Title:
STATOR AND JOINING METHOD OF COIL WIRE OF STATOR TO EXTERNAL CONDUCTOR
Document Type and Number:
Japanese Patent JP2022070564
Kind Code:
A
Abstract:
To provide a technique capable of suppressing the displacement of a conductor during welding between a coil wire of a stator and a conductor.SOLUTION: A technique disclosed herein is embodied in a stator with a coil wire. The coil wire includes an insulating portion, a conductive portion, an extending portion, a welded portion, and a connecting portion. In the insulating portion, an insulating coating is applied to the outer surface of the coil wire. In the conductive portion, the insulating coating is removed from the outer surface. The extending portion is exposed from the stator in the axial direction of the stator and extends outward in the radial direction of the stator. The welded portion extends in a direction orthogonal to the extending portion, and the conductive portion to be welded to an external conductor is arranged. The connecting portion connects the extending portion and the welded portion, and is displaced in the direction orthogonal to the outer side in the radial direction. In the stator disclosed herein, the boundary between the insulating portion and the conductive portion is located at the connecting portion.SELECTED DRAWING: Figure 3
