Embodiment Construction
[0017] figure 1 The current collector 1 shown is used for the transmission and commutation of electric current in an electric machine, such as an electric motor or a generator, and is preferably used for a starter of an internal combustion engine. Such starters are designed for extensive starting operations, especially in the case of motor vehicles equipped with a start-stop system for automatically switching off and switching on the internal combustion engine.
[0018] The commutator 1 comprises a cylindrical current collector 2 which is non-rotatably connected to the armature of the electric machine, the armature being rotatably mounted in the stator. Furthermore, the commutator 1 comprises a plurality of carbon brushes 3 which, in the exemplary embodiment shown, are in contact with diametrically opposite radially outer peripheral surfaces or a The rolling surface of the disk transmits the current introduced into the corresponding carbon brush 3 via the twisted wire 4 to th...
