Abstract

PURPOSE:To enable to reduce consumption of electric power of the poralized electromagnet by a method wherein absorbing parts of armatures are arranged over and under both end absorbing parts of a nearly H type core, and the absorbing parts of the armatures are positioned as to place absorbing parts of the core between them. CONSTITUTION:A coil 2 is wound around the center part 1c of the nearly H type core 1, and the forward and the backward parts thereof consist the absorbing parts 1a, 1b. While the armatures 3-6 have the forward end absorbing parts 3a-6a, the backward end absorbing parts 3b-6b respectively, and those both end absorbing parts are connected with connecting parts 3c-6c. The armatures 3-6 are arranged over and under the core 1 as to place the absorbing part 1a between the absorbing parts 3a, 4a and 5a, 6a, and as to place the absorbing part 1b between the absorbing parts 3b, 4b and 5b, 6b. The armatures 3, 5 and 4, 6 are connected with permanent magnets 71, 72. They are held rotation-freely making the axis being at right angles to the axis of the coil 2 as the center. The armatures 3-6 are in the rotated condition when the coil 2 is not excited at first. When a current is made to flow in the coil 2, the armatures 3-6 rotate in the anticlockwise direction, and are latched in this condition.
