摘要： Disclosed is a permanent magnetic actuator comprising: a fixed metal core having space in an inside, and having a first wall, and a second wall facing the first wall; a movable element for reciprocating sliding between the first wall and the second wall along a movable axis which connects the first wall and the second wall inside the space; a first magnetic force supply member and a second magnetic force supply member which are arranged respectively in a first wall side and in a second wall side inside the space in order to supply magnetic force for a reciprocating sliding of the movable element; more than one between the first magnetic force supply member and the second magnetic force supply member for generating a two-way magnetic force selectively; a permanent magnet for supplying coercive force for maintaining a state of the movable element by being arranged between the first magnetic force supply member and the second magnetic force supply member; and a driving circuit including a control unit for controlling a current or a voltage which is supplied to the first magnetic force supply member and the second magnetic force supply member.
