できる。Next, a preferred embodiment of electric motor manufacturing according to the present invention will be described. The following explanation is for manufacturing the stator side by attaching magnets to the inner peripheral wall of the stator yoke, but it also applies to manufacturing the rotor side by attaching magnets to the outer circumference of the rotor yoke. It is possible. The stator yoke 1, which is cast into a cylindrical shape or formed from a rolled plate and welded into a cylindrical shape, has been subjected to the necessary machining, and is mounted on a stage of a wire-cut electrical discharge machining line. Accurately align the axial center of stator yoke 1 and the axial position of the wire electrode between the pair of guides in parallel, and fit the permanent magnet 3 in the predetermined position of the vertical stator yoke 1 according to the setting input program in advance. The concave or convex portions are processed and formed by wire-cut electrical discharge machining. This wire-cut electric discharge machining can be used in conjunction with second cut, third cut, or higher finishing machining as necessary to achieve a surface roughness of preferably about several μ01R11ax, and to improve the machining dimensional accuracy of about ±5 μl or more. It will be completed within that time. The stator yoke that has undergone the prescribed machining can be left as is, or removed from the stage together with the jig and then pre-processed using wire-cut electric discharge machining to form a part similar to or slightly similar to the concave or convex part of the stator yoke 1. Magnet 3 processed and formed into a desired shape with moderate dimensional accuracy
, preferably has heat resistance. Alternatively, it can be attached using a resin adhesive mixed with magnet powder. In addition, in the above-mentioned present invention, the permanent magnet 3 is made of 3m-co alloy, Nd
It is effective in terms of cost/performance when applied to high-performance magnets based on so-called rare earth metal alloys such as -Fe -8 alloys, for example, for high precision permanent magnets based on rare earth metal alloys that are highly hard and fragile. The application of wire-cut electric discharge machining, which requires a small cutting pressure, is appropriate for processing and forming, and since the fitting part between the stator yoke and the magnet has a similar shape, the machining of the same numerical value is required for machining that part. The four parts or convex parts of the stator yoke and magnet can be relatively easily programmed and machined by simply setting the predetermined wire electrode shift draw for the numerical control information of the same numerical dimensions. Since the fitting gap between the magnet and the magnet is small and can be kept uniform as a whole in a predetermined state, the magnetic resistance of the gap can also be made small.

This is something that can be obtained.

機で１／ ２．３の体積とすることができた。Since the present invention has a stator yoke or a rotor yoke with separately molded permanent magnets bonded in a concave and convex manner, heat dissipation is prevented due to dimensional errors caused by misalignment and the adhesive layer when bonded with adhesive. It was possible to eliminate the disadvantages of deterioration of isotemperature characteristics and unevenness of N-wire resistance. And rare earth magnet grains can be used for permanent magnets.
When the magnetic particles and synthetic resin are mixed, molded, and solidified, it is now possible to control the magnetic flux distribution by adjusting the t and It density between the surface and the inside. When an ultra-high polymer material is used as the resin used here, it can have a bearing action and is highly effective. In this case as well, it is preferable to use the same or similar type of resin 17 (FIG. 4) surrounding the magnetic coupling +1 and the outside, and it is also advantageous to mix fiber resin. Furthermore, the gap between the permanent magnet 5 and the armature is controlled (changed) according to the characteristics of the permanent magnet to achieve a uniform magnetic flux density.According to experiments, the gap between the permanent magnet 5 and the armature is 1/2. It was possible to make the volume 3.

FIG. 8 shows a method in which a large number of permanent magnets 3 are fitted into pads 19 made of a flexible, highly transparent material, and the pads 19 are removably fixed to the stator yoke 1 or the rotor yoke 11, depending on the purpose.
