Abstract (en)

[origin: FR2895166A1] The method involves comparing, in a control box (19) of an electromagnetic retarder, a theoretical intensity (It) of a current injected in primary coils (8) by the box and an effective intensity (Ie) of the current circulating in the coils for identifying a defect when difference between the intensities is greater than a threshold value. The comparison step includes the determination of the difference between the theoretical intensity and a minimum or maximum value of the effective intensity during a predetermined time interval. An independent claim is also included for an electromagnetic retarder.
