Motorized Rotation Stage, 160 mm, High-Torque DC Drive, Direct Encoder
Model: RV160HAHLT
Product Series Overview
RV High Performance DC Motor Rotation StagesThe RV160HAHLT Rotation Stage provides high-precision angular positioning accuracy combined with high load capacity. This 160 mm diameter stage features DC drive equipped with a reduction gear. It is equipped with high-resolution direct reading encoder and tachomet for for superior repeatability, position stability and speed regulation regulation 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.
Steel Construction
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 DC motor product family can bear up to 650 kg or rotate up to 80 °/s while maintaining eccentricity of less than 4 µm.
High Speed and High Torque DC Motor Versions
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.)
Metrology Report Included at No Additional Cost
Error Mapping Services
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.
