New URS precision rotation stages from Newport

Newport Corporation (www.newport.com), a global leader in photonic and laser solutions that “Make, Manage and Measure Light”, is proud to announce the release of the URS50BPP and the URS50BCC precision rotation stages that feature 360°, continuous motion. These new stages have the smallest footprint of 50mm in size, and are offered in very affordable price, while maintaining the high performance of URS motion product family from Newport.

The URS50BPP and the URS50BCC provide very low wobble and backlash-free, continuous rotation with extremely high MTBF of up to 20,000. Competitively priced, the high-performing rotation stages feature large stage performance in a very small package. The two stages also offer exceptional 6µm eccentricity and easy integration.

The URS50B’s feature a one of a kind, two-part bearing design with pre-tempered bearings and steel gears to ensure long-life motion positioning and precision. The URS50BCC, the DC-motor version with embedded index pulse for precision homing, is best suited for demanding applications that need bi-directional positioning.

The economical URSBPP stepper motor version is ideal for less demanding, yet precision rotation applications. Each URS50B has a cable URS50B for plug-and-play compatibility with XPS, SMC and ESP.

IP66-Rated Direct-Drive Rotary Stages from Aerotech

The ASRT is an IP66-rated, direct-drive, sealed rotary stage that provides precise angular positioning in hostile environments where dirt, dust, cutting fluids and fluid jets are present. Applications range from industrial machining automation to precision sensor positioning in hostile environments, and the ASRT is also an effective solution for precise rotary motion in product environmental test and range tracking applications.

The ASRT is offered with either high accuracy encoder or magnetic encoder feedback. Unlimited travel is standard, with an optional limited travel model also available. Three different models cover a wide range of load and torque requirements.

The ASRT series uses Aerotech’s brushless, slotless motor that has no brushes to wear, no gear trains to maintain, and high acceleration and high speeds. The low inertia and zero backlash make the ASRT the ideal solution for applications requiring frequent directional changes. In addition, Aerotech manufactures a wide range of servo amplifiers and advanced controllers to provide a complete, integrated package.

Dual large-diameter bearings are used to maximize performance with respect to tilt error motion (3 arc sec), moment stiffness, and repeatability (1 arc sec). The large diameter bearings permit large payloads (up to 175 kg) without compromising performance.

Maximum rotary speeds are from 100 to 200 rpm. The ASRT includes an electrically grounded shaft and housing to protect against electrical shock and eliminate RF re-radiation, and housing grounding points are included. Circular sealed connectors are standard, while options include desiccant cartridge, air purge, and mounting flange accessory.

A polymer-based paint on the housing and a hard-coated tabletop prevent corrosion. The stage has optional brown, green, grey, black, and white paint colors. Standard operating temperature is 0 to 70°C. Operation below freezing requires the optional air-purge and desiccant, with air-purged stages operational from -20 to 70°C.

Rotary Stage features Compact Package and Accurate Positioning

RTHM-100 compact rotation stages are designed to rotate optical components and small tooling in the confined spaces of the manufacturing processes for fiber optical components and semiconductor devices, fiber optic alignment, laser diode research, bio-medical applications and inspection systems.

The lightweight design feature low 32 mm profile height and incorporates anodized aluminum body with pre-loaded ball bearings with run-outs of 5 microns. This proprietary bearing design provides smooth rotation with minimal wobble.

A precision ground worm gear produces consistent driving torque to the rotor and eliminates variations in the motor current.

RTHM-100 stages feature an angular resolution 0.1 arc-sec, which may be achieved with either DC Servo or stepper motor controls.

The stages are equipped with a reference home sensor. RTHM-100 stages can run in continuous or start/stop rotation modes and mounted horizontally or vertically.

These stages feature zero backlash, large 50 mm center aperture and can rotate loads of 20 kg over unlimited rotation angle.

High Speed Piezomotor Rotary Stage from PI

San Francisco, CA — PI (Physik Instrumente) L.P. introduces a new ultra-low profile (0.6”), direct-driven, high-speed rotary stage based on its proprietary PILine® piezomotor drive technology at this year’s SPIE Photonics West conference. The new ultra-low profile (0.6”), direct-driven, high-speed rotary stage is based on PI’s proprietary PILine® piezomotor drive technology.

The M-660 stage reaches top speeds of 720 degrees/sec. and resolution to 40 µrad (8 arcsec). Its self-locking ceramic drive holds the position steady at rest, with no energy consumption and heat generation. A directly coupled precision optical encoder provides phase lag-free, backlash-free feedback to the servo controller.

Motorized Rotary Stage

Greenville, DE - Servo2Go has just added a new high performance rotary stage to its broad range of positioning systems.

Manufactured by Zaber Technologies Inc., the new T-RS60 rotary stage provides precise, continuous 360° rotation in a compact package. The robust bearing design allows the stage to handle up to 45 kg (99 lb) of load. A precision worm gear provides a 120:1 ratio allowing a stage resolution of 0.00023°. The built-in controller makes set-up a snap: just connect the stage to a computer and it is ready to use.

Zaber’s T-RS60 Series of precision motorized rotary stages are stepper motor driven, worm gear rotary stages capable of a full 360° rotation. Each rotary stage has an integrated microstepping stepper motor controller, offering high resolution daisy-chainable operation.
