An electromagnetic actuator device converts electrical energy to mechanical energy by the interaction of two types of closed magnetic circuits (11, 13). A first closed magnetic circuit functions to generate high magnetic intensity in a portion of a ferromagnetic core (11, 13). A second substantially-closed magnetic circuit (13) contains a movable permanent magnet (21) which injects flux into the high-end region of the first magnetic circuit (23). Interaction of these two fields, in closed magnetic circuits, results in efficient and controllable electromechanical energy conversion.
