Description

Design Features

  • Available in 9 models to meet any load capacity, torque, and dimensional requirements
  • Delivers high torque output and smooth, stable motion with direct-drive, cog-free servo motor
  • Achieves excellent accuracy and repeatability with high-resolution position feedback
  • Supports generous payloads and provides exceptional stiffness
  • Offers integration and process flexibility with large-diameter clear aperture

The World’s Most Versatile, High-Precision Rotary Stages

Aerotech’s ADRT series of mechanical-bearing, direct-drive rotary stages is an excellent choice for applications that require fine precision, smooth motion, rapid accelerations, high speeds, large payloads, or any combination of these.

Dual, large-diameter bearings provide considerable payload capacity and moment stiffness. Combined with a slotless, brushless torque motor, ultra-smooth, high-speed motion is easily achieved. A selection of high-resolution position feedback devices allows for highly accurate and repeatable positioning performance.

The variety of features and options available with the ADRT series make it an excellent choice for seamless integration into multi-axis motion systems, subsystems, and machines. In addition to continuous 360° travel, ADRT can be equipped with limited-travel options and fail-safe holding brakes to mitigate against crash conditions and provide additional payload security. Mounting interfaces on all sides of the ADRT enable convenient payload mounting, counterbalancing, and integration into high-precision gimbals and azimuth-elevation assemblies.

Key Applications

ADRT stages are ideal for applications that require very precise rotary motion, combined with high torque, speed, and payload-carrying capacity, including:

  • Testing of sensors, MEMS, and other devices
  • Electro-optics testing and calibration
  • Indexing and alignment
  • Laser micromachining
  • Angular tracking
  • High-precision inspection of semiconductors, medical devices, and other components

Stable, Flexible Configurations Master Heavy Payloads

Dual large-diameter bearings and a precision-turned shaft help to minimize axis error motions while maximizing stiffness and repeatability. You’ll never have to compromise on performance when handling large payloads.

Further enhancing stability, the motor and rotary encoder are directly coupled to a common shaft. There are no position errors triggered by hysteresis, windup or backlash because ADRT does not have any gear trains or mechanical couplings.

All ADRT configurations deliver outstanding accuracy, smoothness and runout performance. Additionally, slip rings and rotary unions can be added upon request to ease integration of custom tooling. An optional holding brake is available to limit movement of the stage during large impulse loads or when power is removed from the motor.

T-slots allow ADRT to be mounted horizontally or attach to application-specific fixtures.
