Omni™ Series – OmniRH

Direct Drive Rotary Actuators with Large Through Hole

The OmniRH Series rotary stages enable OEMs to achieve smooth and accurate motion profiles and conveniently route cables and other system elements via a large through hole. Built with Omni™ direct drive motors from Applimotion, PurePrecision™ optical encoder technology from MicroE and precision bearings, the OmniRH rotary stages provide the benefits of direct drive rotary motor performance in a standard NEMA 23 motor package.

  • High-performance direct drive motor technology and high precision encoder
  • Integrated motor, encoder, and bearing makes it easy to upgrade existing NEMA 23 stepper or servo motors
  • High mechanical stiffness and low rotor inertia for efficient control of highly dynamic axes
  • Low cogging for accurate and smooth motion
  • Axial through hole for convenient routing of cables, optics, sensing technologies, and other system elements
  • Compatible with a wide range of drives and controllers
