    • Magnetic flux in a magnetic flux distribution inside a wound iron core for a stationary apparatus is mal-distributed toward the inner periphery side where the magnetic path of a laminated magnetic steel sheet is short with respect to the total lamination thickness and magnetic resistance is small and the inner periphery side on which magnetic flux is concentrated has a high magnetic flux density and increased iron loss, and therefore magnetic steel sheets of different magnetic characteristics are disposed at an arbitrary lamination ratio to make uniform the magnetic flux distribution inside the same wound iron core. In order to make uniform the magnetic flux distribution inside the wound iron core for a stationary apparatus, such a structure is adopted that a magnetic steel sheet having a magnetic characteristic inferior to that on the outer periphery side is disposed on the inner periphery side having a shorter magnetic path and smaller magnetic resistance and a magnetic steel sheet having a magnetic characteristic superior to that on the inner periphery side is disposed on the outer periphery side having a longer magnetic path and greater magnetic resistance to thereby make uniform the magnetic flux distribution in a sectional area of the iron core.
