A Japanese startup has developed a motor for electric vehicles that requires no rare-earth elements.
                
The global auto industry is keen to substitute rare earths. Most of the materials are supplied by China, whose exports could be disrupted by a future trade war under President-elect Donald Trump.
                
The venture, Next Core Technologies, showed off its motor at CES, one of the world&#039;s largest tech fairs, held earlier this month in Las Vegas. It drew plenty of interest from visitors.
                
The prototype contains no terbium or dysprosium. These elements are used in high-performance EV motors to prevent them from over-heating.
                
Next Core Technologies says it applied its own metal refining and processing skills for heat-resistance.
                
The Kyoto-based venture also says the motor uses far less electricity than conventional types. Yamamoto Yuki, Next Core Technologies&#039; chief executive officer, said, &quot;Regarding the conflict between the US and China, we can&#039;t deny the possibility that it could affect motors, rare earth materials and other items. So I can see more active moves to produce products domestically without reliance on imported materials.&quot;
                
Orders for the prototype are flooding in from automakers in Japan, Europe and the United States.
