Japanese Patent JP2552179
Kind Code:
B2
Abstract:
The polarized electromagnetic apparatus consists of a stationary core assembly and a movable core assembly. The movable core assembly is made up of a movable core spindle and one movable core plate attached to one end surface thereof. Since the movable core assembly has only one movable core plate as opposed to two movable core plates in the conventional apparatus, the complete movable core assembly can be installed into the electromagnetic coil, facilitating the assembly work. A pole piece is mounted to the inner surface of the stationary cores on the side of the other end surface of the movable core spindle. The second end surface of the movable core spindle is inserted into the pole piece, so that an additional attractive force can be obtained. This construction makes the overall attractive force greater than can be obtained with the conventional apparatus.
