Abstract
A signal-processing device (34) has a desired voltage generator (VG) (40), a VG (42), a superimposing device (SD) (44), a modulator (46) and a triggering device (48). A control device (CD) (50) for a main motor connects in series to the desired VG. A CD (52) for an additional motor connects in series to the VG. Both VG outputs link to the SD inputs. The SD links to the modulator. Independent claims are also included for the following: (a) a device for controlling a static frequency changer feeding main and auxiliary motors; and (b) a drive system with main and additional motors.
