品を提供できない問題があった。BACKGROUND ART Conventionally, insulation treatment of electrical parts such as a motor rotor and a stator has been performed by dropping an insulating varnish using induction heating. In this case, the heating temperature is controlled at the iron core, which is the body of the rotor or stator. However, since there is an insulator between the body and the coil, the humidity during the dripping process is as follows:
Among the temperatures (I[[) of I#xnd], the isobody part has the highest temperature, and the temperature decreases in the following order. For this reason, if the temperature is controlled in the part of the coil that is subjected to insulation treatment, the insulation between the body made of the iron core and the coil will be destroyed, making it impossible to provide electrical components that meet predetermined specifications.
