Motorized Rotation Stage, 80 mm, Stepper Drive
Model: RVS80PP
Product Series Overview
RV High Performance Stepper Motor Rotation StagesThe RVS80PP Rotation Stage does not use an encoder. Instead, position is attained by the number of commanded steps and micro-steps. The high output torque of the stepper motor, combined with extensive performance tests, ensures position accuracy as long as the recommended load, torque and payload inertia are not exceeded. The RVS80PP provides very high motion sensitivity with good linearity between commanded micro-steps and the actual motion of the stage at a very reasonable price. 80 mm diameter.
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.
