Welded AC electromagnet lamination assembly incorporating shading coil

摘要

An electromagnetically actuable device has a magnetic core proximate an armature and a coil selectively energized to draw the armature to the magnetic core. The armature and magnetic core are of laminated magnetic steel and have mating surfaces. At least one of the armature and magnetic core includes conductive weld or braze lines for integrally securing laminations together to define a conductive path proximate the mating surface to provide a shading coil.
