Stroke elongation device for an electromagnetic actuator |
摘要 |
An electromagnetic actuator is disclosed. The actuator includes a core having an inner and outer pole that defines a pole face. A coil of windings is disposed in the core and produces a magnetic field. An armature is moveable between first and second positions in response to the force produced by the magnetic field. A stroke elongation device is disposed adjacent to the outer pole piece and closely spaced from the armature. The stroke elongation device increases the pull-in force of the electromagnetic actuator.
