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.
