る。[Prior Art and Problems to be Solved by the Invention] Generally, this type of permanent magnet rotating machine is equipped with a magnet for exciting the rotor. Since the magnet itself is directly exposed as it is fixed in place by a means of fixation, it is difficult to assemble the permanent magnet rotating machine, especially in the case of high-performance ferrite magnets used in recent years, which are brittle. This is not a fake, which often causes damage due to the edges of the magnet being chipped, but it is also inferior in strength, and the magnet may break or peel off due to slight shocks or temperature changes during use. This has caused problems, such as the output characteristics being degraded due to damage, and damaged magnets becoming trapped between the rotors, preventing the rotor from rotating, making it no longer usable as a permanent magnet rotating machine. was. Therefore, the applicant of the present application has proposed Japanese Patent Application No. 54-60375 and Japanese Patent Application No. 1387-1987, in which a magnetic cover is provided on the inner peripheral surface of the magnet.
No. 58, etc., we devised a completely new permanent magnet rotating machine that can eliminate all the drawbacks of the conventional permanent magnet rotating machine, but the present invention further improves these and creates a more excellent permanent magnet. The purpose is to provide rotating machines.

However, in addition, a bottom portion 4 is formed on the press-fitting start end side of the magnet cover 4 via an inclined tapered surface 4a.
b is formed. This tapered surface 4a comes into contact with the inner peripheral edge of the magnet 2 when the magnet cover 4 is press-fitted, as will be described later. In addition, the press-fit end side of the magnet cover 4 is bent outward in an L-shape in cross-sectional view, and comes into contact with the top surface of the magnet 2 and the inner peripheral surface of the yoke 1 when the magnet cover 4 is press-fitted.

れることとなる。At this time, in this embodiment, the side opposite to the boss portion of the magnet 2 (
(lower side) is held down by the holding jig 5 to prevent it from shifting. Thereafter, the magnet cover 4 is press-fitted from above using the press-fitting jig 6. In this case, in the present invention, the outer diameter A of the magnet cover 4 is larger than the inner diameter B on the inner peripheral surface of the magnet 2 (outer diameter). Since the diameter A>inner diameter B), as the magnet cover 4 is press-fitted, the magnet cover 4 will closely deform inward along the inner peripheral surface of the magnet 2 at the corresponding part of the magnet 2. . As a result, the magnet cover 4 has a small diameter corresponding to the inner diameter B of the magnet 2, and the gap between the magnets 2 and the vicinity of the edge of the magnet 2 is adjusted to suit the deformation of the magnet cover 4. Although the magnet 2 is deformed, the magnet 2 is in an overhanging state while maintaining a substantially large diameter state, and the magnet 2 is directed toward the inner circumferential surface of the yoke 1 while completely preventing displacement around the axis of the yoke 1. It is firmly clamped and fixed by pressing it.

て、磁石２部位は小径で。As described above, in the present invention, the magnetic cover 4 is simply press-fitted into the temporarily fixed yoke 1 in which the magnet 2 is positioned and held, which is an extremely simple operation, and the magnet 2 portion has a small diameter.

せて作業工程の簡略化を計ることができるものである。The gap between the magnets 2 can be made of a large-diameter concave-convex shaped magnetic force bar 4, which can firmly clamp and fix the magnet 2. Therefore, the gap between the magnets 2 can be made of a large-diameter concave-convex shaped magnetic force bar 4, so that the magnet 2 can be firmly clamped and fixed. As in the case of inserting the magnet cover 4 into the yoke 1, it is possible to completely eliminate the work process of tightening the magnetic cover in the gap between the magnets 2 using an appropriate jig to increase the diameter one by one, and avoid over-straining. In addition, it is possible to reliably eliminate inconveniences such as a decrease in the strength of the magnetic cover 4 and the occurrence of cracks caused by the magnetic cover 4, and it is also possible to simplify the work process while significantly improving work efficiency.

である。In the yoke 1 formed in this manner, the magnets 2 are covered by the magnet cover 4 and are not exposed. Therefore, when the rotor is inserted, the edges of the magnets 2 may be chipped or the magnets 2 may be damaged due to impact or the like. There is no inconvenience such as peeling off, and it can be used as an ideal permanent magnet rotating machine. Furthermore, since the magnet cover 4 does not require processing such as forced ironing, it is also strong in terms of strength. Therefore, it is not only possible to increase the strength of the permanent magnet rotating machine, but also to make it possible to set the thickness of the magnet cover 4 thin.

ごき力を弱いものとすることができる。It should be noted that the present invention is of course not limited to the above-mentioned embodiments, and the point is that the outer diameter of the magnet cover press-fitted into the yoke may be larger than the inner peripheral surface of the magnet. Moreover, the material of the magnet cover is not only aluminum, but also magnetic and non-magnetic metals such as zinc and iron.
Materials such as plastics may be used as long as the strength is satisfied, and it is sufficient for the magnet cover to deform along the inner circumferential surface of the magnet during press-fitting. Thickness, size of yoke and magnet,
Alternatively, it can be freely determined depending on conditions such as the number of magnets.1 For example, the inner diameter of the yoke is 62 mm, the wall thickness of the magnet is 611II11, and the wall thickness of the aluminum magnet cover is 0.1 to 0.3 mm. If the
The difference between "outer diameter A" and "inner diameter B", i.e. rA-BJ, is 0.3
Good results have been obtained with approximately 0.7 mn+. Furthermore, it goes without saying that after the magnetic cover is press-fitted, a filler such as an adhesive may be filled between the yoke and the magnetic cover. In addition, in the present invention, as described above, it is possible to completely eliminate the need for the ironing work of the magnetic cover, but it is acceptable to do the ironing work if necessary, and in this case, the ironing force should be weak. Can be done.

入せしめることができ。[Operations and Effects] In summary, since the present invention is constructed as described above, the magnets installed in the yoke are covered on the inner circumferential side by the inner magnet cover, and are not exposed at all. Therefore, when assembling a permanent magnet rotating machine, there is no problem such as sometimes the edges of the magnets chipping off, or the magnets peeling off from the yoke due to shock or temperature changes during use. Since the magnet cover has a larger diameter than the inner circumferential surface of the magnet, the magnet corresponding part can be attached to the inner circumferential surface of the magnet by simply press-fitting it into the yoke that holds the magnet. It can be press-fitted in an uneven state that is deformed along the surface.

There is no fear of deterioration or cracking, and high-quality permanent magnet rotating machines can be produced in large quantities with high efficiency.
