摘要： An electromagnetic actuator (100) comprises magnets (109, 111, 113, 115, 11), and a ferromagnetic structure (103) accommodating control conductors (118, 121, 123, 125). The magnets and the structure can move with respect to one another under control of control currents in the control conductors. The magnetic field in a gap (107) between the magnets and the ferromagnetic structure is oriented perpendicular to the direction of relative movement. The structure (103) accommodates damping conductors (127) that form closed loops of an electrically conductive material, different from the ferromagnetic material. The damping conductors (127) provide a damping force induced by the relative movement.
