Motorized Rotation Stage, 160 mm, High-Torque Mini-Step Drive
Model: RV160BPP
Product Series Overview
RV High Performance Stepper Motor Rotation StagesThe RV160BPP High Torque Rotation Stage provides high-precision angular positioning accuracy combined with high load capacity. This 160 mm diameter stage features a Mini-step drive enabling high angular speed motions up to 20°/s. All RV stages are constructed of tool steel, with rotation accuracy ensured by ground bearing surfaces. A double row of preloaded bearings allows for high off-center loads in a reduced footprint. The single monolithic design offers improved stiffness without compromising dynamic performance. Precise rotation is ensured by a precision ground and hardened worm gear. A rotary encoder mounted on the worm gear shaft provides 0.001° position feedback resolution.
Steel Construction
The tool steel construction ensures enhanced rotation accuracy due to the ground bearing surfaces. The single monolithic design offers improved stiffness and thermal stability without compromising dynamic performance.
Highest Load Capacity
The double row of preloaded ball bearings allows for higher off center loads for its small footprint. The largest member of the RV stepper motor product family can bear up to 650 kg or rotate up to 20 °/s while maintaining eccentricity of less than 4 µm.
Full-Step and Mini-Step Stepper Motors
Full-step (BPE and PE) and mini-step (BPP and PP) versions of the RV stepper motor stages are available. The full-step version is equipped with a reduction gear to obtain higher torque and is primarily designed for applications requiring the direct positioning accuracy to be maintained to within the stage's mechanical resolution when power is switched off. The mini-step versions offer a 1/10-step per encoder count, enabling speed of up to 20°/sec. With the exception of the RVS80PP, these stages feature a worm-mounted rotary encoder for improved accuracy and repeatability and to detect motor stalling, an important feature for applications with high acceleration ramps and high torques or payload inertias. For the RVS80PP, position is attained by the number of commanded steps and micro-steps.
Vacuum Compatible Versions
Vacuum compatible verions of the RV series full-step stepper motor stages are available. They can be used in vacuum environment down to 10-6 hPa. Check out our vacuum products brochure for more information. Contact us today to discuss your application requirements.
