ABB is working with Boliden, the Swedish mining and smelting company, to build a strategic cooperation to use low carbon footprint copper in its electromagnetic stirring equipment and high-efficiency electric motors. The aim is to reduce greenhouse gas emissions while driving the transition to a more circular economy. […]
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.
