This invention electric current collector ring (7) brush block in order to transmit regards (6) one multiple wire slip element (VDSE) with (3) at least. The brush block with this invention (6), slip direction (9) with approximately phase doing, is distributed is arranged inside the circular arc, the many multiple wire slip element which is connected electrically in parallel has possessed (3). Brush block (6) because of this, the inner wall which curves (12) the VDSE backing which it has had (4), the inner wall (12), VDSE (3) forming, the scaly layer which overlaps mutually (A and B), it is arranged.
