ABSTRACT:
A manufacturing method for a diamond coil for a rotating electric machine comprises bending a straight conductor in a first plane at eight points so as to produce coil leads, coil ends, and coil straight portions. The conductor is next twisted about its longitudinal axis so as to bend the coil ends out of the first plane. The conductor is then bent in two in a second plane, which is perpendicular to the first plane and which includes the longitudinal axis of the conductor, until the two leads of the conductor point in approximately the same direction.
