Abstract

PURPOSE:To improve the driving force of an armature, and to miniaturize the device while obtaining high sensitivity with small currents by winding a coil on the armature and overlapping the electromagnetic force of the coil and Lorentz force by electromagnetic force to the armature. CONSTITUTION:An upper side yoke 1 and a lower side yoke 2 are arranged oppositely, a permanent magnet 3 magnetically blocking is mounted at one end of space t between the yokes 1, 2, and the armature 4 is further put in the space t. The center of the armature 4 is pivotally supported by a shaft 5, and the coil 6 is wound on the armature 4. Currents are flowed through the coil 6 and magnetic flux is formed to the armature 4 while electromagnetic driving force (the Lorentz force) X is worked by the magnetic flux, and the driving force X is overlapped to the electromagnetic force of the armature 4. Accordingly, the driving force of the armature 4 is improved, and the electromagnet device is miniaturized while high sensitivity is obtained with small currents.
