PRINCIPLE AND CONSTRUCTION OF AN ELECTRICAL ACTUATOR?

         The actuator consists of a not movable part called the stator and a movable part the rotor or armature. Both parts are separated by an air gap, whose thickness can variate between about 0,1 mm to 2 mm. Magnetic an air gap is a disadvantageously property and should be as small as possible. Both the stator and rotor can contain windings or permanent magnets. As described above the important parts are:
The stator
The rotor
The windings
