Abstract

A ventilator having a rotor is mounted in a rotatable manner around an axis of rotation. The rotor includes a plurality of blade-like rotor blades arranged around the axis of rotation. The ventilator includes a sensor device for detecting an object approaching one of the plurality of rotor blades, and a control device that receives signals from the sensor device. The control device extrapolates a trajectory of the object from a position x and a speed v of the object, and adjusts an angular position or rotational speed n of the rotor to allow the object to continue moving along its trajectory without colliding with one of the plurality of rotor blades.
