ELEKTROMAGNETISCHE BETAETIGUNGSVORRICHTUNG FUER DEN ANTRIEB EINES EINEN MAGNETKOPF TRAGENDEN ARMES |
摘要 |
An actuator comprising a transformer having a fixed primary winding on a magnetic core and a pivotally movable coil linked with the magnetic core and forming a secondary winding of the transformer. A permanent magnet generates a static magnetic field in which the coil is disposed. A transducer arm capable of pivotal movement is attached to the coil. When a current pulse is applied to the primary winding, a current is induced in the coil which reacts with the static magnetic field to cause pivotal movement of the coil and attached arm. |
