Why N42 Magnet can operate well beyond 80°C?

When choosing a magnet for high temperatures, it’s a common mistake to simply rely on the maximum working temperature specified on the neodymium magnet grade data sheet. This only holds true when the length-to-diameter (L/D) ratio is 0.7.

Polar-Anisotropic Ring Magnet

Explaining the benefits and design rules of polar-anisotropic multipole ring magnets can be a bit tedious. To make it easier for you, as an electric motor engineer, I’ve written a brief post listing the key points for quick understanding. Advantages of Polar-Anisotropic Ring Magnets Design Guideline for Engineers We have currently produced polar-anisotropic rings with outer diameters ranging from 4.5 mm to 43 mm. Larger or smaller magnets are not impossible but are waiting to…
