| Zusammenfassung: | A fan arrangement (20) has a fan (24) driven by an electric motor (22). It further has an apparatus for continuously detecting an actual electrical value associated with the electric motor (22) during operation, an input apparatus for inputting a desired electrical value for the operation of said electric motor, a comparison apparatus (26) for comparing said electrical value with the actual electrical value, and a controller which regulates said electrical value by pulse width modulation (36). |
