出力特性を劣化させてしまう欠点があつた。 Conventionally, a method has been used in which a magnet 3 is fixed within a yoke 1 with an adhesive 2, as shown in FIG.
4 in the figure is an armature. For this reason, since ferrite magnets are hard and brittle, they have the disadvantage that edges and the like may crack during adhesion, assembly, and transportation processes. Furthermore, as magnets have become smaller and more powerful in recent years, they have become more energetic, which has led to a further deterioration in impact resistance, and the use of generators and motors has become more demanding, causing magnets to peel off when used in locations with large temperature changes. This peeling had the disadvantage of deteriorating the output characteristics.
本考案は上記欠点を除去し、磁石の割れを発生

する。 In Figure 3A, the magnetic cover is already
It is formed by extrusion processing or the like from an aluminum plate approximately 0.3 mm thick, and is inserted into the jig 6. 6
a is a center guide, and 6b is a protrusion for angle positioning. Next, this is press-fitted into the yoke 1 as shown in FIG. 3B. Next, as shown in FIG. 3C, using a combination jig of jigs 7 and 8 in which the magnet 3 is inserted into the jig 8, the jig 7 is pulled up, and the jig 8 is pushed in so that the magnet 3 is attached to the yoke 1. and the magnetic cover 5. Next, as shown in FIG. 3D, the magnet 3 is positioned by squeezing four parts of the magnetic cover 5 where the magnet 3 is not inserted. As shown in FIG. 2, 5c is the bottom of the magnetic cover 5 that is continuous with the overhang 5b. Next, after preheating this, as shown in FIG. 3E, adhesive 2 is dropped around the magnet 3 to fix it, and then heated and dried.

する。 According to the present invention, even if the magnet peels off, there is no performance deterioration, assembly management is easy, there is no adhesive dripping, and the field function can be reliably performed. Moreover, not only can the magnetic adhesive be selected from a wide range, but the management of the magnet fixing state can be greatly reduced. In the above embodiment, the magnetic cover made of aluminum was explained, but it goes without saying that the magnetic cover can be made of any material, both magnetic and non-magnetic. . Further, if the bottom part 5c is formed on the magnetic cover, it can be used as a part to be applied to the jig 6 when the magnetic cover 5 and the magnet 3 are press-fitted during assembly, making the assembly process easier and more reliable.

べてが十分満足される。 In the present invention, the thickness of the magnetic cover 3 used is an important point. When using an aluminum plate, if the thickness is too thin, the strength will be weakened, and if it is too thick, the gap between it and the internal armature (usually 0.8 to 1.0 mm is appropriate) will become small. This is because processing becomes difficult. In this sense, in the present invention, in the case of an aluminum plate, it is appropriate that the thickness of the magnetic cover 3 be 0.2 to 0.4 mm. As a result, strength, clearance, and workability are all fully satisfied.
