Several constructions of electromagnetic actuators with moving permanent magnet for Braille screen are studied. All they are formed from a basic one that con- sists of two coils, core and moving permanent magnet. The fini te element method is used for modelling of the magnetic field and for obtaining the electromagnetic force acting on the mover. The static force-stroke characteristi cs are obtained for four differ- ent constructions of the actuator. The constructions with f erromagnetic disc between the coils ensure greater force than the ones without disc and can reach the required minimum force.
