Flexible servo drive system for demanding geared motor applications

Siemens has expanded its extensive drive portfolio for servo applications to include the Simotics S-1FG1 servo geared motors, which are designed for use with the Sinamics S120 drive system. Sinamics S120 drives and Simotics S-1FG1 servo geared motors are an integral component of Siemens Totally Integrated Automation (TIA), which reduces engineering time and costs. The units have electronic rating plates, and the motors are connected via the Drive-Cliq system interface, so the system can be brought online quickly. The engineering of the Simotics S-1FG1 servo geared motor includes high efficiency and low torsional backlash for precise, dynamic motion sequences and is available in the following versions: helical, parallel shaft, bevel and helical worm gearboxes with up to 25 transmission ratios.

Motor Tech: UAV camera stabilization with brushless motors

Today, recon is dominated by unmanned aerial vehicles (UAVs) and drones due largely to concerns for pilots’ safety and costs. However, photos and videos obtained from UAVs are only useful if they are crisp and clear, which requires both precise focusing and extreme stabilization of the camera system. Compact and powerful FAULHABER brushless DC motors from MICROMO were selected to get the job done.

Mobility Tech Ideas: Scissor lift for UTVs

The UTX Scissor lift from Innovative Equipment is designed to be easily fitted and removed from almost any utility vehicle (UTV) in approximately 3 minutes without any heavy lifting. It provides the user with a working height of 18 to 19 ft on nearly any terrain. It can be leveled on slopes up to 12 deg. It has a lifting capacity of 500 to 600 lb and enables users to take a scissor lift "where no scissor lift has gone before." Stability has been tested to five times the ANSI requirements. It also has safety features that will not allow it to be used in unsafe conditions.

Single-rail positioning stage (H-gantry)

H2W Technologies’ latest single-rail positioning stage design is an open-frame XY positioning system. It has two bottom parallel axes with one cross axis connecting the two (H-gantry). Each linear axis uses H2W’s brushless linear motors (BLDM-B04). Each has a total stroke length of 25.67 in. (652 mm) and can generate 6.2 lb (27.8 N) of continuous force and 18.7 lb (83.3 N) of peak force, or a combined 12.4 lb (55.6 N) continuous force and 37.4 lb (166.6 N) peak force on the bottom axis. The non-contact 1-micron resolution encoders allow for precise positioning. The moving tables are guided by a precision recirculating linear ball bearing system. Additional options include a home positioning sensor, end-of-travel-sensors, and custom mounting holes.

Getting a grip on precision: Mechatronics vs. pneumatics

A gripping system for small parts that is both quick and powerful -- until now, that was often only possible with pneumatics. However, recently the leading expert for gripper systems and technology has developed a mechatronics-based EGP 40 gripper that easily achieves the same performance of its pneumatic counterparts. The drive that makes this impressive performance possible is FAULHABER small brushless DC servo motors from MICROMO.

Mini linear motor stage with magnetic direct drive

Motion and nanoposi-tioning industry leader PI expands its PIMag series of high-dynamics linear motor stages with a new compact positioner for automation tasks. The V-408 stage is equipped with an incremental linear encoder for direct position measurement and a high-force 3-phase linear motor drive. The V-408 features high load-capacity precision crossed roller elements with anti-creep cage assist and a zero-wear, non-contact linear motor -- ideal prerequisites for long lifetime in high duty-cycle industrial applications. The high-force linear motor achieves velocities up to 1.5m/sec. An integrated optical linear encoder provides 10-nm resolution. Two models are offered with 25-mm and 50-mm travel range.


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.

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.
