A method and system for detecting the variations of speed (R) of a rotor. Signals are measured representative of the march-past of the teeth of a measurement device secured to the rotor for a determined duration (T). The measurements are sampled, digitized and stored to obtain an initial digital vector (B). A detection signal is extracted around a known disturbing frequency (F). The detection signal is compared with a predetermined threshold (SO) and an alert message is delivered in the event of overshoot.
