PROBLEM TO BE SOLVED: To provide a rotor for a permanent magnetic rotating machine and the permanent magnetic rotating machine having high output and demagnetization resistance.SOLUTION: A rotor used for a permanent magnetic rotating machine 1 comprises: a rotor 10 comprising a rotor core 11, and a plurality of permanent magnets 12 embedded in each of a plurality of insertion holes formed in the rotor core 11; and a stator 20 comprising a stator core 21 having a plurality of slots 22, and winding wire 23 wound around the stator core 21. The permanent magnets 12 are in a form of a rectangular parallelepiped with two sides parallel to a radial direction of the rotor on a surface perpendicular to a rotation axis of the rotor 10, and is in a form of a rectangular having four side edges parallel to an axis direction, and at least one angular portion of four angular portions including each side edge of the four side edges of the permanent magnet 12 has stronger coercive force than that of a center inside the rectangular parallelepiped, and is placed in the insertion hole such that the angular portion is on a stator side and in a rear of the rotor 10 in a rotating direction. Also provided is the permanent magnetic rotating machine comprising the rotor. |
