Abstract

PURPOSE: A hollow part is formed in the coil winding frame materials provided in a magnetic path, and this inside is lined by porous materials containing liquid or only liquid is enclosed in this part. Then, the coil is cooled efficiently by utilizing the evaporation phenomenon of liquid, thereby increasing a working current value.
