Abstract

The invention relates to a method for determining the position of a rotor of an electric machine, comprising the following steps: the possible potential positions of the rotor (23) are determined, a target position (24 ) is determined, a commutation for reaching the target position (25) is applied and the rotational direction of the rotor (26) is determined.
