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.

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.

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.

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.

Large Hadron Collider restarts after three years of upgrades

Beams of protons are again circulating around the Large Hadron Collider's 27-km ring, marking the end of a multiple-year hiatus for upgrade work.

 

 

The world's largest and most powerful particle accelerator has restarted after a break of more than three years for maintenance, consolidation, and upgrade work at its Geneva, Switzerland, main facility. Two beams of protons circulated in opposite directions around the Large Hadron Collider's (LHC) 27-km ring at their injection energy of 450 billion electronvolts (450 GeV) on April 22.

"These beams circulated at injection energy and contained a relatively small number of protons. High-intensity, high-energy collisions are a couple of months away," says the head of CERN's Beams department, Rhodri Jones. "But first beams represent the successful restart of the accelerator after all the hard work of the long shutdown."

"The machines and facilities underwent major upgrades during the second long shutdown of CERN's accelerator complex," says CERN's director for Accelerators and Technology, Mike Lamont. "The LHC itself has undergone an extensive consolidation program and will now operate at an even higher energy. Thanks to major improvements in the injector complex, it will deliver significantly more data to the upgraded LHC experiments."

Pilot beams circulated in the LHC for a brief period in October 2021. However, the beams that circulated April 22 mark not only the end of the long shutdown for the LHC but also the beginning of preparations for four years of physics-data taking, which is expected to start this summer.

Until then, LHC experts will work around the clock to recommission the machine progressively and safely ramp up the energy and intensity of the beams before delivering collisions to the experiments at a record energy of 13.6 trillion electronvolts (13.6 TeV).

This third run of the LHC, called Run 3, will see the machine's experiments collecting data from collisions not only at a record energy but also in unparalleled numbers. The ATLAS and CMS experiments can each expect to receive more collisions during this physics run than in the two previous physics runs combined, while LHCb, which underwent a complete revamp during the shutdown, can hope to see its collision count increase by a factor of three. Meanwhile, ALICE, a specialized detector for studying heavy-ion collisions, can expect a 50-times increase in the total number of recorded ion collisions, thanks to the recent completion of a major upgrade.

The unprecedented number of collisions will allow international teams of physicists at CERN and across the world to study the Higgs boson in great detail and put the Standard Model of particle physics and its various extensions to the most stringent tests yet.

Other things to look forward to in Run 3 include the operation of two new experiments, FASER and SND@LHC, designed to look for physics beyond the Standard Model; special proton-helium collisions to measure how often the antimatter counterparts of protons are produced in these collisions; and collisions involving oxygen ions that will improve physicists' knowledge of cosmic-ray physics and the quark-gluon plasma, a state of matter that existed shortly after the Big Bang.
