Thomson WhisperTrak™ Linear Actuators

Thomson Industries, Inc. introduces the new line of Thomson WhisperTrak™ Electric Linear Actuators.  Through quiet (<45 dBa), maintenance-free operation in a compact one-piece housing, the Thomson WhisperTrak linear actuator maximizes design flexibility and improves performance and user comfort in personal mobility, rehabilitation, and medical equipment applications where reliability, small size and low noise are primary design considerations.  These attributes also make the Thomson WhisperTrak actuator an ideal solution in office and domestic-use equipment.  Thomson WhisperTrak actuators comply with all relevant certificates and are built in accordance with ISO 9000.

A completely sealed, IP67 enclosure enables the WhisperTrak electric linear actuator to provide true maintenance-free operation throughout the entire life of the actuator, even with regular exposure to washdown, rain, dust or other particulates.  Even in these conditions, the WhisperTrak actuator is rated to provide a minimum of 10,000 cycles, defined as one full stroke back and forth, at maximum load.  Reducing the stroke and/or the load will naturally increase operating life.

Thomson WhisperTrak electric linear actuators are available off-the-shelf with optional electronic limit switches (ELS) and anti-rotation options.  These options do not increase the housing size, but fit within the compact envelope of the standard WhisperTrak model.

Thomson WhisperTrak actuators operate at 12 or 24 VDC, and are rated to handle static and dynamic loads up to 2000 N (450 lbs.) at speeds up to 5.8 mm/s (0.23 in/s).  They are available with standard stroke lengths of 10, 20, 30, 40 and 50 cm; custom stroke lengths are available.

Large Aperture Lift Stage from Aerotech

Aerotech’s AVS1000 series stages offer the ideal solution for applications that require positioning of large or heavy loads over very small incremental movements in elevation above a horizontal plane. The low profile and precise motion capability make these stages ideal for use in semiconductor manufacturing and inspection, automated tool alignment, machine vision inspection systems, laser machining applications, and more.

Quality Design Provides Superior Performance
The AVS1000 series provides precise elevation of a load in a vertical plane using a moving-wedge design. The precision machined wedge block converts horizontal movement from a precision-ground ball screw into vertical elevation of the AVS1000 series tabletop. Excellent pitch and yaw characteristics over the length of travel minimize the impact of angular errors. AVS1000 performance includes exceptional resolution (5 nm) and accuracy (±1 µm), with the ability to apply this performance to large loads up to 135 kg.

Sealed linear motion guide bearings with integral wipers are incorporated to provide excellent payload capability, long life, and smooth, precision motion. Stable and parallel vertical motion with no rocking or horizontal deviation of the platform is assured. Careful design of the wedge angle and bearing system allows the AVS1000 series to achieve submicron resolution and still maintain a compact profile.

A Better Approach to Vertical Motion
The vertical lift approach offers an alternative to traditional Z-plane oriented stages. Not only do the AVS1000 series stages offer a lower profile, but the load can also be conveniently accessed from any side due to the large aperture. And by centering the payload over the bearings, there are no cantilevering effects.

Motor and Drives
The AVS1000 series includes Aerotech’s high performance NEMA 34 frame-size BMS series brushless, slotless servomotor. The slotless motor has zero cogging and therefore is optimized for applications requiring very smooth motion.

HepcoMotion® ALR Aluminum Rings from Bishop-Wisecarver

Bishop-Wisecarver Corporation announces the availability of the new HepcoMotion® ALR Aluminum Ring, a cost-effective rotary movement system for medium precision and light load applications. ALR is suitable for use in applications requiring corrosion resistance and a non-magnetic environment.

Available with external vees and in 4 sizes from 148mm to 300mm in diameter as standard, ALR Rings are machined from high strength aluminum alloy and are anodized for excellent durability with an attractive finish. A number of special rings are also possible, such as additional diameters and thicknesses, rings with internal vees, gearcut rings, and rings machined in the form of self aligning timing belt pulleys.

Matched to run perfectly on the surface of the Aluminum Rings are Bishop-Wisecarver’s Size 2 DualVee® polymer overmolded guide wheels with integral studs. The outer portion of the polymer wheels are comprised of a high performance plastic molded onto a stainless steel bearing and stud which allows for smooth, anti-friction motion and little wear on the aluminum ring vees. For smaller, lighter applications, Bishop-Wisecarver’s Size 1 and Size 0 polymer wheels can also be specified.

Haydon unveils new linear actuators

Haydon Kerk Motion Solutions (www.haydonkerk.com) has proudly released an exceptional line of hybrid stepper motor linear actuators that offer new avenues for equipment designers who require exceptional endurance and high performance in a small package. Its numerous patent pending designs utilize a proprietary manufacturing process, which integrates engineering thermoplastics in the stainless steel acme lead screw and the rotor drive nut. This enables the linear actuator to be more durable, more efficient and much quieter than the bronze nut and v-thread configuration generally used in other linear actuators. Motor life is enhanced more than 10 times compared to the traditional bronze nut style – and it does not affect the cost and requires no maintenance. It also features a bearing pre-load adjustment that does not protrude from the motor configuration usually used in other actuators.

Haydon’s hybrid linear actuators consist of six sizes, from 21 to 87 mm square corresponding to NEMA size 11, 8, 17, 14, 34 and 23. Each size comes in three designs – non-captive, captive and an external linear version. There are more than 20 different travels per step available, from .001524 mm (.00006 inch) to .127 mm (.005 inch). It also allows micro stepping to achieve even finer resolution.

Haydon’s linear actuators are suitable for applications that require a combination of rapid motion, long life and precise positioning. Typical applications include X-Y tables, semiconductor handling, medical equipment, valve control, telecommunications equipment and numerous other uses.
