Permanent Magnet Grades Explained: Why N52 Is Not Always Better Than N35 in Motor Applications
A common misconception in motor design is that higher permanent magnet grades always deliver better performance. This technical guide from HJ Magnets unpacks the three core NdFeB parameters — remanence (Br), coercivity (Hcj) and maximum energy product (BHmax) — and explains why grade selection must be matched to operating temperature, load profile and application environment, not simply maximized.
