Title:
WINDING ELECTRIC WIRE, ROTARY MACHINE COIL USING SAME, AND METHOD FOR MANUFACTURING WINDING ELECTRIC WIRE
Document Type and Number:
WIPO Patent Application WO/2018/101378
Kind Code:
A1
Abstract:
A winding electric wire according to one embodiment of the present invention enables a space factor to be increased and an eddy current to be suppressed, despite using an easy winding process. A winding electric wire 1 is configured such that one enameled strand (1a) or a plurality of enameled strands (1a) bundled in parallel or in a litz form are braided so as to be formed into a belt-like rectangular or square wire shape comprising flat braided wires forming flatly-molded layers the number of which is two or a multiple of two. By spirally winding the electric wire, a coil that is easily wound regardless of the presence of a core, that has a high space factor, and that causes less eddy currents is obtained.
