Advanced pneumatic standard cylinders with Adaptive Cushioning System

IMI Norgren’s ISOLine is a true fit-and-forget ISO cylinder. Inside lies the new Adaptive Cushioning System (ACS), which automatically adjusts the cylinder cushioning for changing loads, so manual cushion screw setting is not required. This makes the ISOLine much simpler to install. Other benefits include lower breakaway pressure, lower minimum speed, reduced leakage, polyurethane seals that ensure efficient low-friction operation, and reduced weight (20% lighter than previous versions). All sizes supplied with magnetic piston rod as standard.

ABB's general-purpose motors combine quality, cost efficiency, and industry experience with short lead times

ABB has launched its N-series general-purpose motors to provide a high level of energy efficiency, reliability, and safety in applications where a highly customized motor in the 50- to 8,000-kW power range is not needed. The motors use cost-effective pre-packaged designs to meet the same high quality standards as all ABB motors but with lead times that are several weeks shorter. An easy-to-use online selection tool called "MachSize" simplifies motor configuration. Another tool called "DocStage" is a web-based system for sharing and managing documentation.

Rotate an object to a precise angular position

Goniometer stages can measure angles of objects such as crystals or move an object to a precise angular position along an arc in relation to a fixed point in space. Two goniometer stages mounted in an alpha-beta configuration (stacked) can rotate an object around a fixed point in space on a spherical surface. Optimal Engineering Systems (OES) offers stacked, precision-aligned goniometer stages like the compact AK110-15-10 with a rotation center 50 mm above the upper stage. Goniometers are used for identifying crystals, examining cutting edges of medical instruments, estimating hyperspectral bidirectional reflectance, gloss measurements, measurements of radiation patterns of LEDs, directing lasers, aligning mirrors, and manufacturing quartz oscillator plates using quartz cutting X-rays.

Compact hexapod for industrial alignment applications

PI has added a higher performance model to its range of compact hexapods. The new H-811.i2 provides twice the velocity along with sensor resolution up to eight times higher compared to the current H-811.D2 miniature hexapod. The compact size, robust design with low-friction ballscrews, brushless motors, and powerful controller with multi-axis alignment capabilities make the new hexapod an ideal tool for high duty-cycle alignment applications in optics, automotive, and photonics applications.

Synchronous motors/drives don't need encoder

The SINOCHRON Motor design from ABM DRIVES offers advantages in continuous-duty applications like driving pumps and fans. The efficiency is also better in partially loaded duty cycles when compared to standard asynchronous motors. This motor can replace a stepper motor in some applications. Drive units are virtually loss-free in no-load operation. This motor design also offers advantages in powering conveying equipment, escalators, spooling machines, compressors, and traction drive units. By substituting existing line-powered three-phase drive units, energy savings of 20 to 35 percent can be expected.

Mike Likes: TI doubles power density with motor control

Texas Instruments recently introduced two new device families that help reduce size and weight in motor drive applications. When used together, the brushless DC (BLDC) gate drivers and power blocks require half the board space of competing solutions. An 18-V compact BLDC motor reference design demonstrates how these components can drive 11 W/cm3 power and enable engineers to jump start their designs for smaller, lighter weight power tools, integrated motor modules, drones, and more.

Boeing to modernize, add muscle to next-generation Chinook helicopter

Boeing recently announced it will build and test three U.S. Army CH-47F Block II Chinook helicopters as part of a modernization effort that will likely bring another two decades of work to the company's Philadelphia site.

A $276 million Army contract will fund those helicopters, which will validate technology advancements that will increase the iconic helicopter's lifting power.

"The Army's only heavy-lift helicopter exists to deliver decisive combat power for our ground commanders," said Col. Greg Fortier, U.S. Army project manager for Cargo Helicopters. "The Cargo family is anxious to build upon Col. Rob Barrie's efforts to establish this critical program and deliver an adaptive air vehicle. Increasing payload capacity today enhances battlefield agility and prepares the Chinook for even greater performance gains in the future."

An improved drivetrain will transfer greater power from the engines to the all-new, swept-tip Advanced Chinook Rotor Blades, which have been engineered to lift 1,500 additional pounds on their own. The current configuration of six fuel tanks -- three on each side -- will become two, allowing the aircraft to carry more fuel and shed weight. Additionally, the fuselage's structure will be strengthened in critical areas to allow the aircraft to carry additional payload.

"This latest upgrade for the Chinook fleet is a tribute to the robustness of its original design and exemplifies its 55-year legacy of technological advancements," said Chuck Dabundo, vice president, Cargo Helicopters and program manager, H-47. "The fact that the U.S. Army continues to use and value this platform and they are intending to continue to upgrade it to keep it flying for decades to come is a testament of the capabilities the Chinook team continues to bring."

Boeing will begin building the test aircraft next year. The test program begins in 2019, and first delivery of the Block II Chinook is expected in 2023. Eventually, the Army will upgrade more than 500 Chinooks to Block II configuration.
