Abstract: 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.

Abstract: In a frame structure of a motor, when the number of angles of a frame is 4M (M is a natural number, and M≥1), and the number of slots of an armature core is 6N (N is a natural number, and N≥1), the armature core is inserted into the frame in such a manner as to form a variation θ within a predetermined range in a circumferential direction between a reference line that is orthogonal to two opposing sides of the frame and passes through a rotation axis of the frame, and a straight line linking magnetic poles symmetric about a point with respect to the rotation axis.

Abstract: A stator sub-assembly with a connector includes a stator sub-assembly including a stator core and a rigid wiring board, and a connector fixed to a connector mounting part of the rigid wiring board in such a way that it is opposed to the stator core in the radial direction of the frame. A groove part that extends in the axial direction from an opening in the axial direction and accommodates the connector and the connector mounting part is formed in an inner peripheral surface of the frame. A window part for an opponent connector to mate with the connector accommodated in the groove part is formed in the frame. The window part opens in an outer surface of the frame and an inner surface of the groove part, and has an unbroken inner peripheral surface.
