If it is necessary to reduce the thickness of the wire as much as possible, the tension of the wire in the winding (to prevent quenching) will apply an indentation force to the winding frame cylinder fil, causing distortion. = The amount of surface strain per hit decreases as the number of layers increases, but in magnets with a large number of windings and layers, the accumulated strain becomes quite large, which may lead to plastic deformation of the winding frame, and even This may cause quenching.Therefore, in such a case, it is necessary to manage the winding tension according to the thickness of the width frame cylinder.
