The structure comprises a laminated core having an annular core portion and a facing core portion that extends from the annular core portion toward an opposing machine member. A coil is wound with a toroidal winding about the annular core portion of the laminated core. A partial laminating core is laminated on the facing core portion of the armature to enlarge the facing surface opposite the opposing machine member. The total lamination thickness of the facing core portion and partial laminating core portion is larger than the thickness of the annular core portion.
