Motorized Rotation Stage, 240 mm, High-Torque DC Drive

RV High Performance DC Motor Rotation Stages

The RV240CCHL High Torque Rotation Stage provides high-precision angular positioning accuracy combined with high load capacity. This 240 mm diameter stage features DC drive equipped with a reduction gear providing higher torque and payload inertia capacity. 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 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.)

Configurable Limit Switches

Most of the RV models are designed with optical limit switches to limit movement to 170°. These can be enabled or disabled for complete 360° motion with a simple "Allen" wrench.

Metrology Report Included at No Additional Cost

Newport guarantees specification values which are measured and recorded following ASME B5.57 and ISO 230-2 standards. The typical performance values are two times better than the guaranteed specifications.
