Abstract (en)
[origin: EP0715395A1] The motor has sections (4-6) of the conductive ring around the commutator hub (7) sepd. by radial insulating bars (8,9) and contacted by tangential outer edges (1.1,2.1) of the brush sections (1,2) which are bonded together with an intermediate layer (3) of harder insulating material. During running-in the spacing (3.2) between the end of the insulating layer and the contact surface is established by curvature of the brush surface to a smaller radius. The edges of the brushes are worn away until their entire surface comes into contact with the ring.
