) to form. Here, as the heat-resistant fibers, glass fibers, synthetic fibers such as polyimide, asbestos, etc. are used. Moreover, gold, silver, copper, etc. are used as the metal of the metal plating layer (3). The insulating layer (4) is formed of a synthetic resin such as phenol resin, polyester, or polyethylene, or a face-treated material of synthetic resin such as phenol resin, polyester, or polyethylene, or a silicone resin.

This is to form a child winding (6). The pond portion is constructed in the same manner as a conventional inductance device and constitutes a predetermined electric circuit.

In this embodiment, since the core (2) of the conducting wire is made of heat-resistant fiber, the conducting wire is lightweight, which reduces the negative effect on the start-up characteristics as a remoter, and eliminates the need for a wire drawing process. The electrical conductivity will be achieved by metal plating.

According to this embodiment described above, since the core (2) of the conducting wire is made of heat-resistant fiber, the conducting wire can be made lightweight, and there is no adverse effect on the characteristics of the motor as a rotating device.
