Energy efficiency and cost savings in mines and quarries
Most mines and quarries contain a proliferation of electric motors, powering fans, pumps, conveyors, crushers, winches, hydraulic power packs etc. They vary in size and importance from large machines that are critical to site safety and operations to smaller examples that enable basic plant processes such as dust suppression and surface water control. Each one is drawing electricity and unless it is already part of a smart control system, it could be contributing more towards energy and general cost saving.
IT/OT convergence and the end of the automation pyramid
With structures of over four thousand years old, Egypt boasts some the oldest pyramids in existence. The history of automation’s pyramid however, a diagram representing the integration of technologies in industry, dwarfs in comparison. Could this engineering concept be coming to an end? Here, Stefan Reuther Chief Sales Officer at COPA-DATA, explains why IT/OT convergence will lead to the collapse of the automation pyramid.
Innovations in moving-coil actuator technology
In this second technical note on moving-coil actuators, Ed Neff, President of SMAC Moving Coil Actuators (MCA), describes how moving-coil technology is evolving rapidly and offering a competitive alternative to pneumatic drives and moving-magnet rotary motors.
Motor controlers: modification and customisation
Amir Janjua, Technical Engineer at maxon motor UK&I, outlines the options that are available for customers wanting a modified or custom motor controller.
How to select the right stock spring from a range of over 25,000
As market leaders in ex-stock industrial springs, Lee Spring offer some guidance to engineers who are either designing assemblies, developing for production or concerned with installation/maintenance.
The smart, efficient option for driving horizontal conveyors
This technical article explains how Lenze Smart drives for horizontal conveying systems can simultaneously optimise requirements for torque, energy efficiency and starting torque, which is not possible with conventional technologies. Furthermore, the smart drives also reduce the number of variants and engineering effort required in control cabinets and cabling.
How better guard switches improve safety and reduce downtime
Chris Best, Sales Director, and Mabruk Farrah, Managing Director of Mechan Controls, explain the benefits of replacing traditional magnetic reed-type safety switches with coded magnetic, solid-state safety switches, and how easy it is to perform the upgrade.
What is ISO/TS 19837:2018 for trapped key interlocking devices?
'ISO/TS 19837:2018 - Safety of Machinery – Trapped Key Interlocking Devices – Principles for design, selection and configuration' is the first international ISO document devoted specifically to trapped key interlocking and answers many of the questions that arise relating to performance levels, key coding and power interlocking. It is a significant step forward that will provide more choice for users of interlock devices and systems.
