Hollow Rotary Actuators

Hollow Rotary Actuators

The DGII Series is a line of of products that combine a high rigidity hollow rotary table with a closed loop stepper motor and driver package. It retains the ease of use of a stepper motor, while also allowing for highly accurate positioning of large inertia loads.

  • Integrated actuator and stepper motor makes design easier
  • Large-diameter hollow output table
  • Pulse Input, Pulse Input with RS-485 Communications and Built-in Controller (Network) type drivers
  • AC or DC Input

The gear-reduction mechanism employs precision gears along with a proprietary adjustment mechanism that eliminates backlash. The repetitive positioning accuracy from a single direction is ±15 sec., while lost motion in a positioning operation from two directions is 2 arc minutes. These characteristics make the DGII series the ideal choice for applications in which accurate positioning is a must.
