<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a motor coil, to provide a coil of a motor, and to provide a stator of a motor wherein the space factor of a flat conductor in a slot in a stator core can be enhanced. <P>SOLUTION: The manufacturing method for a coil is such that: one face of a flat conductor 15 having a rectangular cross section is abutted against a guided shaft 83; edgewise bending is carried out to bend the one face in the direction of a short side of the rectangular sections along a curved surface provided in the guided shaft 83; and a motor coil 10 spirally wound is thereby formed. A deforming mechanism 62 is provided which deforms the thickness changing portions 15a equivalent to the four corners of the coil 10 throughout the width of the flat conductor 15 so that the thickness equivalent to the length of a short side of the rectangular cross section of the flat conductor 15 when the flat conductor 15 is subjected to edgewise bending. The coil 10 is formed by deforming the thickness changing portions 15a of the flat conductor 15 by the deforming mechanism 62 and subjecting the thickness changing portions 15a of the flat conductor 15 to edgewise bending. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
