Abstract
The invention relates to an alternator including at least one concentration peak (80) for the accumulation of electric charges (90) which is formed on the external face (19) of a ease bearing stator and extending in relief in a direction of the part (84) of a flexible belt driving element (80) in such a way that electrostatic charges are removed by electric arcs formed between the peak (80) and the part (84).
Claims8
A motor vehicle alternator comprising:
- a casing carrying a stator, the electrical potential of which is connected to a vehicle earth;
- a rotor whose central shaft is mounted for rotation in the stator, a rear axial end of the rotor shaft which extends axially outside the stator, carrying a pulley for rotationally driving the shaft driven in rotation by a flexible driving element;
- and,
- a contactless electrical connection on a controlled external path between the casing and the flexible driving element for eliminating electrostatic charges on the alternator, said contactless electrical connection including at least one concentration peak for the electrical charges which is formed on an external face of the casing, and which extends in relief in the direction of a facing portion of the pulley.
