Abstract
A method for evaluating a vibration behavior of an electric motor includes: determining a vibration value of the electric motor by measuring an acceleration and/or speed of vibrations of the electric motor using a vibration sensor of the electric motor, wherein vibrations are measured in at least one direction, said vibration value representing each of the at least direction measured, determining a current rotational speed (n) of the electric motor, comparing said vibration value with a reference value for the current rotational speed, and determining an evaluation measure for evaluating the vibration behavior of the electric motor based on the comparison of the vibration value with the reference value. Furthermore, a corresponding electric motor and a system consisting of the electric motor and a test system is disclosed with which the vibration behavior of the electric motor can be calibrated and reference values can be generated.
