Abstract
A linear actuation assembly includes an electromagnetic coil configured to allow electric current to pass therethrough in either direction creating magnetic flux based on the electric current and its direction. The electromagnetic coil defines a center axis, an inner diameter, and first and second sides. A first set of magnets is disposed in end-to-end relation adjacent the first side of the electromagnetic coil at the inner diameter thereof. A second set of magnets is disposed in end-to-end relation adjacent the second side of the electromagnetic coil about the inner diameter thereof. The linear actuation assembly further includes at least one translator disposed adjacent the first and second sets of magnets opposite the electromagnetic coil. The at least one translator is latchable between a first position adjacent the first set of magnets and a second position adjacent the second set of magnets in response to the magnetic flux and the direction in which the electric current is flowing.
