Direct shaft coupling
The encoder’s hollow shaft allows it be directly coupled to the mating shaft. No additional rotor coupling is required. The high rigidity permits higher control-loop bandwidths while significantly reducing inaccuracy and installation complexity.
Rotary encoders with a bearing and stator coupling ensure consistently high accuracy. Thanks to optimally matched components, system accuracies of down to ±18 arc seconds are attained.
The stator coupling compensates for play between the motor and the rotary encoder, thereby correcting inaccuracy. Even tilt and axial play of up to ±0.5 mm can be reliably compensated for. The stator coupling also facilitates easy mounting to the plane surface.
The rotary encoders of this series feature high ruggedness and reliability in a compact design with an outer diameter of just 35 mm. Their small footprint makes them ideal for very tight installation spaces.
