Abstract (en)
[origin: EP1610425A1] Each of two brush springs (6) has a long straight shaft (7) and is made of electrically conducting material. A C-section foil (9) of noble metal on the end (8) of the spring makes contact with the rotor (3) of the electrical machine. The spring support (1) has a flat plate (2) with holes (21) to accommodate the folded clamping end (14) of each spring. The end of the long straight spring portion is multiply-folded. A right-angled joggle (13) is succeeded by a straight portion engaging the side of the hole. A gentle curve (17) leads to a clamping portion (16) with a S-bend (18), which passes through the hole and ends on a curve (20) directed toward the center of the flat plate.
