Claim 9:
10. The method according to claim 4, comprising:
in response to the air gap thickness decreasing, selecting or setting the control regulation to decrease the output power, decrease the generator torque and/or increase the intermediate circuit voltage,
in response to the air gap thickness decreasing, activating or setting a rotational speed avoidance control operation such that an operation of the wind power installation in a rotational speed avoidance range is avoided, and/or
setting the rotational speed avoidance control operation to increase the rotational speed avoidance range, and/or shifting the rotational speed avoidance control operation in a direction of a higher or lower rotational speed.
