Tech Tips: Removing the Bottleneck in Welding Electrical Conductors for EVs 

The need to increase the rate of joining electrically conducting components has become critically important in the electric vehicle sector as it is emerging to be the bottleneck of manufacturing, according to Alex O’Farrell, development engineer with Cambridge Vacuum Engineering. As a maker of welding machinery, the UK-based company works close to the subject. In a recent presentation prepared for the 75th International Institute of Welding Annual Assembly & Conference in Tokyo, O’Farrell made his case for electron beam welding technology, highlighted here.

Tech Tips: Understanding the Different Kinds of Magnetic Properties 

Depending on how they interact with magnetic fields, most materials are classified as diamagnetic, paramagnetic, ferromagnetic, ferrimagnetic, or antiferromagnetic. We love the article by Mike Gedeon, customer technical services manager of Materion Performance Alloys and Composites, that explains these different kinds of magnetic properties and related aspects such as magnetic susceptibility. A few highlights follow. […]

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. […]
