ROTARY ELECTRICAL MACHINE AND VEHICLE |
| 摘要 |
A rotary electrical machine includes a permanent magnet having a composition containing at least one element selected from the group consisting of rare earth elements. A residual magnetization of the permanent magnet is 1.16 T or more. A coercive force Hcj on an M-H curve of the permanent magnet is 1000 kA/m or more. A recoil magnetic permeability on a B-H curve of the permanent magnet is 1.1 or more. |
