| titleOfInvention | Permanent magnets, rotating electrical machines and vehicles |
| abstract | The present invention suppresses a drop in output power in a rotating electric machine that performs variable-speed drive from low-speed rotation to high-speed rotation. The permanent magnet of the present invention has a composition represented by the composition formula: R p Fe q M r Cu t Co 100-p-q-r-t , and has a metallic structure including a main phase and a grain boundary phase, and the main phase has Th 2 Zn 17 -type crystal phase, the grain boundary phase is provided between the crystal grains constituting the main phase. The main phase includes a cellular phase having a Th 2 Zn 17 -type crystal phase, a Cu-rich phase containing Cu at a higher concentration than the cellular phase, and intersecting the c-axis along a section including the c-axis of the Th 2 Zn 17 -type crystal phase A plurality of M-rich lamellar phases extending in the direction of and containing a higher concentration of M elements than the cellular phase. In the cross section, the diameter of the cell phase is more than 200 nm, and the interval between the multiple M-rich flaky phases is less than 80 nm. |
