    摘要: A method for controlling a synchronous electric machine (2) comprising a stator and a rotor encompasses the following steps: the machine (2) is operated at a deceleration moment (MP) such that a rotor speed of the machine is reduced; the rotor movement of the machine is monitored, and when a rotation in the opposite direction or a rotor speed (v) of nearly zero with a transition into a blocked mode is detected, at least one electric input variable (I; iu, iv, iw) of an electric stator system of the machine is adjusted in such a way that an effective internal moment (MB) of the machine is generated at the beginning of the blocked mode, said internal moment (MB) being smaller than the deceleration moment (MP). The electric input variable (I; iu, iv, iw) is adjusted in this way until a stable equilibrium between an external moment (MA) affecting the machine and the internal moment (MB) has been reached by moving the rotor and under the influence of said external moment (MA).
