Method for determining the speed and the position of a rotating shaft comprising the detection of a series of values relating to vectorial parameters within a given time interval, the digitalization of said values, the processing of said values by means of a suitable program which envisages the software implementation of a phase lock loop comprising: phase comparison of the digitalized data, the error calculation on the basis of the data within the loop, the adjustment/filtration of the data, the integration of the data, and the reintroduction of the data into the loop, suitably adapted to data scale factors, the angular velocity and angular position values of said shaft being retrieved for each instant.
