Luvata Pursues EV Market to Apply Hollow Magnet Wire in Direct Cooled Stators 

Direct-cooled motors with hollow conductor stators offer several advantages over the indirect-cooled motors currently used in EVs, says Luvata of Finland, which has been making copper hollow conductors for more than sixty years. Adoption of the technology, typically used in more exotic applications such as superconduction, high-energy physics and magnetic resonance imaging, into mass-market electric vehicles faces considerable technical obstacles, however, and much higher cost than conventional magnet wire.  […]

Peer into the Future of Magnetics for Energy at ARPA-E Summit 

Magnetics technology plays a key role in much of today’s energy research – looking for breakthroughs in electric propulsion for aviation, high-temperature superconductors, fusion energy, machine modeling for power magnetics, new embedded cooling and winding topologies for improving permanent-magnet motors, even magnetic resonance imaging of crop roots. Visitors to the U.S. Department of Energy’s ARPA-E Energy Innovation Summit & Technology Showcase can explore a fascinating array of these and meet the scientists behind them, as well as many other aspects of energy R&D. It will be held in Denver in May. This article highlights some of the magnetic-related projects. […]
