Title:
ELECTRIC INSULATED WIRE AND COIL
Document Type and Number:
WIPO Patent Application WO/2010/086944
Kind Code:
A1
Abstract:
Provided is an electric insulated wire having an excellent high-frequency property and an excellent insulating property. The electric insulated wire is comprised of an assembled wire (11) having a circular section formed by assembling seven enamel wires (4) having an noncircular section; and a first insulating coating (1) formed by winding an insulating tape around the outer periphery of the assembled wire (11) to bind the assembled wire (11). The electric insulated wire can reduce the high frequency loss in comparison with a single wire having the same sectional area, and can decrease the outer diameter thereof in comparison with a litz wire having the same sectional area. Further, the binding force for the assembled wire can be easily maintained by winding the insulating tape around the assembled wire, without twisting the assembled wire. Accordingly, the variation of the outer shape of the assembled wire can be reduced, and the insulation property can be improved.
