摘要： A step of inserting an insulating paper into a slot of a stator core (second step) is performed, a step of placing a jig at a position that is on a side opposite to a side from which a segment coil is inserted into the slot of the stator core and that overlaps with a protrusion when viewed in an inserting direction of the segment coil (third step) is performed, and then a step of inserting the segment coil into the slot (fourth step) is performed. Therefore, even when the insulating paper is dragged by the segment coil in the process of inserting the segment coil into the slot, the insulating paper abuts the jig and the movement of the insulating paper is restricted, thereby suppressing displacement of the insulating paper from the slot.

摘要： An insulator includes an extended portion extended along the axial direction of a motor stator from an annular member. The extended portion includes at least one protruding portion protruding in the outer-diameter direction from a guide surface that guides a winding in the circumferential direction of a motor stator. This protruding portion includes an abutting surface capable of abutting the winding guided by the guide surface. The abutting surface includes a slant portion that comes close to the annular member toward the outer-diameter direction. The slant portion is capable of abutting a semicircular portion of the winding with the circular cross-sectional shape at the outer-diameter side.

摘要： Disclosed herein are a stator and a method for manufacturing the same. The stator according to embodiments of the present disclosure includes an insulating part and a plurality of stator coils each having two ends electrically connected to form one joint portion. The insulating part is configured to cover at least respective parts of the joint portions, and to provide a distance between neighboring joint portions. Accordingly, a partial discharge caused by a surge between the joint portions of the stator coils may be prevented, allowing operational reliability of the stator to be increased.

摘要： An embodiment relates to a stator and a motor comprising same, the stator comprising: a stator core comprising a yoke and multiple teeth protruding from the inner surface of the yoke; an insulator surrounding a part of the stator core; a coil wound around the insulator; and a molding portion disposed to cover the stator core, the insulator, and the coil. The insulator comprises a first insulator and a second insulator. The first insulator comprises: a body portion around which the coil is wound; and inner guide extending from the inside of the body portion in the perpendicular direction; a first outer guide extending from the outside of the body portion in the perpendicular direction; a second outer guide disposed to be spaced apart from the first outer guide in the outward direction; and a protrusion protruding from the second outer guide in the inward direction. The protrusion has an end portion disposed such that a predetermined gap (G) is formed between same and the first outer guide. The coil has a part disposed between the first outer guide and the second outer guide through the gap (G). Accordingly, it is possible to prevent inhibit the coil from contacting the housing due to injection molding pressure during over-molding of the stator.
