０−２８５８４７号公報参照）。2. Description of the Related Art In recent years, a high-speed rotating permanent magnet type rotating machine has been increasingly used. Therefore, various proposals have been made regarding the magnet arrangement for effectively utilizing the rigidity of the rotor that can withstand high-speed rotation and the magnetic flux of the permanent magnet.
For example, as shown in FIG. 8, in the conventional rotor, the rotor core 12 has a structure in which a steel plate of a V-shaped bottom portion and an outer peripheral portion of the permanent magnet 10 are connected to maintain rigidity, and as shown in FIG.
The rotor core 12 of the permanent magnet rotor has a structure in which the gap between the magnetic pole portion 14 and the yoke portion 16 is connected to secure the rigidity of only a part of the lamination number in order to secure the strength, or the outer peripheral portion of the permanent magnet is a steel plate. Are connected to each other. Further, as shown in FIG. 10, a gap portion is provided at the V-shaped bottom portion, and the non-magnetic connecting member 13 is press-fitted into the magnetic pole portion 14 and the yoke portion 16.
A structure having rigidity has been proposed. Regardless of the structure, the steel plate has an integral shape (Japanese Patent Laid-Open No.

漏れ磁束もあった。In the conventional permanent magnet rotor having the above structure, as shown in FIG. 8, a rotor core 12 is provided in a laminated steel plate with a permanent magnet insertion hole 9 and a rotor shaft insertion hole. 11 was punched out, and it was very difficult to take out the permanent magnet 10 once inserted. Also, the leakage flux at the steel plate connecting portion at the V-shaped bottom portion and the steel plate connecting portion on the outer peripheral side of the permanent magnet became large, and the efficiency became poor. In the rotor core of FIG. 9, the magnetic pole coupling portion 15 between the side surface of the permanent magnet 10 and the outer peripheral portion of the rotor core has a narrow portion 15a having a narrow radial width and a wide portion having a wide radial width. 1
5b. However, also in this case, as in FIG. 8, since the integrated structure is such that the permanent magnet insertion hole 9 is punched out of the laminated steel sheet, it is very difficult to take out the permanent magnet 10 once inserted. Further, a gap is provided at the V-shaped bottom to suppress the leakage magnetic flux at the V-shaped bottom, and the magnetic pole portion 14 and the yoke portion 16 are connected by the inner and outer peripheral connecting portions 17 with a part of the laminated steel plate so as to have rigidity. Although the laminated steel plates are fastened at 18, the ratio of the iron core connecting the magnetic pole portion 14 and the yoke portion 16 must be increased in order to maintain the rigidity of the rotor at high speed rotation, and the leakage magnetic flux increases accordingly. I have. Furthermore, there was also leakage magnetic flux at the steel plate connecting portion on the outer shape side of the permanent magnet.

な磁路を確保するのが困難であった。In the conventional permanent magnet rotor shown in FIG. 10, there is a structure in which the divided magnetic pole portion 14 and yoke portion 16 are press-fitted with the non-magnetic connecting member 13 so as to have rigidity. Due to variations in processing accuracy and stacking accuracy, the number of rotations that can withstand the centrifugal force due to the tightening force due to press fitting was limited. Further, in the conventional permanent magnet rotor shown in FIG. 11, since the I-shaped non-magnetic connecting member 13 is press-fitted, the number of processing steps is increased, and the magnetic pole is required to receive centrifugal force in the non-magnetic I-shaped part. A large space is required for the partial cross-sectional area, and it has been difficult to secure an optimal magnetic path.
