Summary:The invention relates to a method for operating a multi-phase electric machine (2), wherein control voltages (UA, UB, UC) to be applied to phase windings of the electric machine (2) are provided according to a predefined commutation method, wherein, if a sudden change in state as defined by the predefined commutation method is detected from a state in which one of the phase windings is switched off to a state in which the control voltage (UA, UB, UC) is applied to the relevant phase winding, the following steps are carried out: immediate application of a provided intermediate voltage (UZ); and application of a voltage profile produced from a predefined, chronological, constant profile from the intermediate voltage (UZ) to the control voltage (UA, UB, UC) of the relevant phase winding, until the control voltage (UA, UB, UC) to be applied is reached.
