ABSTRACT:
An electromagnetic actuator is disclosed. The acutator includes a core, a cylindrical shell disposed around the core which defines an annular space therebetween, and a magnetic assembly disposed about the core. The magnetic assembly including a pair of permanent magnets having opposite polarity. Also included is a coil which has first and second ends, first and second end portions, and an intermediate portion disposed between the first and second end portion. The first end is connected to the second end, and the coil is disposed in the annular space. Additionally, the coil has a plurality of windings wound in a common direction. The coil has electrically connectable leads at the end connection and the intermediate portion. An amplifier delivers an energization signal to the leads of the coil.
