Design of a High Power Density Electromagnetic Actuator for a Portable Braille Display
Tiene Nobels, Frank Allemeersch, Kay Hameyer · 2002
Refreshable Braille displays are generally large and expensive. This paper presents the design of a small and inexpensive linear electromagnetic actuator, which allows a considerable reduction in size and cost of refreshable Braille displays. The actuator concept is optimised with electromagnetic finite element simulations, which are verified with measurements on a prototype.
