Abstract
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.
Claims21
An electromagnetically actuable device having a magnetic, core proximate an armature and a coil selectively energized to draw the armature to the magnetic core, comprising:
- the armature and magnetic core being of laminated magnetic steel and having mating surfaces and at least one of the armature and magnetic core including means for integrally securing laminations together to define a conductive path proximate the mating surface to provide a shading coil.
An electromagnetically actuable device having a magnetic core proximate an armature and a coil selectively energized to draw the armature to the magnetic core, comprising:
- the armature and magnetic core including laminations of magnetic steel and having mating surfaces and at least one of the armature and magnetic core including conductive areas formed integrally with the laminations to define a conductive path proximate the mating surface to provide a shading coil.
The method of forming an electromagnet having a magnetic core and an armature comprising:
- providing an armature or magnetic core formed of laminations of magnetic steel and having a mating surface;
- and
- integrally securing the laminations together to define a conductive path proximate the mating surface to provide a shading coil.
