Abstract
A method is disclosed for determining a vibration behavior of an electric motor, in particular an electric motor of a fan, and/or its installation environment, wherein a rotary motion of a rotor of the electric motor can be braked in a braking process. The disclosed method comprises generating a jolt by triggering a braking process or an acceleration process or by changing a braking process or an acceleration process, generating detected vibration values by detecting vibrations of at least a part of the electric motor by means of at least one vibration sensor, determining spectral components by means of a frequency analysis of the detected vibration values, and determining a vibration behavior of the electric motor and/or its installation environment by evaluating the spectral components. Further disclosed is a corresponding electric motor, fan, and system, each of which may be configured to carry out the method.
