This paper presents a planar digital actuator based on hexagonal design. The actuator is comprised of a Mobile Permanent Magnet (MPM) surrounded by six Fixed Permanent Magnets (FPMs). The originality of the proposed actuator lies in its ability to reach six discrete positions in xy-plane with different stroke sizes (along x-axis: 0.50 mm and 1.00 mm; along y-axis: 0.86 mm). An analytical model has been developed to compute the electromagnetic and magnetic forces exerted on the MPM. Using this model, the design parameters of the actuator have been selected. A prototype has then been realized using the rapid prototyping manufacturing techniques. Through experiments, the motion behavior of the actuator has been verified. The driving current impact on the MPM displacement has been observed. For an MPM switch between two discrete positions, the obtained 10% settling time is between 10 and 20 ms.
