• the side of the transverse yoke segments facing the wing is connected by a ferromagnetic plate with spacer strips arranged thereon.
• Within the movable wing there are permanent magnets. If the movable wing is connected to the above-described plate, the wing hangs on the stator due to the magnetic force of the permanent magnets.
