Beschreibung
Zusammenfassung:	Driving device comprising a drive shaft (5) with a drive axis (7), at least one actuator (31) exerting a drive torque on the drive shaft (5), wherein a required drive torque varies with an angular position of the drive shaft (5), and an assisting device (33) with a first magnet arrangement (35) and a second magnet arrangement (37), wherein the first magnet arrangement (35) and the second magnet arrangement (37) are displaced relative to one another with the rotation of the drive shaft (5), wherein the drive torque of the at least one actuator (31) and the assisting drive torque of the assisting device (33) provide a resulting drive torque on the drive shaft (5), wherein the assisting device (33) is a passive assisting device, and wherein the first magnet arrangement (35) comprises at least one first permanent magnet (135,136) and the second magnet arrangement (37) comprises at least one second permanent magnet (137,138). Assembly group of a weaving machine comprising such a driving device, weaving machine comprising such a driving device and method for driving a drive shaft (5) in a weaving machine comprising such a driving device.
