摘要：A drive system is disclosed for operating an electric device. The drive systemincludes an electric motor having a permanent magnet rotor connectable to the electricdevice for controlling the operation of it by a limited-angle rotation, the electric motorfurther including a stator winding. The drive system includes a drive circuit connected to
the stator winding. The permanent magnet rotor can be arranged to be aligned to amagnetic field created by the stator winding when supplied with current from the drivecircuit, so that a maximum torque can be applied to the rotor and thereby to themovable part within an interval of ±25 degrees around a middle position between twoend positions of the limited-angle rotation of the rotor.
