Device and Method for Manufacturing Wire for Wound Stator of Automotive Generator and Method

A method for manufacturing a wire for a wound stator of an automotive generator, the method comprising:

• removing a coating of a first section of the wire at a first position;
• moving and holding the wire from the first position to a second position;
• deforming a middle section of the wire into a waved shape such that the wire is formed of a plurality of straight portions and a plurality of U-shaped portions that alternate with each other;
• removing the coating of a second section of the wire at the first position, the middle section connecting the first section and the second section;
• cutting off the first section, the middle section and the second section of the wire from the other part of the wire;
• and
• deforming the first section and the second section into a waved shape.

A method for manufacturing a wire for a wound stator of an automotive generator, the method comprising:

• providing a wire including a core and a coating surrounding the core, the wire being defined to have a first wire unit and a second wire unit, the first wire unit having a first section, a second section and a middle section between the first section and the second section;
• removing the coating of the first section to expose the core thereof;
• holding the first section;
• pressing a plurality of parts of the middle section that are spaced apart from each other to deform the middle section to form a plurality of straight portions and a plurality of U-shaped portions that alternate with each other into a waved shape;
• removing the coating on an end of the second section;
• cutting off the wire to separate the first wire unit from the second wire unit;
• pressing the first section and the second section to deform the first section and the second section into a waved shape, respectively;
• and
• pressing the plurality of straight portions to flatten the cross-sections thereof
