Linear robots are now even more versatile

Bosch Rexroth has expanded its portfolio of linear robots (eight different axis combinations with 68 sizes!) for various applications in factory automation. The much wider range of working areas and loads makes the Cartesian subsystems also suitable for applications like battery handling or intralogistics. Predefined axis combinations make for quick and easy sizing and selection. Configure and finalize online and order as preassembled subsystems -- optionally with controllers. Each multi-axis system is also available as a Smart Function Kit for handling or dispensing. Preinstalled software allows for fast commissioning and intuitive programming.

New mini planetary gearmotors

New PH Series Mini Planetary Gearmotors from Applied Motion Products are used with small step motors in NEMA 8, 11, and 14 frame sizes. These gearmotors are used in applications where space is critical. Small motors usually don't produce enough torque for demanding applications. Mini Planetary Gearmotors are an ideal solution. They offer an increase in torque and better inertia matching without breaking the budget.

Robots handle post processing for metal AM parts and components

The NetShape Robot from Rivelin Robotics provides an automated solution for metal support removal and targeted finishing to meet the standards of mission-critical industries. Driven by the powerful NetShape control software, both machine learning and traditional deterministic control theory are used to optimize the quality and repeatability of the work. The result is an automated support-removal solution that reduces defects by 90%, exhibits a 10-fold reduction in operational costs, and eliminates human risk and variability.

Flat external rotor with encoder

The DF45 brushless DC motors from Nanotec are now available with an integrated encoder. The new flat motors with a diameter of only 45 mm are ideal for applications that require precise positioning in confined spaces such as AGV wheel drives, access control systems, and door drives. The two-channel encoder has a resolution of 1,024 CPR and provides additional Hall signals for commutation. The difference in length between the standard motor and the encoder version is only 2 mm, as the encoder has been completely integrated. The DF45-E has a rated power of 65 W at a rated speed of 4,840 rpm. Custom windings or shafts are also available.

The influence of operating speed on step motor selection

According to the engineers at Lin Engineering, "Frequently, when it comes to step motor selection, users will select a motor with the highest holding torque rating, assuming that it will give them optimal performance. However, it is an improper practice to select a motor based on holding torque alone. In fact, the step motor with the highest holding torque in many situations can prove to be a poor choice -- especially when trying to maximize torque at a desired operating speed."

Extra-Duty Overhung Load Adaptors

Zero-Max has announced three entirely new Extra-Duty Overhung Load Adaptor (OHLA) models (350, 650, 950). The new designs feature a number of carefully chosen upgrades including spherical bearings, enhanced sealing technology, stronger shafts, and a longer profile delivering increased operating life, heavy load capacities, and higher speed ratings. They provide a solid, permanent mounting surface, eliminating premature motor or pump failure due to axial and radial overhung loads on a motor or pump shaft.

Heavy duty: Electric actuators open 3-ton bunker doors

Converting a 1960s nuclear-proof bunker into a museum is full of challenges, one of which was to repurpose 3-ton, all-metal nuclear-safe doors as fire doors. But how do you open and close such massive doors safely? Luckily, Thomson Industries' Electrak HD electric linear actuators were up for the challenge.

Complete factory automation solutions from Bosch Rexroth

Bosch Rexroth is showcasing complete factory automation solutions that boost consumer packaged goods (CPG) productivity at PACK EXPO INTERNATIONAL 2022 this week (Oct. 23-26). Demonstrations include open control systems, plug-and-play smart mechatronics, autonomous mobile robots, cobots, flexible conveyors, and more. The main focal point is a live multi-tech demo that integrates several automation technologies: a lightweight, maneuverable Kassow Robot picks up product from a moving VarioFlow plus conveyor to place it on a pallet, and when the pallet is full Rexroth's MP1000R AMR moves the product to a storage location using Rexroth's ROKIT Locator software.

Why are there different servo drive form factors?

Servo drives come in all shapes and sizes -- just ask the engineers over at Advanced Motion Controls. Oftentimes, a key part of deciding which servo drive to use for your application is deciding which form factor to use, which raises the question: What exactly is a form factor, and why are there so many of them? Learn about types, benefits, and applications.

Dumb missiles get smart: APKWS guidance kits went three for three against armored targets

BAE Systems says it has successfully tested its plug-and-play APKWS (Advanced Precision Kill Weapon System) laser-guidance kits with High-Explosive Anti-Tank Anti-Personnel Anti-Materiel (HEAT/APAM) warheads from General Dynamics Ordnance and Tactical Systems.

Guided by APKWS kits, which transform unguided rockets into smart munitions for precision strikes on soft targets, equipment, and armored targets, the rockets went three for three against armored targets, demonstrating their versatility to engage a broad set of targets and enable new missions for warfighters.

During a recent test event, BAE Systems launched rockets with HEAT/APAM warheads and APKWS guidance kits against well-armored targets -- including a steel plate and an armored military vehicle. All test shots were direct hits, defeating fortified targets at range. The HEAT/APAM warheads are capable of penetrating thick armor, which improves the versatility of rockets guided by APKWS guidance kits.

APKWS requires no modifications to the standard rocket motor, firing platform, or fire control system. BAE says its APKWS kits have "achieved over a 93 percent hit rate when fired from rotary- and fixed-wing platforms" in total, with "17 of the world's most utilized rotary- and fixed-wing launch platforms qualified" to use the system (such as the AH-64 Apache and F-16 Fighting Falcon), which is designed to lock onto targets up to 3 km away.

"APKWS guidance kits with HEAT/APAM warheads provide a low-cost, lightweight, easy-to-deploy strike capability against armored and unarmored targets," said Sam Kirsh, APKWS program manager at BAE Systems.

The APKWS mid-body guidance and control section is also compatible with existing and new inventories of Hydra 2.75-in. (70-mm) rocket motors, warheads, and launchers. It simply inserts between the rocket motor and warhead for easy installation on a variety of platforms. The munitions require minimal training to assemble and fire, and can be fired from a variety of launch platforms, including fighter jets, combat helicopters, ground vehicles, and remote weapon stations.

APKWS guidance kits have also proven their accuracy in combat with hundreds of successful shots fired with the M151 high-explosive warhead.
