The invention relates to an operating method for a roller shutter comprising an actuator which is used to move the shutter and which consists of: a motor, an electronic control unit for powering the motor, and a control box which is connected to the electronic unit and which is equipped with at least one control key. The inventive operating method comprises at least one configuration mode, during which values that are associated with specific positions can be recorded. The invention is designed such that a roller shutter movement command only occurs after a key has been pressed during a period of time greater than a first period tif the device is not at least partially configured, but the pressing of a control key can be immediately interpreted as a command to move the mobile element if the device is at least partially configured.

A flux-switching linear motor with at least two phases P , P , P has a moving rig, two permanent magnets and a switching mechanism. The moving rig has at least two field coils . Each field coil surrounds a magnetic armature defining moving magnetic poles. The two permanent magnets are magnetized in opposite directions, transverse to the axis of a guidance stator tube . The stator tube has magnetic poles disposed along at least one of its walls so as to be successively facing the moving magnetic poles during the travel of the moving rig. The switching mechanism switches the direction of the current in the coils. The permanent magnets are disposed outside the coils and magnetized along an axis parallel to the axis of the coil. The stator magnetic poles include pieces made of magnetic material fixed in a guidance tube made of amagnetic material. The dimension of the magnets as measured along their magnetic axis is chosen so as to create narrow gaps to allow movement of the magnets past the stator poles.
