Abstract: A linear motor is described consisting of a central pole piece disposed within a cylindrical pot magnet, the pot magnet having an end plate containing a central aperture into which the central pole piece projects to form an air gap. A magnet shield in the form of a tube is positioned coaxially with and spaced from the central pole piece and a coil is mounted for linear movement in a direction parallel to the axis of the pole piece in the air gap and in the space between the pole piece and the surrounding shield.

Abstract: A system for accelerating and decelerating a movable element of an actuator includes an inductive energy storage means, a circuit for producing a predetermined current condition in the inductor which holds the element in a balanced position and stores energy in the storage means, and switch means for discharging the storage means through the actuator to accelerate the element. The back E.M.F. developed by the motion of the element produces a current which opposes the accelerating current and thus applies to the energy store kinetic energy developed by the movement of the element.
