In 2021, the installation of ABB VSDs to improve energy efficiency provided a payback period of three years. This was acceptable as the savings would continue through the life of the installation. However, recent electricity price increases mean that for Severn Trent Water (STW) VSD payback periods tumble. STW is saving 15,000 kWh annually […]
Anglian Water trials using variable speed drives (VSDs) to control the speed of Archimedes screw pumps, resulted in a three-month energy savings of £26,000 across three wastewater treatment sites. It also helped to reduce wear on the associated belts, drive chains and bearings. Each site uses three Archimedes screw pumps each controlled by a 90 […]
When thinking about where your business uses the most energy, it is estimated motor loads consume 60% of electrical energy used in industry. There are many ways to mitigate this, including installing VSDs for general motor loads. Yet, Schneider Electric reminds us that efficient motor management starts with the optimal design of your motor and electrical […]
Around 80 per cent of maximal torque at 90 per cent speed is an efficient duty point for a motor and drive system. However, it is often possible to find a more efficient duty point by exploring a wider range of options. According to ABB, this offers opportunities for a designer tasked with improving the motor […]
In a new whitepaper, ABB reveals the potential for significant energy efficiency improvements in industry and infrastructure enabled by the latest high efficiency drives and motor systems. They call on governments and industry to speed up the adoption of the technology to help combat climate change. According to the International Energy Agency (IEA), industry accounts […]
