Abstract
A method for determining the rotor position and the rotational speed of a rotating field machine, including, based on Hall sensor signals, a step of determination of a sector in which a rotor of the rotating field machine is situated and a step of determination of a preliminary rotational speed of the rotating field machine. In a step of determination, the rotor position and the rotational speed are determined based on the sector and on the preliminary rotational speed, an observer of the rotating field machine being used at least for the determination of the rotational speed.
