News » Technology News Nanotube windings could revolutionise motor designs
Researchers in Finland have built an electric motor that uses a carbon nanotube yarn instead of conventional copper windings. They believe that the development could lead to lightweight motors with much lower losses than traditional designs, which could revolutionise the motor industry.
Real-time technology predicts when cylinders will fail
The US actuator and motion control manufacturer Bimba Manufacturing, has announced a “breakthrough” technology that delivers real-time performance data on pneumatic cylinders, and can predict when a cylinder will fail. Bimba says that it will allow users to users to be proactive about maintaining and optimising their pneumatic systems.
Third-order algorithm optimises multi-axis controls
ACS Motion Control has announced an advanced third-order look-ahead trajectory generation algorithm designed to optimise the efficiency of multi-axis motion control systems. The company says that, compared to second-order systems, the new algorithm will maximise system throughputs by increasing acceleration, smoothness and velocity, while minimising motion-induced vibrations and disturbances.
Robotic fabric combines sensing and actuation
Researchers in the US are developing an elastic fabric embedded with sensors that moves and contracts and could lead to a new class of “soft” robots with sensory skins. The fabric is a cotton material made from a flexible polymer and threadlike strands of a shape-memory alloy that return to a coiled shape when heated, causing the fabric to move.
Robotic ‘cheerleaders’ perform synchronised dances
The Japanese electronics manufacturer Murata has developed a team of tiny robotic “cheerleaders” which perform synchronised “dances” using advanced sensing, communication and group control technologies.
Rare-earth-free motor for dual-clutch systems is ‘world’s first’
The South Korean components manufacturer, LG Innotek, claims to have developed the world's first motor for powering dual-clutch transmission (DCT) systems which contains no rare-earth materials. It is due to enter production next year in Mexico.
Robotic wiring centre will save up to 15 hours per panel
Following five years of development, a German company is about to launch what it describes as “the world’s first robotic wiring centre” for control and switchgear panels. By eliminating the need to wire mounting plates by hand, and by making connections between devices automatically, Kiesling Maschinentechnik says that its Averex machine will cut the time needed to produce a panel by up to 15 hours.
Electrostatic motor ‘out-performs standard designs’
An American start-up company is developing a novel motor technology that harnesses electrostatic forces instead of electromagnetism. Wisconsin-based C-Motive Technologies predicts that its technology could produce the lightest, most reliable, energy and cost-efficient electric motors, and non-contact power transfer devices, on the market. It adds that its C-Machine motors will produce high torque at a lower cost than any other motor available or under development.
Two-armed robot represents 'a new era in automation’
After several appearances of prototypes at trade shows, ABB’s two-armed collaborative robot has been given a name – YuMi – and a launch date – the Hannover Fair next April. ABB says that the robot represents a new era in automation.
Tough engineering plastics are ‘first for 3D printing’
The German engineering plastics specialist igus claims to have developed the world’s first tribo-filament materials for use in 3D printers. It says that the iglidur filaments are up to 50 times more resistant to wear and abrasion than products made from conventional 3D printer materials, such as ABS1 and PLA2.
Ball-shaped gripper adapts to objects with different shapes
A novel balloon-shaped gripper for robots will make its public debut at the International Manufacturing Technology Show (IMTS) in Chicago this month. Unlike conventional grippers, the Versaball, developed by Boston-based Empire Robotics, can grasp a wide variety of objects without reprogramming, and can pick-and-place objects ranging from heavy bricks to delicate light bulbs — all in the same cycle without any changes to the application.
US standards body plans a cyber-security test-bed
The US National Institute of Standards and Technology (NIST) is developing a cyber-security test-bed for industrial control systems. The aim is to measure the performance of industrial control systems when fitted with cyber-security protection in accordance with best practices prescribed by national and international standards and guidelines such as IEC-62443 and NIST-800-82.
Cloud service networks data securely in real time
A Canadian cloud computing specialist, Skkynet Cloud Systems, has launched a cloud-based service that provides remote access to industrial devices and systems without exposing the plants or devices to Internet security risks.
Fourth-gen DTC promises better speed and torque control
ABB has announced a fourth generation of its direct torque control (DTC) motor control platform, with the claim that it will bring more accuracte motor speed and torque control, as well as the ability to control more types of motor.
Stepper motor chip compensates for sudden load increases
The German motion control specialist Trinamic has announced a controller-driver chip for stepper motors that incorporates a new technology that adapts the motor velocity automatically to cope with sudden increases in load. The TMC5062 chip is a monolithic dual-axis motor controller that can deliver up to 1.5A, making it suitable for stepper motors up to Nema size 17, and covering most typical hybrid stepper applications.
