<p>PURPOSE:To make structure simple and miniature, by providing with an armature block and electromagnet block, and by uniting both the blocks so that each magnetic pole at each end of the iron core can be inserted in respective gaps defined between armature sections. CONSTITUTION:An electromagnet apparatus comprises of an armature block 1 and an electromagnet block 2. The armature block 1 comprises of two magnetic members 3, 4 between which put magnetizing sides of a permanent magnet 5. One magnetic member 3 has armature sections 3a, 3b extending vertically from the diagonal end positions respectively, while the other magnetic member 4 being in twisting relation to the one magnetic member 3 also has armature sections 4a, 4b extending vertically from the diagonal end positions. The electromagnet block 2 includes an iron core 6, around which a coil 7 is wound and which has magnetic poles 6a, 6b at both the ends. The armature block 1 and the electromagnet block 2 are united so that the magnetic poles 6a, 6b can be inserted in gaps defined between the armature sections 3a and 4b and between the armature sections 3b and 4a respectively.</p> |
