PURPOSE:To increase the efficiency of a motor by so bonding a plurality of iron plates as one set that the surfaces alternately having steps eliminate the steps of the opposite surfaces to increase the bonding area of the bonded portion to decrease a magnetoresistance. CONSTITUTION:A core is split into cores 1, 8, which have a plurality of ion plates as a set alternately including steps on the surfaces to be bonded of bonded portions 6, 7, 13, 14 containing projections 4, 5, 11, 12 at the outer peripheral side on the ends 2, 3, 9, 10. The plurality of iron plates are so bonded as a set that the surfaces alternately having steps eliminate the steps of the opposite surfaces to form a stator of a capacitor motor.
