Abstract

PURPOSE:To form a cylindrical vessel type yoke easily, and to decrease the leakage flux of a yoke section by shaping one part or the whole of the yoke through drawing working to the laminate of a magnetic iron plate. CONSTITUTION:A core consists of a cylindrical core leg section 1 and the cylindrical vessel type yoke 2 concentrically surrounding the leg section. Both cylindrical primary and secondary winding 3, 4 is wound on the core leg section 1 so as to concentrically sorround the leg section at the inside of the yoke 2. The yoke 2 is divided into two sections in the axial direction. Each yoke section 2a, 2b is formed through deep-drawing working to the laminate of the magnetic iron plate at that time. Accordingly, the sections of the yoke 2 are utilized effectively, and the leakage flux of the yoke 2 decreases.
