<p>PURPOSE:To hardly leak magnetic fluxes, which are generated from coils and a permanent magnet, in the middles of the generation. CONSTITUTION:A polarized electromagnet is formed to a constitution wherein it consists of a permanent magnet 1, both end parts of which are magnetized to the same pole and whose central part is magnetized into a pole different from the pole of both end parts, first and second cores 2 and 3, which are respectively provided with each one end 2a and 3a arranged on both sides of the central part of the magnet 1, first and second coils 4 and 5 wound respectively on the cores 2 and 3, first and second magnetic pole pieces 6 and 7 provided at the respective other ends of the cores 2 and 3 and moreover, first and second movable pieces 8 and 9, which are rotated by a structure wherein when the coils 4 and 5 are excited in a specified direction, roughly central parts 8a and 9a of the pieces 8 and 9 are respectively supported rotatably by both end parts of the magnet 1 and both end parts 8b and 8c and 9b and 9c are sucked by either of the pieces 6 and 7.</p> |
