1. A method for testing rotors, comprising:

  • coupling a rotor to be tested in a torque-transmitting manner to an electric activating motor;

    setting the rotor in rotation by the activating motor;

    operating the activating motor such that torsional excitations are generated in the rotor; and

    measuring vibrations of the rotor,wherein a transmitted torque has a first component which is constant with respect to time and a second component which is variable with respect to time,wherein the first component is achieved with an electric drive motor and the second component is achieved with the activating motor.
