Motorized Rotation Stage, DC Motor, Continuous 360° Motion, URS50
Model: URS50BCC
Product Series Overview
URS Precision DC Motor Rotation StagesThe URS50BCC Rotation Stage provides precision 360° continuous motion in a low profile package. It meets the requirements of numerous research and industrial applications. This DC motor version is the recommended choice for applications requiring accurate bi-directional positioning. The high-torque DC motor provides the highest dynamic speed range and allows for rotating speeds up to 20°/s. 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. 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 stages to provide better support of higher or off-centered loads. Additionally, the flexible preloading system for the worm gear was improved to guarantee a minimum backlash operation with an MTBF of 20,000 hours.
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.
High Torque DC Motor with Ultra-High Resolution Feedback
The URS75BCC, URS100BCC and URS150BCC feature (not included on the URS50BCC) an ultra-high resolution 8,000 cts/rev rotary encoder with index pulse for precision homing and are recommended for applications requiring accurate bi-directional positioning. For the tightest position control, the rotary encoder is mounted directly on the worm screw. This eliminates most of the possible error sources associated with indirect read feedback devices. The high torque of some DC motor versions provides the highest dynamic speed range and allows for rotating speeds up to 80°/sec. The URS50BCC is the smallest version, and its motor encoder feature provides a very compact and easy to integrate version which can rotate up to 20°/s with 100 N maximum load capacity.
Proprietary Ball Bearings
Limit Switches
Except for the URS50 version, all URS stages feature adjustable limit switches to prevent over travel.
