The RV Series steel rotation stages combine high precision positioning and extremely high load capacities to operate in a large variety of conditions for scientific and industrial applications. Five stage sizes and four DC motor configurations are available. Closed-loop DC servo systems are the recommended choice for more demanding applications requiring either higher rotational speed, repeatability, accuracy or smaller minimum incremental motion (MIM).
Folded version for applications with space constraints and Stepper Motor version are also available.
High speed (CC and HAT) and high torque (CCHL, HAHL and HAHLT) versions of the RV DC motor stages are available. The high speed versions enable speeds up to 80°/sec. The high torque versions are equipped with a reduction gear which provides higher torque and payload inertia capacity. A rotary encoder is mounted on the worm gear shaft of the CC and CCHL versions. When superior repeatability, position stability and speed regulation is needed, the high speed HAT and high torque HAHLT versions feature a high-resolution direct reading encoder and tachometer. (RV120HAHL includes direct reading encoder, but no tachometer.)
For critical positioning applications, Newport offers error mapping upon request for RV-HAT and RV-HAHLT stages driven by our XPS advanced motion controller. We will measure, implement, and verify the results of this error map that will individually optimize each stage's position accuracy. In addition, multi-axis error mapping is also available. Measurements are made at 20.0 ±0.2 °C. A certificate of calibration will be provided with your stage. Actual data may also be provided upon request.
