High-frequency drive users: are you breaking the law?
European Council Resolution (EC) No 428/2009 and its subsequent amendments cover the export of goods, software and technology normally used for civilian purposes but which may have military applications or may contribute to the proliferation of weapons of mass destruction. With this in mind, the EU controls the export, transit and brokering of these 'dual-use' items as a key instrument contributing to international peace and security. This can have implications, for example, for suppliers of high-frequency drives and, importantly, machinery and equipment incorporating those drives.
An introduction to Industry 4.0 for machine builders
This article from Bosch Rexroth introduces the concept of Industry 4.0 and highlights some of the potential benefits that Industry 4.0 offers machine builders and their clients.
Where are the opportunities for torque and linear motors?
According to The World Market for Linear and Torque Motors, a new report from IHS Technology, China leads the global linear and torque motors market, due to continuing growth in the electronics, electronic assembly, semiconductor, machine tools and flat-panel display industries.
Electrically insulated rolling bearings
Electrically insulated rolling bearings feature electrical insulation that is built into the bearing, providing reliable protection against current passage and electrical corrosion. Typical applications are electric motors, generators and other electrical machines. The Austrian manufacturer NKE Austria GmbH offers electrically insulated rolling bearings in several versions. In this article, Klaus Grissenberger, Application Engineer with NKE, explains the causes of passage of electrical current through rolling bearings, damage symptoms and countermeasures, properties and production processes of electrically insulated bearings.

Jeremy Procter, a Member of standards committees ISO/TC 199/WG 6 (Safety distances and ergonomic aspects) and BSI MCE/3 (Safeguarding of machinery), and Managing Director of Procter Machine Guarding, outlines the requirements for guarding robots and robot cells.
Robotics in the fresh produce sector
Chris Sumner, MD of FANUC UK, considers why robotic uptake within the fresh produce segment has been lower than that in other manufacturing sectors.
Pump design and its effect on mine safety and efficiency
The technology involved in coal mining around the world has advanced a great deal over the years, especially in terms of improving the health and safety of the miners. At the same time mining efficiency and production rates have also improved. Pumps, in their many different designs, perform a large number of vital tasks within the mining industry and as such they can be responsible for certain aspects of mine safety. However, with so many pumps in operation they can also make a considerable contribution towards improving the efficiency of the mine, especially in terms of energy consumption.
