Researchers at Tokyo University of Science have developed a computational model that can trace how intricate “maze domain” structures in soft magnetic materials reverse their magnetization—and identify the energy barriers that drive that process. The goal is to...

Fraunhofer IZM has developed a 500-kW inverter that fits in a volume of 1 liter—500 kVA per liter—with peak efficiency exceeding 99%. The unit was built for Mitsubishi Heavy Industries and is designed for 800 V DC drives, delivering 500 A RMS per phase with an...

magniX has launched the magniAIR, an air-cooled electric engine targeting kit planes, light sport aircraft and electric flight trainers. The engine delivers 175 kW at 55 kg—what magniX claims is class-leading power-to-weight for the segment—and is designed to...

Fraunhofer IISB has developed a 750 kW permanent-magnet traction motor for hybrid-electric regional aircraft, hitting 8 kW/kg power density through a combination of thin-lamination electrical steel, hairpin windings and direct oil-spray cooling. The machine...
