1. A rotating field machine having a rotor, and configured with a motor control for controlling at least the rotation and the rotational speed n of the rotor of the rotating field machine, wherein the motor control integrally comprises an oscillation sensor system configured to continuously monitor the oscillation behavior of the rotating field machine by acquiring actual measurement values of occurring oscillations of the rotating field machine depending on the rotational speed n during running operation and to directly adapt control parameters of the motor in relation thereto;
wherein the motor control is configured for storing, depending on the actual measurement values of the oscillation sensor system at one or multiple determined rotational speeds ni, said rotational speeds as rotational speeds nunz which are unacceptable for the motor control, in a system memory of the motor control, such that the motor control does not actuate these rotational speeds nunz during operation.
