Title:

INSULATED ELECTRIC WIRE, PRODUCTION METHOD THEREFOR, COIL AND COIL PRODUCTION METHOD USING SAME

Document Type and Number:

WIPO Patent Application WO/2018/173608

Kind Code:

A1

Abstract:

This insulated electric wire comprises an insulation coat covering a flat rectangular conductor wire whereof the transversal cross-sectional shape is rectangular. The insulation coat comprises an inner layer covering the surface of the flat rectangular conductor wire, and an outer layer covering the surface of the inner layer. In the rectangular transversal cross section of the flat rectangular conductor wire, among two short sides opposing one another and having an identical length, one of the short sides is covered by the inner layer whereof the thickness (t1) is greater than the thickness (t2) of the inner layer covering the other short side (which includes t2 = 0). The elastic modulus of the inner layer is smaller than the elastic modulus of the outer layer, or the yield stress of the inner layer is smaller than the yield stress of the outer layer. Alternatively, the elastic modulus and the yield stress of the inner layer are both smaller than the elastic modulus and the yield stress of the outer layer.
