Tech Tips: Bakker Magnetics – Improving Energy Density of Permanent Magnets for e-Mobility Manufacturing

November 16, 2021 Editorial Staff Comments Off on Tech Tips: Bakker Magnetics – Improving Energy Density of Permanent Magnets for e-Mobility Manufacturing

Permanent magnets (PM) are the heart of the drive systems used in the e-Mobility industry. The stronger the magnet is, the higher the higher the motor’s output and the smaller and lighter the motor can be built. But a powerful magnet must also be able to resist demagnetization by heat or a magnetic opposite field. The Dutch company Bakker Magnetics uses two new techniques with which permanent magnets can be produced even stronger and more robust: Grain Boundary Diffusion (GBD) and Grain Refining Technology (GRT). Major advantage: less Heavy Rare Earth Elements (HREE) are used. […]

Toshiba’s New Magnetic Material Improves Motor Energy Conversion Efficiency

June 9, 2021 Editorial Staff Comments Off on 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. […]
