Zusammenfassung:	A method for switching on a multi-phase electrical machine in a motor vehicle, the multi-phase electrical machine having a rotor having a rotor winding, and a stator having a multi-phase stator winding; a phase voltage having a phase voltage vector being applied, in a PWM operating mode, to the stator winding, said vector corresponding in terms of absolute magnitude and direction to a pole wheel voltage vector of a pole wheel voltage; the rotor winding being energized by an excitation current; and the PWM operating mode being deactivated, and a block operating mode for application of the phase voltage being activated, when at least one parameter influencing the pole wheel voltage reaches a threshold value.
