Abstract
Embodiments of the invention are shown in the figures, where a system for vibration detection is shown, the system comprising: one or more drivelines including a rotatable component rotatable about a rotational axis relative to another component; an electrical machine having a rotor and a stator rotatable with respect to one another, the rotor being arranged to at least one of drive and be driven by a part of the driveline, the electrical machine being adapted to provide signals indicative for at least one of a motion and a force between the rotor and the stator and a torque applied on the rotor; and an analysis unit adapted to receive the signals and to detect a vibration signature of the rotatable component with respect to the other component based on the signals.

A system comprising:
- at least one driveline including a rotatable component rotatable about a rotational axis relative to another component;
- at least one electrical machine having a rotor and a stator rotatable with respect to one another, the rotor being arranged to at least one of drive and be driven by a part of the driveline, the electrical machine being adapted to provide signals indicative for at least one of a motion and a force between the rotor and the stator and a torque applied on the rotor;
- and
- an analysis unit adapted to receive the signals and to detect a vibration signature of the rotatable component of the driveline with respect to the other component based on the signals.
A control system, comprising an analysis unit adapted to receive signals from an electrical machine having a rotor and a stator rotatable with respect to one another, the rotor being arranged to at least one of drive and be driven by a part of a driveline, the signals being indicative for at least one of a motion and a force between the rotor and the stator and a torque applied on the rotor, wherein the analysis unit is adapted to detect a vibration signature of the rotatable component with respect to the other component based on the signals.
A method for detection of vibration at a driveline including a rotatable component rotatable about a rotational axis relative to another component, wherein a rotor of an electrical machine is arranged to at least one of drive and be driven by a part of the driveline, the method comprising the steps of:
- providing, by means of the electrical machine, signals indicative for at least one of a motion and a force between the rotor and the stator and a torque applied on the rotor;
- and
- detecting, by an analysis unit receiving the provided signals, a vibration signature of the rotatable component with respect to the other component based on the signals.
