Abstract (en)
[origin: EP1575149A1] A tator-bar 15 having a similar cross-sectional shape to that of the segments 3 is formed by drawing. Segments 3 for a flat commutator are formed by punching out the segments 3 from the tator-bar 15 in a direction Z perpendicular to a drawing direction X. The drawing direction X of the tator-bar 15 is arranged to be substantially the same as the sliding direction of the brush on the segments 3. Simultaneously, surfaces subjected to drawing are arranged to constitute brush sliding surfaces 4 of the segments 3. Anchor parts 14 which serve as a stopper to prevent falling off of the segments 3 are formed on the tator-bar 15 during the drawing. As a result of this, it is possible to manufacture easily, at low costs, segments capable of preventing leakage of resins during a resin mold process of the flat commutator. <IMAGE>
