Abstract
A winding electric wire enables a space factor to be increased and an eddy current to be suppressed, despite using an easy winding process. A winding electric wire is configured such that one enameled wire or a plurality of enameled wires bundled in parallel or in a litz form are braided so as to be formed into a belt-like rectangular or square wire shape having flat braided wires forming flatly-molded layers the number that is two or a multiple of two.
Claims9
An electric wire for winding, which is a band-shaped flat wire or square wire and composed of a two-layered or two multiple-layered flat braided wire in which one enameled wire or a plurality of enameled wires bundled in parallel or in a litz shape is braided and molded flat.
A coil for a rotating machine, wherein an electric wire for winding is a band-shaped flat wire or square wire and composed of a two-layered or two multiple-layered flat braided wire in which one enameled wire or a plurality of enameled wires bundled in parallel or in a litz shape is braided and molded flat, and
- the electric wire for winding is wound.
A method of manufacturing an electric wire for winding, comprising the steps of:
- round braiding one enameled wire or a plurality of enameled wires bundled in parallel or in a litz shape into a single-layered or double or more layered cylindrical braided wire;
- flat braiding into two-layered or two multiple-layered flat braided wire by molding the cylindrical braided wire flat;
- and
- shaping the flat braided wire as a flat wire or a square wire.
