- High-torque output - 600 N·m peak, 143 N·m continuous
- Rotational accuracy to ±9.7 μrad (±2 arc sec)
- Ideal for large payload motion simulation applications
- Payloads to 475 kg
- Variety of tabletop, encoder, and travel options
Aerotech’s AHTR direct-drive rotary stages feature a precision mechanical design coupled with a direct-drive, high-torque rotary motor. The AHTR excels in applications where high-torque, high-acceleration, and accurate rotary positioning are essential.
High-Torque Brushless Motor
Rapid acceleration and high torque are key features of the AHTR stage. Users can command rapid incremental or continuous rotary motion with the high-torque, direct-drive, brushless motor. With the direct-drive motor and precision structural design, the AHTR enables high-bandwidth motion for contouring or point-to-point positioning. It is the ideal rotary stage for motion simulation, laser steering applications, electro-optic sensor testing, resolver or optical encoder accuracy testing, antenna testing, and inertial navigation device testing where high-payloads are required.
To maximize stage lifetime, the AHTR series uses brushless motors. This motor design has the advantage of low-maintenance coupled with high acceleration and accurate positioning performance.
High Payload Capacity and Large Moment-Load Stiffness
The AHTR is designed with a large payload capacity and high moment stiffness to handle a variety of applications and unique payload mounting arrangements. Payloads up to 475 kg and moment loads up to 1600 N·m can easily be handled by the large angular contact bearings and structural design of this rotary stage.
