Abstract:
A method of making a wave winding for a stator of a three-phase generator, wherein said wave winding (12) is divided into two winding halves (12a, 12b), each of said two winding halves consists of at least one continuous winding wire (15) wound in a circular or polygonal shape or deformed into a star shape, said two winding halves are offset from each other by one pole pitch (p) and arranged in grooves provided in a stator lamination packet (32) so that alternating winding heads (12c) of the two winding halves are formed on both sides of said stator lamination packet around a circumference of said stator lamination packet, said method comprising the steps of:a) winding said at least one continuous winding wire in a first winding direction to form a first winding half (12a) in said circular or polygonal shape;b) switching over said at least one continuous winding wire into an opposite winding direction in a winding loop (21);c) after the switching over of said at least one continuous winding wire, winding said at least one continuous winding wire in the opposite winding direction to form a second winding half (12b) in said circular or polygonal shape;d) simultaneously deforming both said first winding half (12a) and said second winding half (12b) into said star shape;e) after said deforming of step d), rotating said first winding half (12a) and said second winding half (12b) with respect to each other by said one pole pitch (p), whereby said winding loop (21) between said first winding half (12a) and said second winding half (12b) transitions into said star shape.
