Successful trials at three Anglian Water sites prove variable speed drives can cut the energy used by Archimedes’ screws.

Whether you are looking to replace or repair a motor, it is important to give accurate details of the motor you currently have. The most relevant information should be recorded on the motor's nameplate. Karl Metcalfe explains what the key elements mean.

WEG has released a free whitepaper including architecture design examples for implementing VSDs in different safety systems. 

Anders Nazell explains how it is possible to contribute to an even greener future for the pulp and paper industry, by making small equipment upgrades.

Through a combination of standard industrial motors and creative collaboration, advanced technology customisations are made to allow high-precision, long-life motors to make it to Mars and beyond.

Brushless DC motors are the technology of choice for applications operating at higher speeds. However two different motor architectures can present a selection conundrum, says Madhavan Ramanujam and Cyril Baud.

A new approach to smart condition monitoring allows much more than just monitoring machines and processes – it provides extensive information about the ‘state of health’ of machines and plants without the need for any additional, costly sensor technology, says Marc Vissers. 

Interestingly, there are some operating conditions where servomotors that should be big enough for an application are actually too small, in terms of their power rating. Find out more. 

Control Engineering Europe finds out how a traditional mains-driven geared motor can be integrated into the IIoT without the need for a frequency inverter.

Tea manufacturers in Sri Lanka have benefitted from both energy reductions and increased product quality since the adoption of variable frequency drives into the leaf drying process.

Paul Streatfield explores the most recent criteria for industrial drive specification, which helps machine builders meet the challenges posed by today’s industrial requirements.

Configuration using PC-based control software, EtherCAT networks, integrated drives, and one-cable technology (OCT) can simplify motion control system design and reduce servomotor costs, says Matt Prellwitz.

Franck Roussillon offers some advice on how to match the most suitable air motor to an application.

The main hoist of a crane vessel capable of lifting more than 80 tonnes of load can now operate more precisely and accurately following the installation and commissioning of a heavy-duty Optidrive P2 variable frequency drive from Invertek Drives.

Control Engineering Europe finds out more about a new approach to energy efficiency and system cost optimisation through the use of a DC grid.

Control Engineering UK finds out more about the factors that have a role to play in DC motor failure.

The drive towards energy efficiency is not as straightforward as it might appear and it is important to recognise and overcome any barriers to reap the benefits, says Heikki Kervinen.

Andrew Fallows considers this frequently asked question on the issue of speed control and offers some advice to engineers.

Brian Bannister argues that it is better for OEMs to build in compliance to electric motor energy efficiency requirements now, to avoid the need for future product redesigns, and to provide customers with immediate energy saving benefits.

Mike Lomax examines the role of intelligent drive systems in optimising machine configuration and performance and aiding the adoption of Industry 4.0.
