Manufacturing method for winding assembly of rotating electrical machine and manufacturing apparatus for the winding assembly

A manufacturing apparatus for a winding assembly of a rotating electrical machine used in a winding step of winding respective winding members so that each of the plural winding members has plural first straight parts, plural second straight parts, first turn parts connecting the first straight parts and the second straight parts at their one sides, and second turn parts connecting the first straight parts and the second straight parts at the other sides,

• wherein the manufacturing apparatus comprises a rotation block, a fixed block and a wire rod feed mechanism, the rotation block includes a rotation surface rotatable around a rotation axis, the fixed block includes a first and a second surfaces opposite to each other and a shaping surface formed between end parts of the first surface and the second surface, the shaping surface is made to have a substantial semicircular shape with the rotation axis as a center and is extended in a direction of the rotation axis, and the wire rod feed mechanism is constructed to supply plural wire rods in a state where they are arranged substantially in parallel to each other,
• the winding step includes a first and a second wire rod feed steps, and a first and a second wire rod turn steps, at the first and the second wire rod feed steps, the wire rod feed mechanism supplies the plural wire rods such that in a state where they are arranged substantially in parallel to each other, the wire rods extend from the first surface of the fixed block onto the rotation surface of the rotation block and project by a predetermined dimension from the rotation axis, and consequently, lengths of the first and the second straight parts of each of the plural wire rods are set, and at the first and the second wire rod turn steps, the plural wire rods on the rotation surface of the rotation block, together with the rotation block, are rotated, so that the plural wire rods are simultaneously bent along the shaping surface, and the first and the second turn parts are respectively formed.
