ABSTRACT:
A structure of an armature of a radial rib winding type rotating electric machine which constitutes at least a member of a stator or a rotor is disclosed. The structure comprises a laminated core having an annular core portion, a radial rib-like core portion that extends radially from the annular core portion toward an opposing member and a facing core portion that is formed at the edge of the radial rib-like core portion to face the opposing member. A coil is wound about the radial rib-like core portion of the laminated core. A partial laminating core is laminated on at least the facing core portion of the armature to enlarge the facing surface thereof opposite the opposing member. The total lamination thickness of the facing core portion and partial laminating core portion is larger than the thickness of the radial rib-like core portion.
