Engineers building linear motion systems can use ground-up DIY approaches or purchase complete turnkey solutions. Here we explain where each tactic is most profitable. By John Brokaw and Kent Martins | Valin Corp. How should designers pick between building linear-motion designs in-house or purchasing pre-engineered assemblies? What is there to consider when determining the best […]
IntelLiDrives high-frequency linear actuators based on voice-coil technology
IntelLiDrives ICVCA circular voice-coil positioning stages are compact stages suitable for closed-loop short stroke positioning applications where precision, repeatability and low force ripple are of utmost importance. ICVCA linear stages are built with precision crossed-roller guides that provide high rigidity to complement the high acceleration capability of the ICVC module at the core of the […]
Can a linear actuator provide the rigidity and accuracy of a linear stage?
Although there are no industry standards that define linear actuators and linear stages, generally accepted terminology indicates that a linear actuator is typically constructed with an aluminum extrusion or base, while a linear stage is typically built on a flat, machined steel or granite base. This distinction implies that linear actuators can typically provide longer […]
ECO series linear stages provide lowest cost of ownership in linear motion
The ECO linear stage series builds upon Aerotech’s long tradition of producing low total cost of ownership motion designs. Excellent positioning specifications, high stiffness, and a variety of options and features combined with economic pricing make ECO stages an ideal choice for applications where robust motion performance is needed. Quality mechanical construction Long-life precision recirculating […]
XY-theta alignment stage from OES with high resolution and repeatability
The XYR-03-01 Alignment Stage from Optimal Engineering Systems Inc. (OES) is a high resolution, high repeatability XY-Theta stage for such applications as angular glass cutting and grinding, wafer alignment, semiconductor handling, laser cutting and drilling. The linear resolution of the X and Y axis is 5 µm (non-micro-step) or 0.125 µm (20 micro-steps per step […]
Belt drives offer practical option for performance designs: Motion Trends report
Belt drives include belts and pulleys (as well as clutches and mechanisms for ratio variation) for power transmission between shafts. In cases where these drives function as a conveyor, the load rides on the belt. Elsewhere (as in actuators or machine-axis coupling) belt drives function as the device to convert rotary motion of an […]
Multi-axis stages and tables: Manufacturer involvement and software yield turnkey motion systems
There’s increasing demand for stages, tables, gantries, and indexing tables with simplicity or turnkey operation — largely because of industry moves toward focused expertise and abstraction. No wonder that motion-system manufacturers are now doing more integration for plant engineers and OEMs. “As we increase our business with OEMs of various markets — including those in […]
High-performance XY stage with linear servo motors from InteLiDrives
New IntelLiDrives XY stage design allows critical elements such as orthogonality, straightness, and flatness to be optimized, resulting in a stage with exceptional geometric tolerances. Direct-drive technology with core-less linear servo motors has no hysteresis or backlash, enabling accurate and repeatable nanometer scale motions in both X and Y directions. Non-contact direct-drive technology offers robust, […]
Robot-transfer unit (RTU) and other linear-transfer system considerations
As robotics applications proliferate, robot integrators have begun to apply more 7th-axis tracks — also called robot-transfer units or RTUs — as well as linear tool-tray transfer systems. Benedict Talan • President | LazerArc of Motion Index Drives Robots excel in repetitive assembly and process operations that include welding, trimming, routing, drilling, fastening, composite layup, […]
Low-profile, high-precision motorized cross-roller linear stages from OES
Optimal Engineering Systems, Inc. (OES) offers a high-precision series of low-cost, low-profile motorized single-axis positioning stages. The compact AQ110 Series of four cross roller linear stages have travel lengths of 15 mm (0.590 in.), 30 mm (1.181 in.), 50 mm (1.968 in.), and 75 mm (2.952 in.) Open-loop repeatability of all stages is 0.5 µm […]
