Researchers at Aichi Steel & Tohoku University Design Lighter, Smaller e-Axle 

Using its molded MagFine alloy, Aichi Steel reports that it has developed in collaboration with Tohoku University an experimental e-axle that is 40% lighter and smaller than conventional designs. It combines a newly developed compact high-speed reducer with a compact and lightweight 34,000 rpm motor. For the first time, says the company, it has succeeded in proofing the technology of a high-speed, high-reduction next-generation electric axle with high-speed rotation and high deceleration that contributes to weight reduction.  […]

Toshiba’s New Magnetic Material Improves Motor Energy Conversion Efficiency

Researchers at Toshiba Corporation have developed a new magnetic material that delivers major improvements in motor efficiency at minimum cost, and with the potential to win significant reductions in power consumption. It has been found to greatly boost motor energy conversion efficiency when it is used as the wedges in the motor, particularly in medium to large induction motors. The material can be installed at minimal cost with no need for design changes. […]
