RSR Series Direct Drive Rotary Stages
RSR Series Direct Drive Rotary Stages
Our RSR series is a high-precision, low-profile rotation stage driven directly by a brushless motor instead of a belt drive or worm gear. It's available in 50mm, 100mm, 150mm, 200mm, and 300mm sizes. Whether your application requires moderate or ultra-precision, our inventory has a suitable stage.
A high-resolution, hysteresis-free, non-contact encoder mounted directly to the rotary stage hub provides feedback to ensure correct positioning. Multiple interpolation options are available with resolutions down to 0.021 arc-sec. For very high-resolution feedback without sacrificing speed, an encoder with an analog 1-volt p-p output is available for interpolation by the controller. We have designed the RSR series to accept an optional dual-read-head encoder for ultra-precision accuracy.
A preloaded, circular crossed roller bearing gives the RSR good stiffness and load capacity within a low profile. This precision bearing also provides the RSR with its low axial radial runout and low wobble errors. To accommodate the routing of wires, vacuum lines, or an optical pathway, our direct drive rotary motor stage has a large open aperture.

Advantages of Our Motorized Rotation Stages
The RSR series delivers these benefits:
- No backlash: Replacing gears and belts with a direct drive rotary stage and brushless motor eliminates the backlash often experienced in conventional transmission systems. As a result, you'll enjoy smooth, high-precision operations.
- Better positioning sensitivity: The RSR series uses a high-resolution encoder for exceptional precise positional control, qualifying it for high-precision applications.
- Higher speeds: Due to the eliminated backlash, our products can achieve high speeds from 331 rpm to 1,333 rpm. These speeds are suitable for high-performance applications like inspection and laser processing.
- Smaller envelope: Our stages have smaller envelopes for increased precision motion control.
- Zero drive maintenance and wear: We integrate our motorized rotation stages with frictionless motors, extending their service life.
- High repeatability: We have mounted the high-resolution encoder directly on the stage to achieve significant repeatability and accuracy.
These advantages make the RSR series well-suited for applications that require high rotational accuracy, excellent positioning sensitivity and repeatability, and fast move and settle times.
