Disclosed is a method for balancing a fan by means of a controllable laser which is disposed outside the fan and is configured so as to generate a laser beam (12', 12", 12'"). The fan comprises a housing and a rotor (22) which is rotatably mounted therein and is embodied at least in one subarea of the rotor from a material that can be machined by the laser beam (12', 12", 12'"). At least one subarea of the fan housing is configured so as to allow the subarea of the rotor to be machined by means of a laser beam (12', 12", 12'") which is emitted by the laser and extends through the subarea of the housing to the subarea of the rotor. The inventive method encompasses the following steps: A) the rotor of the fan is made to rotate (S750), and the unbalance created by the fan is measured in order to determine at least one machining point in the subarea of the rotor for reducing the unbalance (S760); B) the laser is triggered so as to generate a laser beam (12', 12", 12'") such that the same penetrates the subarea of the rotor approximately at the at least one machining point (92) in order to remove material there (S780). |
