Motorized Rotation Stage, Vacuum, Stepper Motor, URS75

The URS75BPPV6 Vacuum Compatible Rotation Stage provides precision 360° continuous motion in a low profile package. It meets the requirements of numerous research and industrial applications and is directly compatible with our VP, XM, GTS and other series of linear stages. This 0.5 N·m maximum torque stepper motor version is a more economical for less demanding applications. All URS rotation stages feature a proprietary 4-point contact ball bearing. The unique, 2-piece design of the URS provides a low-profile compact stage with exceptional stiffness, high reliability and outstanding wobble and eccentricity.
Note: The cable supplied with the stage is not vacuum compatible due to various feed-through configurations and customer preferences. Please contact Newport for vacuum compatible cable options.
Tilted Worm Screw
The tilted worm screw arrangement allows for 4 symmetric mounting holes as compared to other designs that only feature 2 or 3 mounting holes. This enables the URS-B stages to provide better support of higher or off-centered loads. Additionally, the flexible preloading system for the worm gear was improved to minimize backlash during operation.
Economical Micro-stepping Stepper Motor
The stepper motor version is a more economical version for less demanding applications. When used with motion controllers with high micro-step capability, like the XPS or ESP30x, low noise operation and very small incremental motions are guaranteed. The stepper motor versions do not use encoder feedback, but reach a position by the number of commanded steps and microsteps. For this purpose, the stepper motor is directly attached to the worm screw using a proprietary bellows coupling that has a high torsional stiffness, eliminating the need for a gear or belt drive. The high output torque of the stepper motor minimizes the risk of lost steps and provides good linearity between commanded microsteps and the actual motion of the stage.
Proprietary Ball Bearings
Limit Switches
Except for the URS50 version, all URS stages feature adjustable limit switches to prevent over travel.
