Brushless slotted flat motor weighs only 15 grams

The 20ECF brushless slotted flat motor is the latest motor to join Portescap's flat motor line. The motor's 19-mm rotor diameter is notably smaller than the 20-mm diameter of competitive solutions. At 15 grams, the 20ECF provides a mass savings of at least 30% when compared to competing motion solutions. The motor's design optimization also helps it achieve a 50% improved motor regulation factor relative to standard available solutions. Applications include surgical and service robotics, lab automation, premium tattoo machines, electric grippers, LiDar, and pumps.

Efficient, reliable and flexible robot gripper optimizes machine tending operations

To continuously deliver high-quality results to its customers, WEFAG AG not only invested in new CNC machines, but also deployed a collaborative application with the 3FG15 gripper from OnRobot to tend the CNC machines. This makes it possible for the Swiss family-owned company to meet extremely short delivery times and smaller batch sizes confidently, while also reducing the workload of employees, who can now focus on more demanding tasks.
Watch how the 3FG15 delivered an ROI in 2 months.

Differences between types of multi-axis positioning stages -- parallel vs. stacked

According to the experts at PI (Physik Instrumente), stacking individual motorized stages is a fine approach for assemblies of just a few axes, but as applications become more complex a 6-axis stage design based on parallel kinematics could be the best option. Learn about stiffness, inconsistent dynamics, size and weight fragility, and even cabling considerations for multi-axis applications. Lots of good info here.

What are Crossed Roller Bearings?

Learn all about HIWIN Crossed Roller Bearings that are three to four times more rigid than standard bearing solutions and are capable of handling loads in the axial, radial, and moment directions. They consist of an outer ring, an inner ring, and a plurality of rollers and spacers. The roller lies between the inner and outer ring with the spacers placed between the rollers to prevent the mutual friction between them, thereby decreasing the torque resistance for rotation. Many options are available depending on the level of rigidity needed.

Compact electrically controlled hydraulic actuator

Bosch Rexroth has expanded its range of standardized self-contained actuators by adding the CytroMotion system solution. With the help of the new compact actuator, linear movements involving forces up to 110 kN can be achieved in a range of machines and systems in smaller spaces -- more efficiently and more sustainably. These benefits can be seen over the entire life cycle. Thanks to fully electric control, CytroMotion makes engineering and commissioning easier. The efficient, power-on-demand drive and the maintenance-free, hermetically sealed design also minimize operating costs.

Belt-driven actuators for harsh environments

Rollon's newly enhanced Plus System lineup of belt-driven linear actuators can be integrated seamlessly with industrial machines. Combining sturdy construction, protective features (sealed), and high-performance characteristics for load, moment control, speed, and acceleration, the Plus System family features an anodized aluminum structure and steel reinforced driving belt. Three types available: Plus System ELM completely enclosed unit, Plus System ROBOT for multi-axis or SCARA robots, and Plus System SC for vertical motion in gantry applications.

Linear positioning and motion systems at IMTS 2022

SCHNEE-BERGER Linear Technology will spotlight its precision positioning and motion systems at IMTS 2022 in September. On display will be a fully functioning demo of a complete linear motion technology system featuring the company's leading and most innovative linear motion components. When linear tech components are designed to work together to create the most effective solution for machine movement, OEMs can accelerate design and manufacturing, reduce assembly time and labor, and achieve a lower TCO.

Micro-sized FlexPro servo drive

ADVANCED Motion Controls' new 60-A continuous FlexPro servo drive model FM060-60C-RM is the third "machine embedded" version in this power range, adding RS-485/232 communication to the previously released EtherCAT and CANopen versions. This drive can operate at its 60-A peak rating continuously with no need for current foldback -- impressive because the micro-package size means up to four units can fit within the footprint of a business card. Applications include cobots, AMRs, AGVs, portable devices, lab and warehouse automation, military equipment, and more.

NSK's new Active Casters help robots move effortlessly

NSK has developed new Active Caster technology for service robots and mobility drive applications. The compact, electric-powered turning unit provides both drive and steering functions based on the difference in rotation between two motors. The developers say it generates less vibration compared to an omnidirectional mobility unit using Mecanum wheels.

Machine learning eliminates cogging for linear motors

The highly dynamic AL8000 linear motors from Beckhoff now meet even greater requirements for accuracy and synchronization with the new TwinCAT Cogging Compensation software, which compensates for cogging forces. Cogging forces in linear motors are caused by the magnetic attraction between the iron core in the primary part and the permanent magnets in the secondary part. AL8000 linear motors are particularly suitable for high-precision applications such as milling machines or laser cutting machines.

U.S. National Reconnaissance Office looks for more commercial services: radar, imagery, launch

By C. Todd Lopez, U.S. Department of Defense

In May, the National Reconnaissance Office (NRO) announced the award of three contracts to private-sector companies for commercial imagery. It's something the agency would like to do more of, said its director.

"Certainly, we are looking for more commercial services, Chris Scolese said, during a discussion Aug. 4 with the Mitchell Institute for Aerospace Studies. "We kind of have a motto of 'buy what we can, build what we must.' But really what it comes down to is the commercial market has really grown. And we're seeing a lot of capability out there that the commercial companies are providing."

Looking to the private sector to provide satellite imagery, he said, can be less costly but equally valuable than what the NRO might do with its own assets, Scolese said. It also means the NRO can direct resources toward intelligence gathering that's important to the warfighter but has no commercial value.

"It ... allows us to focus on those things ... that are critically important that have either no commercial value at all, but have incredible intelligence value, that we need to go off and do," he said. "And oftentimes, those are extremely complex systems that would be very expensive to develop and therefore ... the lack of commercial interest in them."

Right now, Scolese said, NRO's relationships with the three companies it signed to contracts in May are going well. But he said the NRO is looking forward to bringing in new entrants and new capabilities, and that the agency has a plan for that.

"About yearly we're going to ... go off and ask for commercial companies to come in with their ideas so that we can engage early, prior to having to award of contract, so they can understand what the government's needs are and we can understand what their capabilities are," he said. "When it comes time to go off and have a contract like we have for electro-optical imagery, for radar, they'll be ready and we'll be ready."

Commercial imagery isn't the only place NRO has opted to work with partners. Launch is another such area. The U.S. continues to launch capabilities into space from both the Eastern and Western Ranges, which include locations such as Cape Canaveral Space Force Station and Kennedy Space Center in Florida, and Vandenberg Space Force Base in California.

But the NRO has also now partnered with New Zealand to launch smaller assets into space and will soon work with the U.K. on air-launching assets as well. Scolese said it gives his agency more flexibility as it tries to proliferate the number of assets it has in orbit.

"Having the capability to launch pretty much from almost anywhere in the world gives us great flexibility," he said. "It adds to our resilience, because we're not relying on just one or two launch bases. It allows us to reconstitute if we want to do that. It gives us a greater flexibility because we now have the opportunity to sort of pick launch bases."

Also, he said, launching from locations like New Zealand or the U.K. has another added benefit as well.

"I think it sends a message to the world that we really value our partnerships with our international communities," he said.
