摘要： A coil conductor for a dynamoelectric machine which is a coil conductor to be inserted into slots of an iron core of a dynamoelectric machine, the coil conductor being made of a plurality of wire elements compression-bonded to each other by press-forming so as to have a substantially rectangular cross-section. The wire elements may be twisted by at least 360 degrees and the twisted wire elements may be further twisted. The coil conductor includes straight sections and crossover sections, providing an overall shape of a crank wound in a serpentine manner and the straight sections have different intervals that are different in accordance with the different periodical numbers n th and (n+1) th. The coil conductor for a dynamoelectric machine may further include an electrical insulating material disposed around the conductor of a square cross-sectional shape that is formed by simultaneously pressing the conductor bundle with an electrical insulating material placed therearound before press-forming.
