2-DOF Motion of an Electromagnetic Sheet Actuator Featuring Spliced Magnetic Sheets and Layered Stator Conductors

抄録

This paper presents the implementation of two-degree-of-freedom (2-DOF) motion in an electromagnetic sheet actuator. Based on the previous research on a 1-DOF linear actuator, the proposed planar actuator achieves 2-DOF motion by employing multiple spliced magnetic sheets to form a 2-DOF slider and layering driving circuits on both sides of a PCB. The actuator yields a force density of approximately 5.0 N/m² and a maximum velocity of 16.9 mm/s. Although the force density and peak velocity are reduced compared to the 1-DOF variant, the actuator successfully maintains its characteristic thin form factor.
