Aisin develops an ultra-high-efficiency motor with Tohoku Magnet Institute

Aisin, a Japanese automotive parts company, has jointly developed an ultra-high-efficiency motor with Tohoku Magnet Institute, in which Aisin invested last June.

The ultra-high-efficiency motor is made by processing NANOMET into the core and stator. NANOMET is a nanocrystalline soft magnetic alloy that achieves both high-saturation magnetic flux density and ultra-low iron loss. It was invented at the Institute for Materials Research, Tohoku University and is sold by TMI, a spin-out from Tohoku University. This technology halves the loss compared to traditional EV motors that employ electromagnetic steel plates and improves the vehicle’s electric power efficiency by over 3%, according to the company.

Aisin aims to enhance and test the technology to introduce the motor to the EV market by 2029.
