March 19, Japan – Denso Corporation announced that it has invested in Next Core Technologies, Inc., headquartered in Uji City, Kyoto, with the aim of jointly developing in the field of motor cores using iron-based amorphous alloys as key materials for reducing power loss in next-generation motor generators for electric vehicles.
Denso said that it has decided to invest in NCT due to its expertise in materials and processing technologies for iron-based amorphous alloys. The two companies will accelerate joint development which aims to establish mass production of highly efficient motor cores by combining NCTs materials and processing technologies for amorphous alloy motor cores with Denso’s expertise in motor generator product development.
As market demand for improved power efficiency in electric vehicles continues to grow, higher efficiency is increasingly required of motor generators, which play a critical role in extending driving range and improving driving performance of electrified vehicles, notes Denso.
The motor core is an iron core inside a motor that conducts magnetic flux. It is manufactured by stacking thin electromagnetic steel sheets and has a significant impact on motor performance, efficiency, and heat generation. Iron-based amorphous alloys are a metallic material with a non-crystalline “amorphous” atomic structure that can enable significant reduction of power loss. However, they are also characterized by hardness and brittleness, making processing and mass production challenging.
Headquartered in Kariya, Japan, Denso supplies advanced technology and components for nearly every vehicle make and model on the road today. It operates about 180 facilities worldwide and has about 158,000 employees. See www.denso.com and www.nextcore.jp.
