本発明は発電機、電動機等の回転電機の励磁に

法としてのヨーク複合体の製造方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a yoke composite as a method for fixing magnets, particularly ferrite magnets, used for excitation of rotating electric machines such as generators and electric motors.

磁石がはがれるように割れる欠点を有している。 Conventionally, as shown in FIG. 1, a method of fixing to a yoke 1 with an adhesive 2 has been used. In the figure, 3 is a magnet and 4 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, and as a result, their impact resistance has deteriorated (they have become more brittle), and the usage conditions for generators and electric motors have become more severe, making them difficult to use in places with large temperature changes. It has the disadvantage that the magnet will crack when used.
この磁石の割れ、はがれは出力特性を劣化させ
ると共に磁石表面に磁力により付着するためロー
ターとの間にはさまり、発電機、電動機をロツク
させてしまう欠点があつた。 This cracking or peeling of the magnet deteriorates the output characteristics, and since it adheres to the surface of the magnet due to magnetic force, it becomes stuck between the magnet and the rotor, which has the disadvantage of locking up the generator and motor.
本発明は上記欠点を除去し、磁石の割れが発生

A large-diameter flange portion 5a and a small-diameter body portion 5d are integrally formed into a cylindrical shape by extrusion processing or the like from an aluminum plate approximately 0.3 mm thick, and this is inserted into a jig 6. 6a is a center guide, and 6b is a protrusion for angle positioning. Next, as shown in FIG. 3B, this is press-fitted from the small-diameter body into one end of the yoke 1, which is open at both ends, and the flange portion 5a of the magnetic cover 5 is attached to the inner surface of the yoke 1, as shown in FIG. 2A. stick. Next, as shown in FIG. 3C, using a combination jig of jigs 7 and 8 with magnet 3 inserted into jig 8, jig 7 is pulled up, and jig 8 is pushed in from the other end of yoke 1. Then, the magnet 3 is press-fitted between the yoke 1 and the body portion 5d of the magnetic cover 5. Next, as shown in FIG. 3D, the portion of the magnetic cover 5 where the magnet 3 is not inserted is squeezed at four locations in the axial direction using the jig 9, and the body 5d of the magnetic cover 5 is moved radially outward. The magnet 3 is positioned and fixed by being plastically deformed in the direction. As shown in FIG. 2, the ladder portion 5c of 5b is the bottom. If the magnet 3 is to be used under severe conditions, the magnet 3 may be preheated and then the adhesive 2 may be dropped around the magnet 3 to fix it as shown in FIG. 3E.

用でき組付工程を容易確実化する。 According to the present invention, since the inner circumferential surface of the magnet is covered with the cylindrical magnet cover, even if the magnet is chipped or cracked, there is no performance deterioration or inconvenience of inoperation, and the magnet can be removed after fixing the magnet cover to the yoke. Since the magnetic cover between the magnets is fixed by forming a plastically deformed ironing part, there is no need for a positioning jig that is conventionally used until the adhesive hardens, making assembly management easier. Further, even when adhesive is used, since the flange portion of the magnetic cover is press-fitted and fixed, the field function can be reliably performed without the adhesive flowing out. 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. Furthermore, since the magnetic cover is press-fitted from one end of the yoke, which has both ends open, and the magnets are press-fitted from the other end, it is not only possible to assemble it in the axial direction, but also to easily assemble it using an extremely simple jig. Can be done. Although the above embodiment has been described with reference to a magnetic cover made of aluminum, it goes without saying that the magnetic cover may be made of any material, whether magnetic or 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.
