Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing an insulated coil exhibiting excellent withstand voltage characteristics and high thermal conductivity in which an inorganic particle layer can be formed between mica flake layers while making the thickness of the insulation layer not increased. SOLUTION: The manufacturing method is characterised in that the surface of a mica layer sheet where a glass cloth is stuck, is coated with a mixture of inorganic particles having a thermal conductivity of 5 W/mK or above, resin and a solvent to form a mixture layer of the inorganic particles, the resin and the solvent. The mixture layer is then cut by means of a doctor blade and pressed to provide a high thermal conduction layer. Subsequently, the mica sheet provided with the high thermal conduction layer is cut to produce a mica insulation tape which is wound around a coil conductor. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PURPOSE:To make good winding of tape and to obtain appropriate flexibility by impregnating the resin consisting of an acid anhydride and an epoxy resin, and hardening after forming a main insulation layer winding the insulating tape which retains a hardening accelerator and drying previously. CONSTITUTION:Each one or more monoalkyl ether of a metal acetyl acetonate, an acid anhydride and monoethylene glycol or polyethylene glycol are reacted as a hardening accelerator and the obtained product is retained in an insulating tape made of a synthetic mica tape. Then, a main insulation layer is formed by winding the tape and after dried previously, the resin of main components of an acid anhydride and an epoxy resin is impregnated in the main insulation layer and the layer is hardened. This method avoids that the hardening accelerator is volatilized and dispersed even by previous drying and improves taping works.

Abstract: PURPOSE:To manufacture a stabilizer coil without the need of varnish impregnation process by a method wherein an insulating resin sheet once softened under heating and thereafter hardened is used instead of craft insulating paper. CONSTITUTION:An electric wire 7 is wound around a bobbin 6 in alignment in the form of multilayers. At this time, a resin sheet 8 is interposed between each pair of adjacent layers. The resin sheet 8 is formed of such a resin, e.g., epoxy resin, that is once softened under heating and thereafter hardened. A core 9 is inserted in the coil 4, which is pressed by pressure plates 10 from above and below as well as the left and right and then heated. The resin sheet 8 is deformed under heating to fill up gaps between wires and thereafter hardened. By so doing, it becomes possible to fill up an insulator for insulating the coil without the need of varnish impregnation process, and hence to facilitate the manufacture. In addition, the coil can be reduced in its size.

Abstract: PURPOSE:To enhance the reliability of an insulated coil by detecting the fact that prepreg resin becomes fluidized state and then applying the prescribed total pressure and high temperature, thereby enabling to readily reduce the voids in the resin even under low planar pressure. CONSTITUTION:A prepreg insulating tape is wound on a conductor 1 to form an insulating layer 2, lead wires 4 are conneted to the two electrodes 3, and are aligned in parallel on the surface of the layer 2 to the two electrodes 3. DC 500V is applied between the lead wires 4 and 4, and the surface resistance of the layer 2 is measured. When the conductor 1 is energized and the prepreg resin of the prepreg insulating tape forming the layer 2 is converted from solid state to liquid state, the resistance between the electrodes 4 and 4 will abruptly decrease. After this state is detected, the prescribed total pressure and high temperature are applied.

Abstract: 【課題】放熱性の向上が図られたコイル部品およびその製造方法を提供する。 【解決手段】 コイル部品10においては、上コイル部15においては、端部E1を構成する端部巻回部15aが引出導体19Aに接続されているため、引出導体19Aが端部巻回部15aから熱を吸収して端子電極20Aを介して外部に放熱することができる。加えて、引出導体19Aは、隣接巻回部15bを覆うように形成されているため、隣接巻回部15bからも熱を吸収して、端子電極20Aを介して外部に放熱することができる。すなわち、上述したコイル部品10は、引出導体19Aが端部巻回部15aだけでなく隣接巻回部15bからも熱を吸収することで、コイル部品10では放熱性の向上が実現されている。 【選択図】図9
