A method of controlling an electric synchronous machine (2) having a stator and a moving part comprises the following steps: operating the machine (2) with a deceleration moment (MP) so that a moving part speed of the machine is reduced, monitoring the moving part movement of the machine, and upon detection of a direction reversal or a speed (v) of the moving part of approximately zero, a transition to a holding mode is effected, adjusting at least one electric supply variable (I; iu, iv, iw) of an electric stator system of the machine such that, at the beginning of the holding mode, an effective internal moment (MB) of the machine is formed that is reduced with respect to the deceleration moment (MP). The electric supply variable (I; iu, iv, iw) is adjusted in this manner until, with movement of the moving part and influence of an external moment (MA) acting on the machine, a stable equilibrium of moments between external moment (MA) and internal moment (MB) of the machine is established.
