Abstract
A method is described for estimating, by measurements taken by an inductive sensor, the time for which an endothermic motor of a tool has operated at predetermined rotating speeds, and an apparatus implementing the method also described. The method in particular includes cyclically measuring, at a pre-set sampling period, an overall time interval by starting at the beginning of the measuring of the overall time interval when a first variation peak of the electromagnetic field is sensed and terminating the measuring of the overall time interval when a last variation peak of the electromagnetic field is sensed. The first and the last peaks are the start and tail ends of a sequence of peaks having a predetermined number of successive peaks, the number of peaks being positive, whole, at least equal to six and a least common multiple of two and three.
