Abstract
A linear actuator includes an electromagnetic coil and a stator cover extending over the electromagnetic coil. A set of magnets are disposed end-to-end to form a ring. The magnets are adjacent the electromagnetic coil but offset from the center of the coil. A ferromagnetic central ring disposed within the coil at the inner diameter thereof and next to the magnets. A non-ferromagnetic ring disposed within the coil at the inner diameter thereof extending between the central ring and the other side of the stator cover. A translator is disposed between the magnets and the central axis. The translator is latchable between two positions within the linear actuator depending on the magnetic flux and the direction in which the electric current is flowing.
