Magnetic drive for electrical switching apparatuses

摘要

The invention relates to a magnetic drive (10, 20) for electrical switching apparatuses, which drive has a magnet core (14, 24) consisting of layered sheet-metal laminates (12, 22) having one or more limbs (17, 18, 27, 28) on which a moving magnet armature (15, 25) stops, which is likewise formed from sheet-metal laminates (13, 23). In the case of both the magnet core (14, 24) and the magnet armature (15, 25), the sheet-metal laminates (12, 13, 22, 23) are connected to one another by means of welding seams (16, 26), which are arranged transversely with respect to the sheet-metal layers and are produced by means of beam welding methods. <IMAGE>
