The permanent magnet 104 is fixed to the rotating body 103 by winding the bind wire 105 having a small diameter. Further, as shown in FIG. 6, in the rotor 111, the permanent magnets 114 which are divided into four in the circumferential direction are located on the outer peripheral surface of the rotating body 113 which is integral with the rotating shaft 112, and the end portions of the adjacent permanent magnets 114 are adjacent to each other. The wedge 115 and the bolt 116
And the permanent magnet 114 is fixed to the rotating body 113. Further, as shown in FIG. 7, in the rotor 121, a permanent magnet 124 divided in two in the circumferential direction is located on the outer peripheral surface of the rotating body 123 which is integral with the rotating shaft 122, and a wide width is provided on the outer peripheral portion of the permanent magnet 124. The non-magnetic metal band 125 is wound and the non-magnetic metal band 125 is pressed by the wedge 126 and the bolt 127 to fix the permanent magnet 124 to the rotating body 123.

り、回転電機１１の性能が低下してしまう。However, the conventional rotor in such a rotary electric machine has various problems. That is, in the rotor 101 shown in FIG. 5, the outer side of the permanent magnet 104 located on the outer peripheral surface of the rotating body 103 is wound by the bind wire 105 to fix the permanent magnet 104 to the rotating body 103. Therefore, this rotor 101 is used as the rotating electric machine 1 described above.
When assembled in No. 1 rotor 1 by the amount of bind wire 105
01 (permanent magnet 104) and the stator core 16 have a large gap, and the performance of the rotary electric machine 11 is deteriorated. Further, in the rotor 121 shown in FIG. 7, the outer side of the permanent magnet 124 located on the outer peripheral surface of the rotating body 123 is wound by the non-magnetic metal band 125, and the permanent magnet 124 is wound.
Is fixed to the rotating body 123, and like the rotor 101, the gap between the rotor 121 and the stator core 16 becomes large, and the performance of the rotary electric machine 11 deteriorates.

4 is fixed to the rotating body 113. In this case, the permanent magnet 114 and the wedge 115, or the permanent magnet 114 and the rotating body 1
13 must be in close contact with each other, and the permanent magnet 1
In order to fix 14 to the rotor 111 without a gap, the bolt 1
When 16 is tightened, cracks may occur in the permanent magnet 114. In addition, the acceleration applied when the rotor 111 rotates is, for example, when the rotor diameter is 0.135.
When the rotation speed is m and the number of rotations is 8500 times / minute, it is 5400G. And the dimensions of the permanent magnet used are 5 mm in thickness and 2 in width.
When the length is 5 mm and the length is 100 mm, the tensile stress of bending generated in the permanent magnet is 73 MPa, which is about the same as the bending strength of the permanent magnet. That is, in the rotor 111, the gap between the rotor and the stator can be made small, but the bending stress of the permanent magnet exceeds the bending strength at high speed rotation, making it unusable for use.

At the outer peripheral surface of the rotating body 133 integrated with the rotating shaft 132, the fitting groove 134 is formed by dividing the fitting groove 134 into four equal parts in the circumferential direction.
34 includes a permanent magnet 135 bonded to an adhesive 136. And, as the same as this rotor 131,
There is one disclosed in JP-A-6-105504. In this configuration, the rotor is configured by performing diffusion bonding on the interface between the two instead of the adhesive 136 and fixing the permanent magnet to the fitting groove of the rotating body.

とし、製造コストが上昇してしまうという問題がある。However, in the above-mentioned rotor 131, the rotating body 133 and the permanent magnet 135 are separated from each other due to the aging of the adhesive 136 and the like. In this case, even if the rotating body 133 and the permanent magnet 135 are separated from each other, the permanent magnet 135 is retained by the wedge action on the inclined side surface portion of the fitting groove 134. However, in this holding state, as with the rotor 111 described above, there is a problem that the bending stress of the permanent magnet exceeds the bending strength at high speed rotation, and the permanent magnet cannot be used. Further, in the rotor disclosed in Japanese Patent Laid-Open No. 6-105504, the diffusion bonding method is used for fixing the rotor and the permanent magnet, and although the bonding strength between both is high, expensive equipment is required. However, there is a problem that the manufacturing cost increases.
