Abstract

PURPOSE:To prevent the leak of magnetic flux and to obtain a large stroke by arranging electromagnets coaxially on the lateral side of an iron core at a prescribed interval, by connecting a rod connected with a driven body to the electromagnet positioned remotes from the iron core and by attracting the electromagnets sequentially from the remotest one. CONSTITUTION:When voltage is applied to a solenoid 24, an attracting force is generated between the electromagnets 16 and 15. However, since the electormagnet 15 is incapable of moving to the right because of the presence of a connecting wire 27, the magnet 16 moves to the left against a spring 32 and is attracted to the magnet 15. When the magnet 15 is excited while the magnet 16 is being excited, the attracting force is generated between the magnet 15 and the magnet 10, but since the magnet 10 is incapable of moving to the right by the presence of a connecting wire 26, the magnet 16 moves to the left and is attracted to the magnet 10, and finally the magnets 16, 15 and 10 are attracted integrally to the iron core 25 in the same way. Although the stroke of each magnet is small in this constitution, the leak of magnetic flux is prevented and the rod 29 fitted to the magnet 16 operates the driven body at a large stroke and by a large force as a whole.
