  • Permanent magnet operating device
    Patent number: 9966215
    Abstract: The disclosure relates to a permanent magnet actuator comprising: a stator iron core having a space therein-side, and having a first wall and a second wall opposing the first wall; a movable element moving reciprocally between the first wall and the second wall, along a moving axis which connects the first wall and the second wall inside the space; a first magnetomotive force supplying body and a second magnetomotive force supplying body disposed respectively on the first wall and the second wall, so as to supply a magnetomotive force to the movable element for the reciprocal movement thereof, wherein, at least one of the first magnetomotive force supplying body and the second magnetomotive force supplying body selectively produces a bidirectional magnetomotive force; a permanent magnet disposed between the first magnetomotive force supplying body and the second magnetomotive force supplying body, and providing a coercive force to the movable element for maintaining the state thereof; and a driving circuit co
