<P>PROBLEM TO BE SOLVED: To provide a rotor for a permanent magnetic rotating machine and the permanent magnetic rotating machine having a high output and demagnetization resistance. <P>SOLUTION: Provided is a rotor adapted for a permanent magnetic rotating machine 1 comprising: a rotor 10 and a stator 20. The rotor 10 comprises: 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. The stator 20 comprises: a stator core 21 having a plurality of slots 22; and winding wires 23 wound around the stator core 21. Each of the permanent magnets 12 is in a form of a rectangle with two sides parallel to the radial direction of the rotor on a surface perpendicular to the rotation axis of the rotor 10, and is in a form of a rectangular parallelepiped with four side edges parallel to the axis, and at least one of four angular portions including each of the four side edges of the permanent magnet 12 has stronger coercive force than 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 the rear of the rotor 10 in the rotating direction. Also provided is the permanent magnetic rotating machine comprising the rotor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
