A drive device comprising at least one control unit (10) for operating a first drive unit (16) with a first operating frequency (fb1) from a first operating frequency interval and a second drive unit (18) with a second operating frequency (fb2) from a second operating frequency interval, which at least partly overlaps the first operating frequency interval. The control unit (10), in at least one operating state, operates the drive units at least occasionally simultaneously with different operating frequencies (fb1, fb2) and varies the first operating frequency (fb1) and/or the second operating frequency (fb2) within the respective operating frequency interval.
