The RV Series rotation stages provide high-precision angular positioning accuracy combined with high load capacity. There are five stage sizes and six drive configurations available, optimizing load capacity, torque, speed and resolution for a variety of operating conditions.

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. The largest RV stage can bear up to 6500N or rotate up to 80 °/s, while maintaining less than 4 um eccentricity.

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 (0.00025° resolution with RVS80CC) on the standard configurations. For more demanding applications, the HAT and HAHLT options are available on the RV120 to RV350 models. These stages are equipped with a direct reading optical encoder attached to the moving platen for superior resolution and accuracy.
The selection of the drive configuration should be based on the precision and speed requirements relative to the inertia of the payload.

Motor Drive Versions

Stepper motor-driven stages are available in full step PE and ministep PP versions. The mini-step drive version (PP) enables high angular speed motions up to 20 °/s. The larger models, RV120PP to RV350PP, feature a worm mounted rotary encoder for improved accuracy and repeatability. The encoder also provides a method for detecting motor stalling, an important feature for applications with high acceleration ramps and high torques or payload inertias.

The RVS80PP 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. The full-step PE version is equipped with a reduction gear providing higher torque. This version is only available on the models RV120 to RV350 and is recommended for high inertia payloads and vacuum applications.

DC motor-driven stages are available in high speed (CC and HAT) and high torque (CCHL and HAHLT) versions.The CC and HAT versions enable speeds up to 80 °/s. The HAT features a high-resolution direct reading encoder and tachometer for superior repeatability, position stability and speed regulation. The CCHL and HAHLT versions are equipped with a reduction gear providing higher torque and payload inertia capacity. The HAHLT features a high-resolution direct reading encoder and tachometer for superior repeatability, position stability and speed regulation.

Q_V = 2700 N / 2 / (1 + 155 mm / 50 mm) = 329 N

Torque and Payload Inertia

The following table lists the maximum torque and the maximum payload inertia for all RV rotation stages. The maximum payload inertia equals the maximum kinetic energy that the rotation stage can absorb in the event of a sudden stop at the maximum speed. Likewise, this is the maximum inertia to accelerate from stop to the maximum stage speed in 250 ms. Some RV stages can handle higher payload inertias at reduced speed. For detailed information, please contact a Newport Applications Engineer.
