Graphical abstract. Credit: ACS Omega (2022). DOI: 10.1021/acsomega.2c02103 Currently, energy-intensive industries are shifting their production and processes towards more sustainable models. Thus, industrial processes can increase their efficiency while reducing pollutant emissions. Several strategies are being promoted to reach these energy efficiency objectives, such as waste heat recovery, waste stream valorization and electrical flexibility. Looking…

Miniature permanent magnets printed on a 3D printer. Credit: UrFU / Oksana Meleshchuk Scientists from the Ural Federal University and the Ural Branch of the Russian Academy of Sciences are determining the optimal conditions for 3D printing of permanent magnets from hard magnetic compounds based on rare-earth metals. This will make it possible to start…

Buildings consume more energy when empty or partially occupied for extended periods because they are designed to depend on human interactions. Credit: Shutterstock Over the past few decades, the booming global population, growing cities and changing climate have brought global attention to the need to build energy-efficient and sustainable buildings. Evidence suggests that residential energy…

Credit: Pixabay/CC0 Public Domain High-end equipment manufacturing has experienced rapid development in recent years, and the alternating current (AC) motor is indispensable. Traditional control strategies on the motor driving system cannot fully meet the requirements such as strict control accuracy, stable torque and multiple objective optimizations. As the third generation of advanced control technology, predictive…

TQ-230 Permanent Magnet Synchronous Traction Motor and YQ-275 Squirrel-cage Asynchronous Traction Motor.
