Abstract

PURPOSE:To prevent the generation of a beat, and to inhibit the generation of heat by mounting a permanent magnet for return adsorbing a magnetic material at the permanent magnet side of an armature to the other magnetic pole section of a yoke into a magnetic circuit between the other magnetic pole section of the yoke and a hinge section. CONSTITUTION:The yoke 22 has a pair of magnetic pole sections mutually opposed, and is arranged so as to surrounded an exciting coil 20. The armatures 24 are supported by the hinges by the yoke 22 in the hollow section of the coil 20. The armatures 24 are interrupted magnetically, and coupled mechanically, and have a pair of magnetic bars 28, 29 adsorbed to one magnetic pole section of the yoke 22 and a permanent magnet 30 mounted to one magnetic material 28. The permanent magnet 31 for return is positioned into the magnetic circuit 32 between the other magnetic pole section of the yoke 22 and the hinge section so as to be opposed at the same polarity as the permanent magnet 30 along the circuit 32.
