In our earlier article on Mitigating Eddy Current Losses in Rare-earth Permanent Magnets, we explained why eddy currents occur and how they can lead to heat generation and demagnetization in high-speed motors. Building on that foundation, this article introduces one of the most effective engineering solutions for reducing eddy current loss—magnet segmentation. A magnet produced using segmentation technology is often referred to as a laminated magnet, segmented magnet, or sectioned magnet. The concept is straightforward: instead of using a single
