Abstract

PURPOSE:To improve the durability increasing the heat radiation together with decreasing the noise by setting a nonmagnetic body consisting of a plastically deformable metal for decreasing the vibration between gaps for linkage formed between the two iron cores. CONSTITUTION:A laminated iron core 1 consists of the first E shaped laminated iron core 1a and the second T shaped laminated iron core 1b positioned oppositely between two legs thereof. A nonmagnetic body 7 consisting of a plastically deformable metal such as lead, aluminum or the like which prevents a noise which occurs together with a vibration of the iron core 1 in use toward the upper and lower directions, is intervened between the gap 6 for linkage formed between the opposite intermediate legs 1a and 1b. Thus, the noise can be prevented and the durability can also be improved by suppressing the temperature rise due to good heat radiation.
