Field of the Invention The present invention relates to a high-temperature or high-pressure environment or a special atmosphere filled with high humidity, radiation, chemicals, etc., particularly ammonia, that is, a special atmosphere different from a normal atmospheric atmosphere. The present invention relates to an electric device coil such as a motor used in an environment and a method of manufacturing the coil.

得るものとする必要はない。2. Description of the Related Art Conventionally, there is a canned motor as a motor used in a special environment different from a normal atmospheric atmosphere as described above. The canned motor is a motor in which the coil containing the insulator is covered with a metal can to protect the coil containing the insulator from being directly exposed to the special environment. Since the material does not deteriorate, it is not necessary that the insulator used be able to withstand the special environment.

大型になるという問題もある。On the other hand, canned motors have many disadvantages due to the use of cans. For example, since a coil including an insulator is covered with a can, the cooling efficiency of the coil is deteriorated, and the motor becomes large in size. Further, since the can material is interposed between the stator and the rotor, the gap between the stator and the rotor necessarily increases, and the magnetic resistance increases in proportion to the increase in the gap. Therefore, it is necessary to increase the current to compensate for this, and there is also a problem that the motor becomes large.

材料のみで汎用モータを製造することは不可能に近い。[0004] Alternatively, if an electric device coil insulated only with an inorganic insulating material instead of an organic insulating material used for a general-purpose motor can be formed, the size can be reduced. This is because many inorganic insulating materials are chemically stable and have excellent environmental resistance, and can be configured as a can-less motor. However, the inorganic insulating material is remarkably inferior in workability as compared with the organic insulating material, and it is almost impossible to manufacture a general-purpose motor using only the inorganic insulating material with the current technology.

The motor coil body 9 is formed using an insulated wire 7 in which the insulating film 8 is wound around an aluminum wire 1 to form an insulating film layer 2 on both surfaces of which are covered with Teflon materials 8-1 and 8-1. Then, the motor coil body 9 is inserted into the slot 6 of the motor stator core 10, and the entire motor stator core 10 is heated. As a result, the Teflon material 8-1 in contact with the aluminum wire 1 becomes
-2, and the Teflon material 8-1 outside the polyimide tape 8-2 is uniformly melted, and the polyimide tape 8-2 is melted.
And the surface of the polyimide tape 8-2 is not directly exposed to a special environment.

Further, the motor coil body 9 constitutes the insulated wire 7 in which the insulating film 8 is formed by winding the aluminum wire 1 on the polyimide tape 8-2 and covering both surfaces of the polyimide tape 8-2 with Teflon materials 8-1 and 8-1. Since the insulated wire 7 is formed in the motor coil body 9 having a predetermined shape, the stress when bending the insulated wire 7 can be reduced by the displacement of the insulating film 8. Further, since the overlapping portion of the insulating film 8 is the Teflon material 8-1, it is very slippery and easily slips.

Accordingly, there is no deterioration of the insulating film 8 due to creep or the like.

However, the present invention is not limited to this. For example, the motor coil body 9 may be mounted on another heating jig and heated to melt the Teflon material 8-1 of the insulating film 8 to be integrated. Further, in the above example, an aluminum wire was used as the conductor wire, but it is obvious that the conductor wire is not limited to the aluminum wire.

てた状態で容易に製造することができる。According to the second and third aspects of the present invention, the coil of the electric device is inserted into the iron core slot, and the iron core is heated together with the core to melt the Teflon material covering the polyimide film of the insulating film. Since the Teflon material of the insulation film between the wires is also melted and integrated, it is used in a special corrosive environment, especially in the presence of ammonia, without using a special jig for heating the coil of electric equipment. It is possible to easily manufacture a coil of an electric device suitable for the assembly in a state where the coil is assembled with an iron core.
