Title: ROTATING ELECTRIC MACHINE AND VEHICLE
Abstract:
A rotating electric machine of an embodiment has a shaft, a rotor iron core, and a plurality of permanent magnets. The shaft rotates about the axial center. The rotor iron core is connected to the shaft. The plurality of permanent magnets are provided in the rotor iron core and include at least a first permanent magnet and a second permanent magnet. The first permanent magnet has an intrinsic coercive force of 1200 [kA/m] or more. The second permanent magnet has an intrinsic coercive force of 800 [kA/m] or more and has a remanent magnetization that is substantially the same as or larger than that of the first permanent magnet and a recoil permeability that is smaller than that of the first permanent magnet.
