Edgewise Coil

An edgewise coil which includes a non-circular cross-sectional shaped conductor having a cross-sectional shape defined by a pair of first and second long sides and a pair of first and second short sides, the shaped conductor wire being laminated while being bended with using the first short side as a bending fulcrum so as to form a plurality of laminated wire layers having a rectangular shape in a plan view, wherein

• the pair of long sides include, in a longitudinal cross section in a pre-bending-process state before the shaped conductor wire is bended, a pair of tapered regions extending between both ends of the second short side and both ends of the first short side, and
• the pair of tapered regions, in a longitudinal cross section in the pre-bending-process state, come closer to each other as they approach the first short side.

An edgewise coil which includes a non-circular cross-sectional shaped conductor having a cross-sectional shape defined by a pair of first and second long sides and a pair of first and second short sides, the shaped conductor wire being laminated while being bended with using the first short side as a bending fulcrum so as to form a plurality of laminated wire layers having a rectangular shape in a plan view, wherein

• the pair of long sides include, in a longitudinal cross section in a pre-bending-process state before the shaped conductor wire is bended, a pair of first straight-line regions extending from both ends of the second sides so as to be parallel to each other and a pair of second straight-line regions extending between the pair of first straight-line regions and the first short side, and
• the pair of second straight-line regions are closer to each other than the pair of first straight-line regions.

An edgewise coil which includes a non-circular cross-sectional shaped conductor having a cross-sectional shape defined by first and second width-direction surfaces extending substantially parallel to each other in a state of being spaced apart from each other by T in a thickness direction and in a state of being along both a width direction and a longitudinal direction and first and second thickness-direction surfaces extending substantially parallel to each other in a state of being spaced apart from each other by W which is longer than T in the width direction and in a state of being along both the thickness direction and the longitudinal direction, the shaped conductor wire being laminated while being bended with using a predetermined position of the first thickness-direction surface in the longitudinal direction as a bending fulcrum so as to form a plurality of laminated wire layers having a rectangular shape in a plan view, wherein

• the shaped conductor wire has, in a pre-bending-process state before the shaped conductor wire is bended, a pair of recesses disposed at a position corresponding to the bending fulcrum in the longitudinal direction, the pair of recesses respectively extending from the first and second width-direction surfaces to the first thickness-direction surface.
