Abstract

PURPOSE:To achieve a less-acoustic noises, less-heat generation AC electromagnet by a method wherein a pair of ?-shaped iron cores are made embracing each other via a magnetic shielder made of synthetic resin or the like and a gap is built in each iron core, in which permanent magnets with an inverse polarity for each other are fitted, and an excitation coil is wound on each iron core including one of these permanent magnets. CONSTITUTION:A magnetic shielder 21 made of synthetic resin or the like is embraced between a pair of ?-shaped iron cores 20a and 20b which are insulated magnetically. Next, an armature 22a is bridged between both magnetic poles 23a and 23b of the iron core 20a, and likewise an armature 22b is bridged between both magnetic poles 24a and 24b of iron core 20b, and armature 22a is isolated from armature 22b with a magnetic shielder 28. In this construction, a gap 27 is built in each of iron cores 20a and 20b, and permanent core 26a and permanent core 26b having an opposite polarity to 26b are mounted on this gap to increase magnetic resistance of the magnetic circuit. Then, an excitation coil 29 is wound via a spool astride on both the iron cores including these permanent cores.
