A method for preserving the constant moment in dynamic closing process of an electromagnetic suction-operated device is suitable for traction electromagnets, valve electromagnets and other similar electromagnetic suction-operated devices. A moving armature with fixed closing characteristic and a force-changing lever which can change the arm in dynamic process are used. By means of this method, the device has less starting airspace an larger suction force and can preserve constant moment in closing process.Thus the device can make full use of the energy and has features of small volume, large suction force and saving energy. Its dynamic operating principle is shown in drawing. |
