Abstract (en)

[origin: FR2774525A1] The invention concerns an interference suppression system in an engine with permanent magnets activating a functional motor vehicle element, wherein the engine (1) comprises powering brushes (8, 9), connected to an external power source (12) with wires (10, 11) and a metal field magnet frame (2). The invention is characterised in that each brush (8, 9) is connected to the engine metal field magnet frame (2) through at least an interference suppression capacitor (13, 14) and the engine (1) metal field magnet frame (2) is connected to the vehicle earth connection (15).
