<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic solenoid device in which power consumed at the time of the operation of the electromagnetic solenoid device is reduced. <P>SOLUTION: When an exciting current is supplied to an electromagnetic coil 3, magnetic fluxes turning a magnetic circuit B are generated by the electromagnetic coil 3. At the time, to the electromagnetic coil 3, the exciting current controlled so as to generate a large amount of the magnetic fluxes more than the number of the magnetic fluxes of a permanent magnet 4, which are the magnetic fluxes in the opposite direction of the magnetic fluxes of the permanent magnet 4 passing through an iron core 2c in the iron core 2c is supplied. Thus, the magnetic fluxes of the permanent magnet 4 turning the magnetic circuit passing through the iron core 2c are pushed back by the magnetic fluxes of the electromagnetic coil 3 turning the magnetic circuit B and round the magnetic circuit C. As a result, since the composite magnetic fluxes of the magnetic fluxes of the electromagnetic coil 3 and the magnetic fluxes of the permanent magnet 4 pass through a suction 2e from an output shaft 5 and magnetic attraction force larger than the elastic force of a coil spring 6 is generated by the composite magnetic fluxes, the output shaft 5 is moved to the side of the suction 2e against the elastic force of the coil spring 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
