Maintenance: how much is too much? Too little?
Dan Miklovic, a Principal Analyst with LNS Research, discusses how asset performance management (APM) can be used to optimise maintenance intervals, thereby increasing equipment availability and reliability while simultaneously minimising risk and costs.
Efficiency clarifications: motors and VSDs
In 2014, the Department of Energy and Climate Change (DECC) released a preparatory study that identified the environmental improvement potential for products outside the scope of Regulation 640/2009 of the Ecodesign Directive. This study is called Lot 30 and refers to special motors and variable speed drives (VSDs).
Are we ready for a cableless future?
Did you know that until the 1960s, Boeing aircraft manufacturers used ferrets to carry cables to inaccessible areas? The animals were eventually retired because of a tendency to give up their task... or fall asleep. Here Darren Halford, European Automation‘s group sales manager discusses the role of the humble cable in today’s industrial applications.
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.
Online guide to perimeter guarding for robots and robot cells
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.
