  • PERMANENT MAGNET, ROTARY ELECTRIC MACHINE, VEHICLE, AND AIRCRAFT
    Publication number: 20230298786
    Abstract: A permanent magnet to be provided to a rotary electric machine. The magnet is expressed by a composition formula: RpFerMsCutCo100-p-r-s-t. R is selected from rare earth elements, M is selected from Ti, Zr, and Hf, p is a number satisfying 10.5?p?12.5 at %, r is a number satisfying 18?r?32 at %, s is a number satisfying 0.88?s?4.5 at %, and t is a number satisfying 0.88?t?13.5 at %. When a proportion rx of Fe to a total sum of Fe and Co is expressed by rx=r/(100?p?s?t), a value r1 of the proportion rx at a center in a q-axis direction of the magnet and a value r2 of the proportion rx at a center in d-axis direction of the magnet satisfy 1.01?r1/r2?2.
