly and battery manufacturing continually get smaller and faster, submicron-level positioning accuracy is critically important.
The SGR module comes equipped with a high-precision Akribis RDM-A Series coreless direct drive rod motor, linear guide rail and integrated optical encoder. The unit is available with strokes from 70 to 720 millimeters as well as custom strokes, and it delivers 3.1 to 114.8N of continuous force (Fcn) and 9.3 to 344.5N peak (Fpk).
The integrated RDM-A rod motor leverages the high torque constant of direct drive technology, while the air gap between the coil and motor ensures force consistency. Thanks to the rod motor’s ironless construction, it also ensures cog-free operation. A contact-free optical incremental encoder provides 0.2 μm resolution for exceptional repeatability. Further features of the SGR rod motor module include:

Compact size

Simple structure

Strong aluminum housing

Economical configuration 

In addition to use in the semiconductor, biotechnology, precision assembly and battery manufacturing industries, the SGR Series rod module is also appropriate for glass and LCD panels, medical equipment, printing machines, laser processing and precision assembly.
