Linear Shaft Motor Stage Offers Nanoprecision

Radford, Va. - Nippon Pulse America’s new SCR100 stage is an ultra high precision, compact single axis stage that integrates a slide guide, encoder, and Linear Shaft Motor. It offers a wide range of advantages for ultra high performance and accuracy applications. The Linear Shaft Motor is a coreless direct drive linear motor which has zero cogging, allowing for higher resolution, speed, and continuous force than standard stepper motors and piezo servomotors. 

The SCR100 stage is a moving magnet design, which locates all cables and connectors in the stationary base. The absence of any moving cable means a clean and compact design and eliminates motion errors due to cable forces. The precision ground cross roller way provides high stiffness and smooth motion. Together they are capable of supporting higher torque levels due to offset loads with travels from 50mm to 300mm. The non-contact Linear Shaft Motor and optical linear encoders are self-contained inside the stage, making it a low-profile compact solution. The built-in non-contact optical linear encoder is available with resolutions from 1 micron to 10 nm with digital output. The sub-micron resolution results in a high accuracy stage, which is laser tested for optimum performance.

The SCR100 stage has the added benefit that any standard digital servo driver can drive the SCR100 stage. Any two SCR stages will bolt directly together to form a very stiff, compact X-Y stage. Two SCR stages can be supplied compounded as an X-Y stage to insure true orthogonal orientation.

Heason releases new MMG-AL linear motor driven positioning stage

Heason Technology (http://www.heason.com) has introduced an all-new high throughput version of the Mini-MAG linear motor driven positioning stage from distribution partner Dover Inc. (www.dovercorporation.com).

While the new, ultra-compact MMG-AL still incorporates the main design and dimensional characteristics of the range, it replaces the stainless steel base and top plate with an optional single phase linear motor and simplified high grade aluminum construction. When combined, this results in minimized moving mass with the added benefit of lowered stage and drive amplifier costs, as well as higher bandwidth performance.

The small footprint stage comes in four travel options from 25mm to 150mm. It has a nominal width of 80mm and features Dover’s MAG moving magnet motor technology, which does away with the need for moving motor cables. It also features a durable side mounted tape style optical encoder, which comes in a selection of positional resolution from 0.1 microns to 0.005 microns. With stage flatness and straightness across the new MMG-AL range from 4 microns to 8 microns, and with specified bidirectional repeatability to within +/- 0.5 microns, the 25mm travel version’s positional accuracy is 3 microns with a 0.1 micron encoder.

The MMG-AL range has less than two-thirds of the mass of its stainless steel counterpart and 8kg nominal load capacity with an optional higher load capacity. The positioning stage can meet the dynamic performance needed for the most demanding high precision production systems, thanks to its maximum acceleration of 22m/sec2 and velocity of 0.5msec. The stage caters to the need of high throughput imaging industries, as well as ideal for any precision position application, where in-position stability and step-and-settle times are the main requirements.

High Speed, High Force, Sub-micron Positioning, Voice Coil Stage Features 20 mm Aperture

Sunnyvale, Calif. – Equipment Solutions’ VCS-2020 Voice Coil Stage features a 20 mm diameter aperture, 20 mm (0.7874 in.) travel, and sub-micron (1.1811 10^-6 in.) positioning resolution. An integrated Analog position feedback sensor assures 100 nanometer (3.937 10^-6 in.) repeatability.  The cross-roller voice-coil stages are self contained, compact, and can be mounted in a horizontal or vertical axis.

The compact 117 x 75 x 81 mm (4.60 x 2.96 x 3.18 in.), low mass, voice coil stage is a fully self-contained system including a high precision cross roller stage, voice coil actuator, analog position sensor, servo amplifier and servo controller. The low-inertia cross roller stage is integral to the standard threaded “C” lens mount and motor coil for tip/tilt free motion. Custom lens mounts are available. The voice coil motor is rated at 17.8 N (4 lbs.) continuous force and 71.8 N (16 lbs.) peak for 10 seconds and is cleanroom compatible. For easy integration into a new or existing application, the VCS-10H Voice Coil Stage has multiple sets of mounting holes on several surfaces.

This compact voice coil stage is ideal for such micro-positioning applications as scanning interferometry, disk drive testing, auto focus systems, surface structure analysis, confocal microscopy, biotechnology, and semiconductor test equipment.

Integrated UMR-TRA XY Stages from Newport

Irvine, CA - Newport Corporation announces the UMR-TRA XY Stages. The new line of integrated XY stages are built from reliable, industry-standard UMR linear stages and TRA actuators. Affordable and compact, the small footprint measures only 90 mm wide and 38 mm high, including the base plate. The UMR-TRA-XY stages are specially designed for applications in confined spaces, making them an excellent choice for a wide range of motion control tasks in research and industry.

The UMR-TRA has 12.5mm travel and is available in English or metric versions, DC or stepper motor, and a vacuum-compatible stepper-motor version which is compatible down to 10-6 hPa. For research, the stage is ideal for use in vacuum applications and other space-restricted setups. For industrial applications, the robust stage is qualified for laser beam positioning and can withstand high machine accelerations. The UMR-TRA is compatible with all of Newport’s popular motion controllers, from the hand-held NewStep™ single-axis stepper-motor controller, to the sophisticated and high performance XPS universal controller.

Misumi introduces New Series of Standard Precision Positioning Stages

Schaumburg, IL – Misumi USA, Inc. introduces a new series of Standard Precision Positioning Stages to complement its existing line of High Precision Positioning Stages. The new stages feature a simplified product design that make them suitable and very cost-effective for applications in which frequent and/or fine adjustment is needed, but ultra-high precision is not required.

Misumi’s new series of Standard Precision Stages are designed to deliver optimal adjustment flexibility, with acceptable and repeatable precision levels in positioning devices for automated inspection, assembly, and machining, as well as for processing instruments (e.g., welders) and production jigs. By streamlining functionality and precision levels (relative to straightness, pitching, yawing and rolling), Misumi is able to offer the new models at a price point 20 to 35 percent lower than pricing for its ultra-precise High Precision Stages. Order fulfillment time is also shorter – the new series takes just three days to ship versus six days for High Precision models.

The Standard Precision Positioning Stages series is comprised of three different versions and a total of 22 models. These include:

• Cross-Roller Stages (Part Number XCRS). Available in 9 different models – 3 sizes each in X-Axis, XY-Axis, and Z-Axis versions – these cross-roller guides incorporate two rollers connecting upper and lower plate, resulting in accurate and reliable positioning.

• Dovetail Stages (Rack & Pinion, Part Number XDTS). Available in 9 different models – 3 sizes each in X-Axis, XY-Axis, and Z-Axis versions – this slide mechanism consists of two precision-ground flat surfaces sliding against each other. (Note: Due to direct contact between upper and lower aluminum alloy plates, this stage is not suited for high moment load.)

• Long-Travel Dovetail Stages (Rack & Pinion, Part Number XDTLS). Available in 4 different models – 2 sizes each in X-Axis and Z-Axis – this slide mechanism extends the travel distance of the Dovetail Stage.

All three versions have top and bottom surface plates made of Aluminum Alloy with a Black Anodized surface treatment.

Additional information on Misumi’s standard precision positioning stages, including complete technical data, easy product selection, product options, pricing and delivery times, can be found in the New Standard Precision Positioning Stages Brochure or online at www.misumi-ec.com/eusaen/mech/.
