Title:
METHOD FOR MANUFACTURING COIL AND JIG FOR BENDING COIL
Document Type and Number:
WIPO Patent Application WO/2023/032415
Kind Code:
A1
Abstract:
This method for manufacturing a coil comprises: a planar coil forming step for winding a conductor in a plurality of layers (or a plurality of rows and a plurality of layers) to form an air core planar coil; a first heating step for heating the planar coil formed in the planar coil forming step to a predetermined temperature; a bending step for bending at least a portion of the planar coil heated in the first heating step to a predetermined angle in a direction perpendicular to the plane of the planar coil; and a second heating step for heating the bent coil formed in the bending step at a predetermined temperature for a predetermined period of time.
