FIELD: electrical engineering. ^ SUBSTANCE: present invention relates to vibration engineering. The proposed device has an electromagnet, an armature and a stator casing, joined by a system of elastic members, consisting of extension-compression springs. Each spring has flanges on its edges, to which the armature and the stator casing are attached. The electromagnet is fixed in the stator casing. The extension-compression springs are in form of coiled spring. On each of the flanges, welded to the butt-ends of the springs, there are depressions. These depressions prevent the outermost working coils of the springs from touching the flanges during operation of the spring. The outermost coils are bent and cut such that, if the springs are compressed with maximum load, the coils do not touch. The extension-compression springs can be cylindrically shaped and profiled as well. ^ EFFECT: increased technological effectiveness of the design. ^ 1 dwg |
