Sourcing fasteners and standard parts gets easier and faster
Accessing expertise in fastening components and small standard parts can make a machine builder more competitive
EtherCAT sensors enable real-time measurements
Chris Jones, Managing Director at Micro-Epsilon UK, discusses the growing importance of EtherCAT in enabling the latest laser displacement sensors to transfer measurement data in real time in automated industrial environments
Enhanced cycle efficiency thanks to rotary indexing machines
With excellent flexibility, fast setup times and very short non-productive times, rotary indexing machines like the Winema RV 10 Flexmaster are breaking into the domain of cam-controlled machines. Designer Eckhard Neth, Managing Director of Winema Maschinenbau GmbH discusses the road to maximum output
Inverters include energy-saving technology for no extra cost
Optimum efficiency for standard AC asynchronous motors is achieved around full load, and the efficiency falls steeply at partial loads; however, Lenze says that for machinery with substantial load variations, reduced running costs can be achieved by using the company's 8400 series frequency inverters.
Liquid-cooled drives can be an attractive option
Comparatively few specifiers or users of variable speed drives give serious consideration to liquid-cooled products yet, in appropriate applications, they offer many valuable benefits. Stephen Takhar of Vacon explains.
Control for permanent magnet motors
For decades, induction motors have been the first choice for the majority of commercial and industrial applications. Now, however, attention is starting to shift to permanent magnet synchronous motors. But what are the benefits of using these, and how easy are they to control? Stephen Takhar of Vacon UK has the answers.
Fault masking: is your machine as safe as you think?
David Collier of Pilz Automation Technology discusses how fault masking can result in machinery safety systems not being as safe as might be expected, and some alternative solutions to this problem.
Remanufacture option for equipment nearing end of life
Reliable operation of automation equipment nearing the end of its operational life is a high-risk strategy. Reducing productivity and increasing production costs are classic symptoms of this mode of operation for the end-user. What are the answers? Paul Hickman of Bosch Rexroth offers a solution
