Popularity of permanent magnet motors on the rise
The demands for improved energy savings combined with precision operation has increasingly led engineers to specify permanent magnet synchronous motors (PMSMs), which are more efficient and accurate than an induction motor and a fraction of the cost of a large servomotor. Rick Munz, IHP product manager at Regal, explores this exciting motor option.
Usability and ergonomics of human-machine interfaces
This article discusses the benefits offered by the latest generation of human-machine interfaces (HMIs) thanks to technological developments that have enhanced ergonomics and usability.
Selecting bearings for industrial gearboxes
The requirement to improve the efficiency and performance of mechanical gearboxes has led to more powerful designs which, in turn, require bearings designed to deliver long service life. Understanding the role and design criteria for the different types of bearing within a gearbox is the key to ensuring the correct specification is used when constructing or repairing a gearbox, whatever the size. NSK is now using advanced materials and live predictive models to find the optimum product.
Benefits of Thin Client architectures in manufacturing
Rob Dinsmore, Product Manager for Availability at industrial IT provider SolutionsPT, looks at the benefits of using Thin Client computing within a manufacturing environment.
Glossary of terms: permanent magnet motors
This glossary of terms relating to permanent-magnet electric motor technology has been compiled by Bill Bertram, Managing Director of REGAL C&I Europe.
Why use a retaining compound?
When engineering adhesives are employed in cylindrical assemblies, to bond one part inserted into another, they are known as retaining compounds or retainers. They are commonly used for installing bearings in housings or onto shafts, fixing gears and pulleys onto shafts, retaining cylinder liners, sealing engine and boiler core plugs, fixing oil filler tubes in castings and restoring the accuracy to worn machine tools. In many instances secondary machining operations can be avoided and a more reliable assembly is achieved.
Where will heat treatment be in five years’ time?
The need to develop high-quality, cost-effective products is driving the global heat treating market to grow over 7 per cent, according to a new report on the Global Heat Treating Market 2012-2016, but where will heat treatment be in five years’ time? Kevin Robinson, Business Development Manager at Invensys Eurotherm offers his predictions for an industry undergoing a range of challenges as well as opportunities.
Product recalls emphasise the importance of testing
Despite a multiplicity of tests that manufacturers have to perform on electrical products before they can go on sale, there are always some with defects that slip through the net.
