Abstract

A method for manufacturing a distributed straight-angle armature winding according to the present invention comprises a step (a) of preparing a raw material in which at least a pair of intra-slot winding areas and an end winding area provided between the pair of intra-slot winding areas are continued, a step (b) of forming an inclined surface by processing a contact surface in contact with an inner surface of a slot of at least a stator of the circumferences of the pair of intra-slot winding areas, and a step (c) of bending a space between the end winding area and the intra-slot winding area.

Claims (20)

1. A method for manufacturing a distributed straight-angle armature winding comprising:

a step (a) of preparing a raw material in which at least a pair of intra-slot winding areas and an end winding area provided between the pair of intra-slot winding areas are continuous;

a step (b) of forming an inclined surface by processing a contact surface in contact with an inner surface of a slot of at least a stator of the circumferences of the pair of intra-slot winding areas; and

a step (c) of bending a space between the end winding area and the intra-slot winding areas;

wherein in the step (b), the intra-slot winding areas are pressed using a first press tool having a first press groove of which a lower portion is opened,

wherein a plurality of first press tools is provided to have different standards to correspond to the intra-slot winding areas and the end winding area.

2. The method for manufacturing the distributed straight-angle armature winding of claim 1 , wherein in the step (b), a surface outside the contact surface of the circumferences of the pair of intra-slot winding areas is further processed so that a height of the intra-slot winding areas are lower than a height of the end winding area.

3. The method for manufacturing the distributed straight-angle armature winding of claim 1 , wherein in the step (b), the circumference of the intra-slot winding areas are processed using a rolling roller.

4. The method for manufacturing the distributed straight-angle armature winding of claim 1 , wherein in the step (b), the intra-slot winding areas and the end winding area are simultaneously pressed using a second press tool in which the first press tools having different standards are integrally formed.

5. The method for manufacturing the distributed straight-angle armature winding of claim 1 , wherein in the step (c), the raw material is positioned on a circumference of a bending base jig and the end winding area and the space between the end winding area and the intra-slot winding areas are bent by moving a bending roller along the circumference of the bending base jig.

6. The method for manufacturing the distributed straight-angle armature winding of claim 5 , wherein in the step (c), the bending is performed while the raw material is pressed using a bending cover jig of pressing the raw material from the top of the bending base jig.

7. A method for manufacturing a motor comprising:

a step (a) of preparing a raw material in which at least a pair of intra-slot winding areas and an end winding area provided between the pair of intra-slot winding areas are continuous;

a step (b) of forming an inclined surface by processing a contact surface in contact with an inner surface of a slot of at least a stator of circumferences of the pair of intra-slot winding areas;

a step (c) of manufacturing a distributed straight-angle armature winding by bending a space between the end winding area and the intra-slot winding areas;

a step (d) of inserting the intra-slot winding areas of the distributed straight-angle armature winding into each selected slot of the stator in which a plurality of slots is formed in a circumference direction; and

a step (e) of connecting the intra-slot winding areas of different distributed straight-angle armature windings inserted into the plurality of slots to each other,

wherein in the step (b), the intra-slot winding areas is pressed using a first press tool having a first press groove of which a lower portion is opened,

wherein a plurality of first press tools is provided to have different standards to correspond to the intra-slot winding areas and the end winding area.

8. The method for manufacturing the motor of claim 7 , wherein an insulating coating having a high elongation rate is formed on the circumference of the raw material.
