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. […]
