Daido Steel Co., Ltd. and NHK Spring Co., Ltd. (Nippatsu) have jointly developed next-generation motor rotors for electric vehicles (EVs) that achieve higher output and improved recyclability. Utilizing Daido's heavy-rare-earth-free hot-deformed magnets, the new rotors offer greater design flexibility compared to conventional sintered magnets. The development includes a high-output SPM rotor reinforced with CFRP and an easy-to-dismantle IPM rotor that uses leaf springs instead of resin, significantly reducing CO2 emissions during recycling. Promotions will begin in May 2026, with exhibitions scheduled in Yokohama and Nagoya.
