Abstract
PURPOSE:To facilitate miniaturization and assembling of an electromagnetic device by a method wherein a swing-free movable core, exciting coils arranged thereto, a pair of fixed cores arranged on both sides of the exciting coils, and a pair of side plates pinching permanent magnets at both sides thereof are arranged. CONSTITUTION:The movable core 2 is penetrated and is fixed at the center part with a shaft member 3 consisting of an elastic material, and the end parts of the shaft member 3 are fitted swing-freely to side plates 12, 13. The exciting coils 4, 5 are arranged as to wind around the movable core 2, and a pair of the fixed cores 6, 7 are arranged as to cover the exctiting coils 4, 5 from both the sides and form magnetic pole faces for the movable core 2 providing gaps between both the ends. The permanent magnets 8, 9, 10, 11 have the rectangular bar shape and are arranged at both the sides of the fixed cores 6, 7, and the fixed core 6 side thereof are made as S poles, the side plates 12, 13 side as N poles, the fixed core 7 side as N poles, and the side plates 12, 13 side are made as S poles. A pair of the side plates 12, 13 are consisted of a magnetic material, and are arranged at both the sides of the fixed cores 6, 7 pinching the permanent magnets 8-11. By making a current flow in the exciting coils, the movable core is made to swing in the reciprocal direction.
