の電磁振動などの応力により割れる問題も発生した。However, ceramic plates commonly used for high-temperature applications have low toughness and high sensitivity to notches, making them difficult to cut and difficult to process into complex shapes. Also, if you drive a wedge into a part with an uneven surface, such as the slot teeth of a laminated iron core in a rotating machine, it will often break.
The wedge was inserted with great care. Furthermore, there was also the problem of cracking due to stress caused by electromagnetic vibration during operation.

る。(Function) Ceramic putty has appropriate fluidity and can be easily filled into slot openings by being pushed. When pressed, the ceramic putty penetrates into minute irregularities on the surface of the core and into narrow gaps created between the ground insulation sheet and the core. When the ceramic putty hardens, it acts as a wedge with strong ceramic properties, and the electrical winding, iron core, and insulating sheet become integrated through the ceramic putty.

内周面は鉄心内周面に合せて仕上げる。FIG. 1 shows details of the slot portion of the stator core of a high-temperature vacuum motor, and the core 1 is provided with a slot 2. As shown in FIG. First, a 0.13 mm thick quartz glass fabric with a thickness of 30 μm was laminated on both sides using ceramicized silicone (product name AY49-208 from Toshi Silicone Co., Ltd.) as an adhesive.
A peelable mica sheet reinforced with double-sided glass woven fabric is laid in a U-shape in the slot 2 of the iron core 1 as a ground insulation sheet 3 for ground insulation. The insulated wire 4, which has been previously wound in this insulating sheet, is dropped through the slot opening 7. At this time, an interlayer insulating sheet 6 is placed between the layers of the winding wire. Next, the insulated wire is surrounded by folding the ground insulating sheet at the slot opening. After that, the folded part 1 of the ground insulation sheet
The slot opening 7 is filled by pressing a ceramic putty 9 (Hyper Random °C manufactured by Showa Denko) while holding down the ceramic putty 9 . After filling is completed, remove the putty that protrudes from the end of the core, and then finish the molding. Also, the inner peripheral surface of the iron core is finished to match the inner peripheral surface of the iron core.

仕上がり、ごみなどが付着しにくくなる。Further, on the surface of the ceramic putty 9, a paste-like inorganic coating material 12 having better fluidity than the ceramic putty is applied.
(For example, Showa Denko Hyperrandom C901, C-

ックが入らないように留意する。Let the whole thing air dry for a few hours. At this stage, the ceramic putty becomes a hardened product with excellent heat resistance and corrosion resistance. Thereafter, the temperature is raised stepwise and finally dried at about 350° C. for about 15 hours to volatilize the solvent and inorganize the coating film of the electric wire and the adhesive in the double-sided glass woven reinforced peelable mica sheet. After drying is completed, it is slowly cooled and care is taken not to apply heat to the ceramic and cause cracks to form.
次に本実施例の作用について説明する。Next, the operation of this embodiment will be explained.

、大きなひずみをセラミックパテに誘起するので、クラ
ック発生の原因になるからである。After hardening, the ceramic putty 9 filled in the slot opening acts as a solid wedge to prevent the electrical winding 5 from jumping out of the slot due to vibration, etc., and also prevents insulation damage of the insulated wire due to friction caused by vibration. To prevent accidents, we folded the ground insulating sheets to surround the electrical windings to prevent direct contact between the ceramic putty and the insulated wires.If they came into direct contact, thermal stress caused by starting and stopping the motor would occur. This is because electromagnetic force is transmitted directly from the insulated wire to the ceramic putty, inducing large strains in the ceramic putty, which can cause cracks to occur.

寿命、信頼性向上が実現できる。According to this embodiment, a wedge made of a ceramic plate is not hammered in and inserted into the slot opening, but the slot opening is filled with ceramic putty and then hardened, so that the ceramic putty acts as a wedge. The wedge does not break during assembly, improving reliability, safety, and workability. Furthermore, since the iron core and the winding are integrally hardened, the winding can be firmly supported and fixed, and the life of the electric winding can be extended and the reliability improved.
次に本発明の他の実施例について簡単に述べる。Next, other embodiments of the present invention will be briefly described.

ある。This method uses alumina, silicon carbide, alumina-boria-silica (
Everything is the same except that a ceramic putty containing inorganic short fibers such as silica (trade name Nextel, manufactured by 3M Company) was used.
このようにすると作業性は前記実施例に比べてやや劣る
が、無機質の短繊維の補強効果が出るため、より強固な
巻線の支持固定ができる。Although the workability is slightly inferior to that of the above-mentioned embodiment, the reinforcing effect of the inorganic short fibers is produced, so that the winding wire can be more firmly supported and fixed.
さらに前述の実施例では、絶縁電線をスロットに挿入後
セラミックパテを充填・硬化する方法について述べたが
、予めスロット開口部のみにセラミックパテを充填・硬
化した後、電線をスロット内に収納することもできる。Furthermore, in the above embodiment, a method was described in which the insulated wire was inserted into the slot and then filled with ceramic putty and hardened. However, it is also possible to fill and harden the ceramic putty only in the slot opening before storing the wire in the slot. You can also do it.
この場合擬似巻線をスロット内に置き、スロット開口部
にセラミックパテを充填・硬化した後、擬似巻線を抜き

、信頼性向上が実現できる。In the present invention, the slot opening is filled with ceramic putty and hardened, and the ceramic putty acts as a wedge.
Since the electric winding, the iron core, and the wedge can be integrated, the electric winding can be firmly supported and fixed, and the life of the electric winding can be extended and reliability can be improved.
