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.

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.

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.

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.

Readying the U.S. military for future warfare requires envisioning how next-generation warfighters will maneuver across all domains, including the fundamental land domain.

As a proven leader in ground combat, the Army is accomplishing this task by bringing together ground vehicle experts, industry innovators, and hands-on engineers and researchers to develop, test, and ultimately deliver new fighting vehicles.

Steering the Army's efforts to advance prototypes in this area is the Army Futures Command Next Generation Combat Vehicles Cross-Functional Team, or NGCV CFT, based in Warren, MI.

The NGCV CFT, in partnership with the Combat Capabilities Development Command Ground Vehicle Systems Center, the Program Executive Office - Ground Combat Systems, and industry partners, is working to provide more capable replacements for decades-old combat vehicles and introduce new warfighting capabilities that will produce a speed, range, and reliability of combat vehicles once thought unachievable.

The CFT is also exploring how the Army can strengthen its protection of Soldiers traveling in infantry fighting vehicles and other combat platforms while also ensuring the vehicles are as nimble, durable, and adaptable to unexpected settings as possible.

"Wars are won on the ground. Getting American women and men into positions of relative advantage enables our collective success," said NGCV CFT Director Maj. Gen. Ross Coffman. "The ground manned and unmanned vehicle that Team Detroit delivers will allow the U.S. Army and its partners and allies to maintain dominance over all adversaries far into the future. We cannot expect our foes to capitulate. We must convince them to surrender through materiel, training and leadership."

One of the CFT's top priorities is the establishment of an Optionally Manned Fighting Vehicle, or OMFV, which it is developing through open-source contracts and in-depth conversations with defense industry innovators.

OMFVs, which are presently in a digitally engineered blueprint phase but are set to progress into a prototyping phase in 2023, will not simply serve as a replacement for the Bradley Fighting Vehicle, but instead will bring transformative flexibility and lethality capabilities to future battlefield commanders.

The CFT is also continuing its work on the Armored Multi-Purpose Vehicle, a modern personnel carrier that is undergoing Initial Operational Test and Evaluation, and the Mobile Protected Firepower, a new light tank model that recently completed limited user testing, among other activities.

Along the way, the NGCV CFT is conducting regular Soldier touchpoints and feedback sessions to ensure new vehicle designs meet functional user needs.

As it develops a portfolio of NGCV systems, the CFT is utilizing a Modular Open Systems Approach, standardizing hardware, software, and data interfaces to allow for persistent modernization and smoother, more cost-effective integration of new capabilities moving forward.

Ultimately, "our CFT aims to synchronize efforts between all organizations within the Army Modernization Enterprise to facilitate the rapid acquisition of increased capabilities," said Maj. J. Michael Eisenlohr, Deputy Chief of Staff for the NGCV CFT.

"We are a team of military professionals working with Soldier-centered design leads to develop operationally relevant systems for the future force," Eisenlohr said.
