<p>PURPOSE:To enable to miniaturize the polarized electromagnet and to enable to reduce consumption of electric power thereof by a method wherein permanent magnets are arranged at both end parts of nearly -shaped two armatures and they are connected, and an H type core being wound around with a coil is arranged inside thereof. CONSTITUTION:The coil 2 is wound around the center part of the core 1 formed in the nearly H type. The nearly -shaped armatures 31, 32 are arranged over and under the core 1 putting the core 1 between them as to be laminated. The permanent magnets 41, 42 are positioned at the outsides of absorbing parts 11, 12 of both ends of the coil 2 in the axial direction, and the armatures 31, 32 are connected by the magnets 41, 42 thereof. Before the excitation of the coil 2, the armatures 31, 32 are made to be rotated in the (a) direction. At this time, the absorbing parts, 11, 12 of the core 1 are absorbing absorbing parts 32a, 31b of the armatures 31, 32. When a current is made to flow in the coil 2, the absorbing parts 11, 31a and the absorbing parts 12, 32b are made to the absorbed condition. The armatures 31, 32 rotate in the (b) direction, and this condition is held even when the current in the coil 2 is stopped.</p> |
