摘要： A bobbin structure of an armature of a three-phase motor having 6N (N is a natural number) slots and 3N coils per phase, the bobbin structure including: a main pole into which a winding bobbin around which a coil is wound is inserted; and an auxiliary pole into which an empty bobbin around which the coil is not wound is inserted. The main pole and the auxiliary pole are placed in a circumferential direction with respect to a rotation axis, and a contact portion where the empty bobbin and the winding bobbin are in contact with each other is formed on each of an outer peripheral side and an inner peripheral side of the slot formed between the main pole and the auxiliary pole.

摘要： 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 sheets and the winding are molded with the molding resin, the non-coupling portion delimits an opening window portion in an inner peripheral surface of the iron core, and the opening window portion is filled with the molding resin.

摘要： Provided is an armature structure of a three-phase motor which includes: 6N (N is a natural number) slots; 3N coils per phase; 3N main poles; and 3N auxiliary poles. In the armature structure of a three-phase motor, a coil wound around a winding bobbin inserted into the slot is wound around the main pole, the coil is not wound around the auxiliary pole, the main poles and the auxiliary poles are alternately placed, the winding bobbin includes a barrel portion and a flange portion, the barrel portion is in contact with a side surface in a circumferential direction of the main pole in the slot, the flange portion rises in the slot from the barrel portion along a first outer peripheral bottom portion of the slot, a side surface in the circumferential direction of the auxiliary pole, an outer peripheral surface of the coil, and a second outer peripheral bottom portion of the slot define a gap area that is not occupied by the coil, in the slot, and the second outer peripheral bottom portion is continuous to the first outer peripheral bottom portion, and extends in a direction intersecting the first outer peripheral bottom portion.
