FORWARD-STROKE ELECTROMAGNET Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: forward-stroke electromagnet has case 1 accommodating two coils 4,6 and armature 5. Plates 2 split into three parts along longitudinal axis are placed in flanges 3 symmetrically in respect to transverse symmetry plane of armature 5. Plates 2 are mounted so that middle strips have unidirectional sag. Ends of armature 5 are attached to centers of these strips. On side of sag of plates 2 there is adjusting nut 9 with compression spring 8 placed inside it to actuate armature. EFFECT: improved design. 4 dwg
