摘要：The device comprises an electrical actuator (2), a current source (35), a actuatingunit (37) having a limited operating range, and a control unit (41). The actuator comprises
a first actuator body having two diametrially opposed magnetic poles, and a soft-magnetic second actuator body, which is coaxial with the first actuator body and whichpreferably comprises three circumferentially equi-spaced teeth, which each carry anenergizing coil (29, 30, 31). The first actuator body and the second actuator bodycooperate with one another via an air gap and are pivotable relative to each otherthrough a specific angle about a pivotable axis. The control unit is constructed to dividethe operating range of the actuating unit into a plurality of sub-ranges and, dependingon said sub-ranges, to controllably feed a current through one of the energizing coils,through two of the energizing coils, and through all the energizing coils, respectively.
