An Australian company has developed a compact 1MW motor that, it claims, sets new benchmarks for efficiency and power-to-weight ratios. Perth-based HyperPower Technologies developed the 430mm-diameter, 180mm-long motor originally for use in an electrically-powered drag-racing car being developed by a sister company, Top EV Racing, but it believes that the machine could have applications in many other areas including mining, aerospace, light rail and Hyperloop transportation systems.
The German engineering plastics specialist igus has developed an “intelligent” plain bearing that monitors and warns of wear, allowing users to plan their maintenance, repairs and parts replacement activities accordingly. The smart iglidur bearing is intended for use in difficult-to-access bearing points and for applications where no regular maintenance is planned.
The Danish collaborative robot (cobot) specialist Universal Robots (UR) has announced a kit that, it says, will simplify the integration of autonomous bin-picking of parts and accurate placement in machines using its cobots. The ActiNav autonomous bin-picking kit synchronises vision processing, collision-free motion planning, and autonomous real-time robot control, eliminating the complexity and risk usually associated with bin-picking applications.
Engineers in China working for Siemens and the refrigeration and appliance manufacturer, Aucma, have developed an idea for an intelligent disinfection robot into a prototype in just one week. The electrically-powered robot, which can overcome obstacles and navigate slopes, can disinfect an area of up to 36,000m2 in an hour.
A Californian IoT specialist, myDevices, has teamed up with a French electronics developer, éolane, to offer a wireless predictive maintenance system that could help water companies to monitor pumping stations that are increasingly being clogged by the large numbers of people who are flushing disinfectant wipes, paper towels and napkins down their toilets during Coronavirus lockdowns.
Mitsubishi Electric has developed a new technology that integrates power semiconductor devices, passive devices, sensors and other components in the same substrate, and has used the technology build a 100kW (continuous) bidirectional DC-DC converter with a power density of 136kW per litre – making it the world’s most power-dense converter, with a density eight times higher than conventional converters. The company predicts that the technology will result in much smaller power electronics equipment.
By redesigning the internal layout of its micro planetary gearheads, maxon motor says it has been able to boost their efficiencies by around 30%, as well as increasing their torque outputs, improving their feedback, and extending their service lives by up to 11 times compared to some rivals.
At the now-postponed Hannover Fair, Siemens is planning to unveil a concept study that will demonstrate a Sinamics drive system integrated with its Industrial Edge platform. In future, it says, it will be possible to perform high-frequency data exchange in drives using edge devices and to perform complex analyses of drivetrains. The result will be more intelligent drive systems that could lead to new business models.
Researchers at the University of Sheffield in the UK have embarked on a two-year project aimed at developing a novel liquid cooling technology for electrical machines that could cut end-winding temperatures by more than 30°C compared to forced-air-cooled machines with rotor-mounted fans. The technique could boost machine efficiencies and prolong their lives.
At the recent World Economic Forum meeting in Davos, Switzerland, ABB, Ericsson, and the Swiss telecoms company Swisscom, demonstrated real-time 5G communications being used to control robots over a long distance. In the demo, an ABB YuMi collaborative robot (cobot) carved a message in a sandbox that was replicated simultaneously by a second YuMi located 1.5 km away.
Researchers at MIT (the Massachusetts Institute of Technology) in the US have built a soft robotic arm that understands where it is in 3D space using only motion and position data from its own “sensorised” skin.
Wright Electric, the US aircraft developer which is designing an 186-seat all-electric passenger plane, has announced plans to develop a 1.5MW motor and 3kV inverter to power the craft. The UK-based budget airline EasyJet is partnering Wright in the project, which aims to put the plane, called Wright 1, into service from 2030.
SKF has developed what it claims is the world’s first commercial bearing to incorporate a fibre optic sensing technology that can measure loads on the bearing. The components, designed to be used in pumps and compressors, will take the guesswork out of product development, helping to speed up the designs by giving instant access to a variety of data.
The German forklift manufacturer Jungheinrich has a developed a networked machine vision system designed to be integrated into its vehicles' forks to read and compare barcodes on packaging and storage systems, thus avoiding storage and retrieval errors. The company says that the system will prevent items being stored in the wrong compartment, or the wrong pallets being retrieved from a rack.
The German wound components manufacturer REO has developed a more efficient way of winding coils that, it claims, can cut power losses by up to 25%. It also results in components such as chokes and transformers that are smaller and up to 10% lighter than conventional designs.
