Abstract
An armature molded structure includes a cylindrical iron core used for a molded structure of a motor armature; a winding; and molding resin, wherein the iron core includes first core sheets and second core sheets, the first core sheet includes first magnetic poles placed along a circumferential direction of the iron core, tip portions, on an inner peripheral side of the iron core, of adjacent first magnetic poles form a coupling portion coupling the adjacent first magnetic poles, the second core sheet includes second magnetic poles placed along the circumferential direction of the iron core, tip portions, on the inner peripheral side of the iron core, of adjacent second magnetic poles form a non-coupling portion separating the adjacent second magnetic poles, the first and second core sheets are laminated along a central axis direction of the iron core in such a manner that the coupling portions coincide with each other, the non-coupling portions coincide with each other, the coupling portion and the non-coupling portion coincide with each other, the winding is wound around the first and second magnetic poles of the laminated first and second core sheets, the first and second core s…
