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

September 27, 2022 Editorial Staff Comments Off on 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.  […]
