ドリング５６とバランサー取付突起６２とを形成する。Here, a conventional example will be explained with reference to this publication. In FIGS. 5 and 6, reference numeral 50 denotes a rotor core, which has a hole 51 through which hot water passes during die-casting, and is formed by laminating iron plates. Reference numeral 52 denotes a cylindrical cover, which has a permanent magnet piece 53 fixed to its inside with adhesive and is placed over the rotor core 50. Reference numeral 54 denotes an outer cylindrical shape that covers the outer periphery of the rotor core 50 covered with a cover 52, and an annular space 57 in which end rings 55 and 56 are formed on both sides of this outer cylindrical shape.
．． End ring molds 59 and 60 having 58 are provided. This end ring mold has an annular space of 57.5 mm.
A recess 63.64 is formed which communicates with the balancer mounting protrusion 61.62. When hot water is poured through the hot water tank 65, the hot water first forms the end ring 55 and the balancer mounting protrusion 61 by the end ring mold 59 on the sprue side.
:Form. Next, the rotor core 50 passes through the molten metal passage 51 to reach the end ring mold 60 on the side opposite to the sprue, where also the end ring 56 and the balancer mounting protrusion 62 are formed.

うず電流積の発生は防止される。The hot water also enters the gap 66 between the permanent white stone piece 53 and the rotor core 50. Since the cover 52 and the permanent magnet piece 53 are fixed in advance, almost no hot water can enter between them. A notch 67 is provided on the outer periphery of the rotor core 50, and when hot water is actively passed through the gap 66 between the rotor core 50 and the permanent magnet pieces 53, the permanent magnet pieces 53 are pressed against the cover 52 by the pressure of the hot water, and further Hot water will no longer enter between this cover and the permanent magnet piece. This prevents harmonic secondary copper loss and eddy current product from occurring due to conductive hot water entering between the cover 52 and the permanent magnet piece 53.

くなる問題があった。Pl The problem that the invention aims to solve is,
The permanent magnet piece 53 is pressed against the cover 52 by the hot water that enters the gap 66 between the permanent magnet piece and the rotor core 50, and the hot water does not enter the gap 66 uniformly, deforming the cover 52. The outer periphery of this cover is cut to achieve roundness, but if the wall thickness of the cover 52 is not made thicker, there is a problem that a hole will be formed in this cover during cutting, making it impossible to protect the permanent magnet piece 53.

形される。In the method for manufacturing a rotor configured as described above, to explain the manufacturing process of the rotor 7, first, the laminated rotor core 9 is formed into an outer cylindrical mold 16 with a spacer 15 attached to its surface. It is stored between the end ring gold wheel 19 and 20. When hot water such as aluminum or zinc is poured from the sprue 21, this hot water flows into the annular space 17 formed by the end ring mold 19 on the sprue side to form the end ring 10. Next, the annular space 1 formed by the end ring mold 20 on the side far from the sprue 21 passes through the vertical hole 8 of the rotor core 9.
8 to form an end ring 11. The end ring 10.1'l is integrally formed with a connecting piece 22 formed in the vertical hole 8. After that, the die-cast rotor core 9
is taken out from the casting mold 14, and the spacer 15 is removed and molded.
そして、永久磁石片１２はスペーサ１５の取外された回
転子鉄心９０表面に接着剤で取付けらｎる。Then, the permanent magnet piece 12 is attached with adhesive to the surface of the rotor core 90 from which the spacer 15 has been removed.

が完成する。Finally, the metal tube 13 is attached to the outer periphery of the permanent magnet piece 12 and the end ring 10.11 by shrink fitting, and the rotor T
is completed.

片１２は取付は寸法が（ろうことなく取付けらｎる。Even if hot water enters between the rotor core 9 and the spacer 15 during die-casting, if the surface of the rotor core 9 is cut after the spacer is removed, the permanent magnet piece 12 will not be installed due to the hot water. Can be installed without soldering.
永久磁石片１２は金属管１３を焼バメ固定して回転子鉄
心９に蜜漬して取付けらねでおり、運転時に回転子鉄心
９からズレないようにさしている。The permanent magnet piece 12 is attached to the rotor core 9 by shrink-fitting the metal tube 13 to prevent it from slipping from the rotor core 9 during operation.

いようにしている。The metal tube 13 is shrink-fitted onto the outer periphery of the permanent magnet piece 12 that is attached to the rotor core 9 with good dimensional accuracy, and is twisted to ensure the correct roundness, even if the outer periphery is cut to reduce the wall thickness. This thickness is made uniform, and the thin current product does not increase due to the thick portion of the metal tube 13, so that the performance of the rotor 7 does not vary. Furthermore, by covering the outer periphery of the permanent magnet piece 12 and the end ring 10.11, the metal tube 13 prevents the adhesive that attaches the permanent magnet piece to the rotor core 9 from melting to the outside by refrigerant, oil, etc. I try not to let it out.

もよいことは言うまでもない。In addition, in the above description, the permanent magnet piece 12 is
Although the permanent magnet pieces have been described as being attached to the rotor core 9, it goes without saying that die casting may be performed after attaching the permanent magnet pieces to the rotor core.

The thickness can be made uniformly thin, and variations in rotor performance due to this metal tube can be prevented. Moreover, since the die-casting material does not enter between the metal tube and the permanent magnet piece, the occurrence of harmonic secondary copper loss and eddy current product can be prevented.
