This paper presents the reduction of iron loss on laminated stator cores by the secondary current heating method, which has been previously proposed. In order to apply the proposed method to laminated motor stator cores, including teeth, an additional two attempts were conducted and the effectiveness of heat treatment by the method was examined.
