摘要：The invention relates to a drive system 1 for operating an electric device. Thedrive system 1 comprises an electric motor 3 having a permanent magnet rotor 6connectable to the electric device for controlling the operation of it by a limited-anglerotation, the electric motor 3 further comprising a stator winding 8. The drive system 1

further comprises a drive circuit 2 connected to the stator winding 8. The drive system 1 ischaracterised in that the permanent magnet rotor 6 is arranged to be aligned to amagnetic field created by the stator winding 8 when supplied with current from the drivecircuit 2, so that a maximum torque is applied to the rotor 6 and thereby to the movablepart within an interval of ±25 degrees around a middle position between two endpositions of said limited-angle rotation of said rotor 6.
